Entropion is a condition where the eyelid turns inward and the lashes rub against the eye. It most often affects older adults, and the early symptoms of entropion can include irritation, tearing, redness, and a feeling that something is in the eye. Entropion may be constant or come and go at first, but it often lasts until it is treated. Not everyone will have the same experience. Entropion is usually not life-threatening, and treatment often includes lubricating drops or ointment, tape or stitches in some cases, and minor surgery to correct the eyelid position.
How many people live with Entropion?
Worldwide and U.S. prevalence estimates for entropion, where the eyelid turns inward, are not consistently reported by a single authoritative source, so there is no widely accepted headcount for how many people live with it. Most published information describes it as uncommon overall and more common in older adults, but the exact number worldwide and in the United States remains unclear.
Overview
EntropionSymptoms
Entropion makes the eyelid turn inward, so lashes rub against the eye. People with entropion often notice irritation, tearing, redness, light sensitivity, and a gritty feeling, as if something is in the eye.
Outlook and prognosis
With entropion, the outlook is usually very good once the eyelid is treated, often with a small procedure. Until then, inward-turning lashes can keep irritating the eye and, if ignored, may scratch the cornea and affect vision.
Causes and risk factors
Entropion usually results from age-related eyelid laxity, scarring after injury, infection, or surgery, or muscle spasm. Risk rises with older age, prior eye inflammation, trauma, burns, and rarely, being born with it.
Genetic influences
Genetics usually play only a small role in entropion. Most cases happen later in life from age-related tissue changes, scarring, or muscle imbalance rather than inherited gene changes. Rarely, entropion can run in families or appear with certain genetic conditions.
Diagnosis
Entropion is usually diagnosed during an eye exam, based on the eyelid turning inward and related eye irritation. Your clinician may check the eyelid position, blinking, and tear film. Imaging or genetic tests are not usually needed.
Treatment and drugs
Entropion treatment focuses on protecting the eye and turning the eyelid back out. Lubricating drops or ointment can ease rubbing. Lasting relief usually comes from a small eyelid-tightening procedure.
Symptoms
An eyelid that turns inward can make each blink feel scratchy, watery, and hard to ignore. In entropion, the lashes or skin rub against the front of the eye, and the early symptoms of entropion often start with irritation that comes and goes. Symptoms vary from person to person and can change over time.
It may feel like sand, dust, or an eyelash is stuck in the eye, especially when you blink. For many people with entropion, this rubbing is the first symptom they notice.
Constant rubbing can leave the white of the eye looking pink or red. The eyelid may also feel sore, tender, or generally irritated.
The eye often makes extra tears in response to irritation, so it may water even when you are not crying or out in the wind. In entropion, this can come and go through the day and may briefly blur your vision.
Bright light, wind, or dry air can make the eye feel much more uncomfortable. Some people find themselves squinting, blinking more, or keeping the eye partly closed.
How people usually first notice Entropion?
People usually first notice entropion when the edge of the lower eyelid starts turning inward, so the lashes rub against the eye and make it feel gritty, irritated, or unusually watery. For many people, the first signs of entropion are redness, sensitivity to light, a feeling that something is stuck in the eye, or blurred vision from constant tearing. Because these symptoms can seem minor at first, many living with entropion only realize something is wrong when the discomfort keeps coming back or the eye looks persistently sore.
Types of Entropion
Entropion can affect day-to-day comfort in different ways depending on why the eyelid turns inward. Symptoms don’t always look the same for everyone. Doctors usually describe several types of entropion, based on what is causing the lid to roll in, and the different types of entropion can vary in who gets them and how suddenly symptoms appear.
Involutional
This is the most common type and usually happens with aging, when the lower eyelid tissues become looser over time. Many people notice ongoing irritation, watering, redness, and a scratchy feeling as the lashes rub against the eye.
Cicatricial
This type happens when scarring on the inner eyelid pulls the lid inward. It can develop after infections, injury, inflammation, or prior surgery, and symptoms may feel more persistent or severe because the lid is being mechanically tugged out of position.
Spastic
This type is caused by forceful squeezing of the eyelid muscles, often triggered by pain, dryness, inflammation, or irritation in the eye. It may come on suddenly or off and on, so one day the eye may feel only mildly irritated and the next it may water a lot and feel very sore.
Congenital
This rare type is present at birth and happens when the eyelid develops in a way that turns it inward. Babies may have eye irritation, tearing, or sensitivity to light, though severity can vary depending on how much the lashes touch the eye.
Can I slow down the onset of symptoms?
Usually no—there is no strong evidence that lifestyle changes can meaningfully delay the start of entropion, where the eyelid turns inward, especially when it is caused by aging changes in the lid. Getting eye infections, ongoing irritation, and eyelid scarring treated early may help lower the chance of some cases, but research is limited, and lowering risk is not the same as preventing entropion. If symptoms begin, an eye doctor can offer well-established treatments to protect the eye and, when needed, surgery to fix the lid, so early care can still make a real difference in comfort and eye safety.
What genetics can tell you about symptoms
For most people with entropion, genetics does not tell us much about which symptoms will happen, how severe they will be, or when they will start, because this condition is usually linked to aging changes, scarring, irritation, or muscle imbalance in the eyelid rather than an inherited gene change. In day-to-day life, that means symptoms such as eye redness, watering, a scratchy feeling, light sensitivity, or blurry vision are usually better explained by how much the lashes and eyelid are rubbing on the eye than by family history. Rarely, entropion can be present from birth or occur as part of an inherited condition, and in those cases genetics may help explain earlier onset or related eye and skin features.
Causes and risk factors
For many, entropion starts when the lower eyelid becomes lax with age, so the lid rolls inward and the lashes rub the eye. Scarring after an injury, burn, infection, or past surgery can also pull the eyelid inward. Doctors distinguish between risk factors you can change and those you can’t. Rarely, entropion is present from birth because the eyelid formed differently, and this can be linked to certain inherited conditions. Common causes and risk factors for entropion include older age, facial nerve weakness, long-term eye irritation, frequent eye rubbing, and a history of trauma or surgery around the eye.
What are the most common causes or risk factors?
The most common cause of entropion, where the eyelid turns inward, is aging because the tissues and muscles that hold the lower lid in place can loosen over time. Other major risk factors include scarring from past eye infections, burns, injury, or surgery, as well as ongoing eye irritation or swelling that makes the lid pull inward; less often, it can happen from muscle spasms or other problems that affect how the eyelid moves. Entropion is usually not inherited, but a small number of people are born with it because the eyelid did not form in the usual way.
Environmental and biological risk factors
Entropion is more likely when the eyelid loses support or gets pulled inward, so blinking can start to feel scratchy and the eye may water or sting. The most common risk factors for entropion are older age, scarring, and prior surgery or injury around the eye. Doctors often group risks into internal (biological) and external (environmental).
Entropion is most common in older adults because the muscles and tendons that support the eyelid can loosen over time. As that support weakens, the lid is more likely to roll inward.
Scarring on the inner eyelid or nearby tissues can pull the lid inward. This may happen after long-term inflammation or certain infections that heal with scar tissue.
Previous surgery on the eyelid, eye, or nearby face can change how the lid sits against the eye. Scar tissue or altered support can raise the chance of entropion later on.
A cut, burn, or chemical injury around the eye can distort the normal shape of the eyelid. Even after the area heals, tightening scar tissue may keep pulling the lid inward.
Genetic risk factors
If entropion shows up early in life or seems to run in a family, genes may be part of the reason. The genetic risk factors for entropion mostly involve how the eyelid and nearby facial structures develop before birth. Some risk factors are inherited through our genes. Inherited causes are uncommon overall, but they matter most in rare forms present from birth and in certain genetic syndromes.
Family history: Entropion can sometimes run in families, especially when relatives share similar eyelid shape or support. This does not mean it will definitely happen, but it can raise the chance.
Congenital form: Some babies are born with entropion because the eyelid formed differently before birth. This rare form may happen on its own or as part of an inherited pattern.
Rare syndromes: A small number of inherited conditions that affect eyelid or facial development can include entropion as one feature. In these situations, the inward-turning lid is often not the only finding.
Inherited anatomy: The shape of the eyelids and surrounding tissues can be passed down in families. In some people, these inherited features make entropion more likely, especially early in life.
Lifestyle risk factors
Lifestyle habits are usually not the main cause of entropion, but some behaviors can worsen eyelid irritation, speed tissue damage, or make symptoms harder to control. When people ask about lifestyle risk factors for entropion, the clearest links are habits that increase chronic eye inflammation, rubbing, or delayed healing. Reducing these factors may help limit discomfort and lower the chance of worsening in people already prone to the condition.
Frequent or forceful eye rubbing can irritate the eyelid margin and worsen laxity or inward turning over time. It can also scratch the cornea and make pain, tearing, and light sensitivity more severe.
Smoking can promote tissue aging, poor circulation, and delayed healing in the eyelids and ocular surface. It may also worsen dry eye and irritation, which can aggravate symptoms when entropion is present.
Neglected eyelid hygiene can allow blepharitis and chronic inflammation to persist. Ongoing inflammation can increase swelling, discomfort, and eyelid changes that make entropion harder to manage.
Overwearing contact lenses or using them despite irritation can increase ocular surface stress and inflammation. In someone with entropion, this may worsen redness, pain, and corneal injury.
Risk prevention
Entropion can make everyday things like reading, driving, or walking outside feel irritating because the eyelid turns inward and the lashes rub against the eye. Many cases happen with aging or after scarring, so entropion cannot always be fully prevented, but some risks can be lowered and complications can often be avoided. Prevention is about lowering risk, not eliminating it completely. Paying attention to eye irritation, redness, watering, or the early symptoms of entropion can also help people get treatment before the cornea is damaged.
Prompt treatment of eye infections, eyelid inflammation, and long-term irritation may help lower the chance of scarring that can lead to entropion. If your eyes often feel gritty or sore, getting them checked early can help protect the eyelid and the eye surface.
Avoiding eye injuries can reduce a preventable cause of entropion. Protective eyewear during sports, yard work, construction, or chemical exposure helps lower the risk of burns, cuts, and later scarring.
Skin and eyelid scarring after burns, trauma, or surgery can pull the lid inward over time. Good wound care and follow-up with a doctor or eye specialist may help limit changes that raise the risk of entropion.
Routine eye exams are especially helpful for older adults and for people who have had eyelid surgery, facial weakness, or eye scarring. Prevention works best when combined with regular check-ups.
Can you prevent Entropion?
Entropion, where the eyelid turns inward, usually cannot be fully prevented, especially when it happens with aging. Some cases may be less likely if eye infections, ongoing eye irritation, and eye injuries or burns are treated quickly, because scarring can pull the lid inward. Even with good eye care, many people living with entropion could not have prevented it.
Transmission
Entropion is not infectious, so it cannot be passed from one person to another through touch, coughing, kissing, shared towels, or close contact. If you are wondering whether entropion is contagious, the answer is no.
In most people, entropion happens because the eyelid tissues loosen with age, or because of scarring, irritation, muscle spasm, or an injury; a small number of babies are born with it. That means people with entropion do not need to worry about giving it to family members, although the eye irritation and rubbing on the eye should still be checked and treated.
When to test your genes
For entropion, genetic testing is not part of early detection or routine care. This condition is usually caused by aging, scarring, muscle weakness, or irritation rather than inherited DNA changes. If eyelid turning runs strongly in your family or starts unusually early, an eye specialist can decide whether any broader evaluation is worth considering.
Diagnosis
Entropion is usually diagnosed during an eye exam after symptoms such as eye irritation, tearing, or the feeling that something is rubbing on the eye start to interfere with daily life. Many living with entropion notice discomfort when reading, walking outside in wind, or waking with a red, watery eye. Doctors usually begin by looking closely at the eyelid position, the surface of the eye, and how the lid moves when you blink.
The doctor asks about eye watering, redness, light sensitivity, blurred vision, and the feeling of lashes scraping the eye. This helps connect day-to-day symptoms with the diagnosis of entropion and shows how urgent treatment may be.
A close look at the eyelid often shows that the lid margin has turned inward and the eyelashes are touching the eye. The doctor may check whether this happens all the time or only when you squeeze your eyes shut or blink.
The front of the eye is examined for irritation, scratches, or damage caused by rubbing lashes. Special dye drops may be used to highlight small areas of injury that are otherwise hard to see.
Gentle pulling and releasing of the eyelid can show whether the tissues are too loose, which is a common cause in older adults. The doctor may also ask you to close your eyes tightly to see if muscle spasm worsens the inward turning.
How is Entropion diagnosed?
Entropion is usually diagnosed during a simple eye exam, when a doctor or eye doctor looks closely at the eyelid and can see that it is turning inward and the lashes are rubbing against the clear front surface of the eye. They will also ask about symptoms such as watering, irritation, blurred vision, or the feeling that something is in the eye, and may check how the eyelid moves when you blink or squeeze your eyes shut. Scans or genetic tests are not usually needed.
Stages of Entropion
Entropion does not have defined progression stages. That is because it is usually described by how much the eyelid turns inward and how much it irritates the eye, rather than by a set step-by-step course over time. Doctors usually start with a conversation about symptoms such as eye redness, watering, a gritty feeling, light sensitivity, and the early symptoms of entropion, then examine the eyelid and the surface of the eye. Follow-up is based on whether the eyelid is causing ongoing rubbing against the cornea, which can raise the risk of scratches, infection, or vision problems.
Outlook and prognosis
With timely treatment, the outlook for entropion is generally excellent, and most people have good relief of irritation, tearing, light sensitivity, and the sensation of something rubbing on the eye. Temporary measures such as lubricating drops, ointments, tape, or botulinum toxin can ease symptoms, but recurrence is more likely unless the underlying eyelid position is corrected. When surgery is needed, success rates are high, although some people may need repeat treatment if the eyelid turns inward again. The main risk to prognosis comes from delayed care, because ongoing friction from the lashes can injure the cornea and lead to infection, scarring, or vision loss. Entropion itself is not usually life-threatening and does not typically affect overall life expectancy, so mortality is not expected to be increased directly by the condition.
Long-term effects
With entropion, the eyelid turns inward, so the lashes and skin keep rubbing against the eye. Over time, this can be more than just irritating: it may affect comfort, vision, and the health of the clear front surface of the eye. Thinking about the long-term effects helps explain why ongoing irritation from entropion should not be ignored, especially if the early symptoms of entropion keep coming back.
Constant rubbing can cause burning, redness, watering, and the feeling that something is stuck in the eye. For many people with entropion, these symptoms can flare throughout the day, especially in wind, bright light, or while reading.
Repeated friction can scratch the cornea, the clear front layer of the eye. If this keeps happening, it may lead to sores, scarring, or clouding that can affect sight.
Blurred vision may develop when the eye surface becomes irritated or damaged. Some people with entropion find that vision comes and goes at first, then becomes more persistently affected if corneal injury develops.
A sore, inflamed eye often becomes unusually sensitive to light. This can make outdoor time, screen use, or driving feel harder than usual.
How is it to live with Entropion?
Living with entropion can feel like having an eyelash or grain of sand trapped in your eye all day, because the eyelid turns inward and the lashes rub against the eye’s surface. Many people with entropion deal with tearing, redness, irritation, light sensitivity, and blurred vision, which can make reading, driving, screen use, and being outdoors more difficult. If it is not treated, the constant rubbing can injure the clear front of the eye and affect vision, but treatment is often very effective. For people around you, it may mean noticing that your eye looks watery or sore and that you may need help with tasks like transportation or errands when symptoms flare.
Treatment and drugs
Entropion is treated by protecting the eye, easing irritation, and correcting the eyelid so it no longer turns inward and rubs against the surface of the eye. Temporary care may include lubricating eye drops or ointment, soft contact lenses used as a protective bandage, or small tape strips placed on the eyelid to pull it into a safer position. If inflammation or infection is present from constant rubbing, doctors may also use antibiotic drops or ointment, but medicines alone usually do not fix entropion itself. The main long-term treatment for entropion is a small procedure or surgery to tighten and reposition the eyelid, especially when age-related tissue changes are the cause. Finding the right therapy can take some time, but prompt treatment helps prevent corneal scratches, pain, and vision problems.
Can you cure Entropion?
Entropion usually can be corrected, and surgery is the main treatment because it puts the eyelid back in the right position. Eye drops, ointment, or special tape can help protect the eye and ease irritation for a while, but they do not fix the underlying problem. Once treated, many people do well, although the eyelid can sometimes turn inward again later.
Non-drug treatment
Entropion can make everyday things like reading, walking outside, or blinking feel irritating because the eyelid turns inward and the lashes rub on the eye. Treatment usually focuses on protecting the surface of the eye, easing discomfort, and correcting the lid position when needed. Managing this condition often means using simple temporary measures first, while planning a more lasting fix if the problem keeps coming back.
Special skin tape can gently pull the eyelid outward so the lashes stop scraping the eye. This can give short-term relief during the day or while waiting for a procedure.
A soft bandage contact lens can act like a shield between the eyelashes and the clear front surface of the eye. Some people with entropion find this especially helpful when blinking feels painful or the eye is tearing constantly.
Artificial tears and lubricating ointment can reduce friction and help protect the eye from dryness and scratching. When people ask about non-surgical treatment for entropion, these are often part of the first steps, but they do not correct the eyelid itself.
A doctor can place small stitches to turn the eyelid outward for a period of time. This is usually a temporary option, but it can help if surgery needs to be delayed or if a quick office-based treatment is needed.
Your genes may have an impact on how drugs work for you
For people with entropion, genes usually do not play a big role in how treatment works, because the main problem is the eyelid turning inward and rubbing the eye, and that is often helped with eye drops, ointment, tape, or a procedure to put the lid back in the right position. The medicines used here mostly protect the eye and ease irritation, like when the eye feels scratchy or watery all day, rather than changing the underlying cause. If medicine is needed around surgery, doctors usually choose and adjust it based on your symptoms, age, and overall health, not on genetic testing.
Pharmacological treatments
Treatment for entropion mainly aims to protect the eye and ease irritation until the eyelid can be corrected, often with a procedure. Medicines do not usually fix entropion itself, but they can help with pain, dryness, and damage to the cornea. Some medicines are used for short-term relief, while others are used if entropion has caused a scratch or infection on the eye surface.
Lubricating eye drops such as carboxymethylcellulose or hypromellose can help reduce dryness, grittiness, and rubbing from the inward-turned lid. For many living with entropion, these are often used during the day to protect the front of the eye.
Thicker eye ointments such as petrolatum-mineral oil or lanolin-based products can coat the eye longer, especially at night. They are often helpful when early symptoms of entropion are worse on waking or when the eye does not fully close during sleep.
If entropion leads to a corneal scratch or eye infection, doctors may prescribe antibiotic drops or ointment such as erythromycin or bacitracin-polymyxin B. These medicines treat infection risk, but they do not correct the eyelid position.
Botulinum toxin injections, often called Botox, can sometimes be used in certain types of entropion to relax the muscles pulling the lid inward. The effect is temporary, so this is usually a short-term option or a bridge while waiting for surgery.
Genetic influences
Most entropion is not caused by a single inherited gene and, in adults, it usually happens because the eyelid tissues loosen with age or after scarring. It’s natural to ask whether family history plays a role. Genetics may matter more when entropion starts at birth or in childhood, or when several relatives have similar eyelid problems, because inherited differences in eyelid shape, skin, or the tissues that support the lid can make the eyelid turn inward more easily. Rare genetic conditions that affect the skin, muscles, or facial development can also include entropion as one feature. So if you are wondering whether entropion can run in families, the answer is sometimes, but most cases are not strongly inherited. When entropion appears early, affects both eyes, or shows up in several family members, talking with an eye specialist and, in some cases, a genetics professional can help clarify whether there is an inherited factor.
Is Entropion genetic?
Genetics usually play only a small role in entropion. Most cases happen later in life from age-related tissue changes, scarring, or muscle imbalance rather than inherited gene changes. Rarely, entropion can run in families or appear with certain genetic conditions.
Having a genetic risk is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely found in the general population. Most do not directly affect health and simply reflect natural human diversity. In many genes, carrying a variant associated with a condition points to a possible link rather than a certain diagnosis, especially when several genes and environmental factors also play a part. In some situations, though, a single well-understood variant in a particular gene is enough to confirm the diagnosis.
Pharmacogenetics—how genetics influence drug effects
For many living with entropion, treatment is usually chosen by the cause of the eyelid turning inward and by how much the eye is being irritated, not by genetic testing. Lubricating drops or ointments, skin tape, or a small muscle-relaxing injection may help for a time, while surgery is often the longer-term fix. Not every difference in response is genetic, but if entropion appears as part of a rare inherited condition that affects the skin, muscles, or eyelids, genetic information can help doctors look for related health issues and plan care more broadly. In most cases, though, the medicines used to protect the eye and ease symptoms in entropion are not selected based on your genes. If you are wondering about genetic causes of entropion, that question matters most when the problem starts early in life, runs in families, or happens along with other unusual eye or facial features.
Interactions with other conditions
For many people, entropion does not happen on its own, and it can be more common alongside conditions that weaken or scar the eyelid. Problems such as long-term eyelid inflammation, eye infections that leave scarring, dry eye disease, or disorders that tighten the skin and lining of the eyelid can all make entropion worse or harder to manage. Someone might notice their symptoms flare when another condition is active, such as during a bad bout of blepharitis or when dry eyes become more irritating, leading to more rubbing, tearing, and a scratchy feeling. Entropion can also matter more in people living with corneal disease, because the turned-in lashes may keep rubbing the clear front surface of the eye and raise the risk of scratches, infection, or worsening vision. In older adults, age-related loosening of the eyelid often overlaps with other eye problems like cataracts or glaucoma, which may not cause entropion but can make eye discomfort and treatment planning more complicated. If you are dealing with repeated eye irritation or the early symptoms of entropion along with another eye condition, it is worth having both checked so the main cause is treated and the eye is protected.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Entropion?
Symptoms like eye watering, redness, irritation, and the feeling that something is scratching the eye can also happen with eyelashes that grow in the wrong direction, dry eye, eyelid inflammation, pink eye, or a scratch on the clear front part of the eye. Sometimes an outward-turning eyelid can also cause similar discomfort, so an eye doctor may need to look closely to tell these problems apart.
History
People have likely lived with inward-turning eyelids for as long as humans have recorded eye problems. Long before modern eye clinics, doctors noticed that when the eyelid rolls inward, the lashes can rub against the surface of the eye, causing pain, watering, redness, and trouble keeping the eye open in bright light. For many, this would have shown up in very ordinary moments, like blinking while reading or stepping outside on a windy day and feeling a constant scratchy irritation.
Ancient and medieval medical texts described eyelid problems that match what we now call entropion, even if the names and explanations were different. Early doctors worked from what they could see: the lid turning in, the lashes touching the eye, and the damage that could follow if this went on for too long. They understood the day-to-day impact well, even without the tools we have now to examine the eye in detail.
Over time, the way the condition has been understood has changed, but the main concern has stayed the same: protecting the eye from ongoing friction and injury. As eye medicine developed in the 1800s and 1900s, doctors became better at separating entropion from other eyelid conditions that can also make the eye sore or watery. This helped make treatment more precise, especially for older adults, who are more likely to develop the most common form as the tissues around the eyelid loosen with age.
Surgery for entropion also evolved. Earlier procedures were often based on visible anatomy and practical experience, while modern treatments are planned with a clearer understanding of which part of the eyelid has become too loose or is pulling in the wrong direction. That matters because the best approach can differ depending on whether the eyelid problem is linked to aging, scarring, muscle spasm, or a less common cause present from birth.
In recent decades, awareness has grown that early symptoms of entropion should not be brushed off as simple dry eye or irritation. Today, doctors know that repeated rubbing from the lashes can injure the clear front surface of the eye and, in some cases, threaten vision if not treated. Knowing this history helps explain why prompt diagnosis and treatment are now such an important part of care for people with entropion.
