Congenital alacrima is a rare genetic condition in which the tear glands do not make enough tears. People with congenital alacrima often have eye dryness, irritation, burning, or a feeling of grit, and doctors may see a dry, red surface of the eye. It usually starts in infancy or early childhood and is lifelong, though severity can vary. Treatment focuses on eye lubrication with artificial tears, gels, or ointments, and sometimes punctal plugs or special goggles. Most people with congenital alacrima have a normal lifespan, but regular eye care helps prevent damage from long‑term dryness.
Overview
Congenital alacrimaSymptoms
Congenital alacrima causes little or no tears from birth. Common signs include dry, irritated, or red eyes, no tears when crying, frequent eye infections, light sensitivity, and, over time, potential corneal damage or blurry vision if dryness isn’t treated.
Outlook and prognosis
Most people with congenital alacrima can protect their eyes well with regular tear replacement and careful eyelid care, though dryness tends to be lifelong. Eye checkups help prevent scratches, infections, and vision changes. Outlook varies if adrenal or nerve issues are also present.
Causes and risk factors
Usually due to underdeveloped tear glands or genetic syndromes (e.g., Triple A/Allgrove, LADD), most often inherited from both parents (autosomal recessive). Risk rises with family history or parental relatedness. Environmental or lifestyle factors are not known primary drivers.
Genetic influences
Genetics plays a central role in congenital alacrima. Many cases result from inherited variants—often autosomal recessive—in genes affecting tear gland development or function, such as ALDH1A3 or those linked to triple-A (Allgrove) syndrome. Family history can guide testing and counseling.
Diagnosis
Diagnosis of congenital alacrima relies on absent tearing from birth, confirmed by tear production tests and eye-surface staining. Clinicians may image lacrimal glands and use genetic tests. These findings support the genetic diagnosis of congenital alacrima.
Treatment and drugs
Treatment focuses on easing dry eyes and protecting the surface. People with congenital alacrima often use frequent preservative‑free artificial tears, thicker gels or ointments at night, and moisture goggles; plugs or cautery may help keep tears longer. Regular eye checks monitor cornea health.
Symptoms
Congenital alacrima can show up early as dry, easily irritated eyes that don’t stay comfortable without drops. Parents sometimes notice early features of Congenital alacrima, such as a baby who cries without tears. Loved ones often notice the changes first. As kids grow, dryness can affect reading, screens, and outdoor time, and in adults it may cause fluctuating vision or light sensitivity.
Eyes may feel sandy or scratchy, especially in wind, air conditioning, or during screen time. Frequent blinking or needing lubricating drops is common.
Babies and children may cry without visible tears, even with strong emotions or minor injuries. In congenital alacrima, the tear reflex with cutting onions or eye irritation may also be weak or absent.
Bright light can feel harsh and uncomfortable. Sunglasses or hats may help reduce discomfort outdoors.
Vision may blur at times, then clear after blinking or using drops. With congenital alacrima, this often reflects an unstable tear film over the eye.
How people usually first notice Congenital alacrima?
Many families first notice something is different when a newborn doesn’t produce tears while crying, so the eyes look dry even during a full cry. In the first months, doctors or caregivers may spot persistent dry, irritated eyes, frequent blinking, light sensitivity, or recurrent eye redness and infections, prompting an eye exam that confirms absent or greatly reduced tear production. Because congenital alacrima can occur on its own or as part of a broader syndrome, some children are first recognized during routine check-ups for dry eyes alongside other early clues like feeding difficulties, poor weight gain, or autonomic symptoms, which helps clinicians identify the first signs of congenital alacrima and how congenital alacrima is first noticed.
Types of Congenital alacrima
Congenital alacrima is present from birth and means the tear glands don’t make enough tears. Variants and related syndromes can look different in how early dry eye shows up and which body systems are involved. Clinicians often describe them in these categories: stand‑alone congenital alacrima, syndromic forms where tear problems appear alongside other features, and rare structural gland issues. Knowing the types of congenital alacrima can help explain why symptoms vary from mild gritty eyes to severe dryness with eye surface damage.
Isolated alacrima
Dry eye symptoms start early in life without other medical problems. People may have burning, frequent blinking, or trouble keeping contact lenses comfortable. Eye exams often show a reduced tear film.
Triple A syndrome
Alacrima occurs with swallowing problems from a tight esophagus and adrenal hormone deficiency. Some may also have growth, blood pressure, or nerve issues over time. Early symptoms of congenital alacrima can be the first clue.
Lacrimal gland aplasia
The tear glands are underdeveloped or absent from birth. Dryness tends to be more severe and noticed in infancy or early childhood. Doctors see very low or no tear production on testing.
Other syndromic forms
Alacrima appears as part of certain rare genetic syndromes affecting development. People may notice eye dryness along with features such as facial or limb differences, or nerve involvement. Not everyone will experience every type.
What genetics can tell you about symptoms
Variants in the AAAS gene can disrupt tear gland development or nerve signaling, leading to very dry eyes from infancy, eye irritation, and recurrent infections. In triple A (Allgrove) syndrome, the same gene changes can add swallowing trouble, adrenal crises, and nerve problems.
Causes and risk factors
Congenital alacrima usually happens because the tear glands did not form or do not work from birth.
This often traces to genetic changes, including those inherited from both parents in Triple A (Allgrove) syndrome, or to syndromes that affect gland development like LADD.
Risk is higher when there is a family history of these conditions, or when parents are closely related by blood.
Some risks are modifiable (things you can change), others are non-modifiable (things you can’t).
Dry climates, long screen time, contact lenses, and medicines that reduce tears can make early symptoms of congenital alacrima feel worse, but they do not cause it.
Environmental and biological risk factors
Congenital alacrima begins before birth when the structures that make tears do not form or connect as expected. Doctors often group risks into internal (biological) and external (environmental). Here are environmental and biological influences that may increase the chance of congenital alacrima, especially when they occur early in pregnancy.
In the first trimester, the tiny buds that become tear glands start to grow and branch. Disruptions in this early facial development can lead to absent or underdeveloped glands. This raises the chance of congenital alacrima.
The signal pathways that tell the tear glands to make tears form early in fetal life. If these nerves don’t connect properly, the glands may not produce tears even if present. This biological difference can contribute to alacrima.
Diabetes present before or early in pregnancy has been linked to differences in craniofacial development. These changes can involve the eyes and nearby glands that make tears.
Some broader birth conditions affect several organs and include underdeveloped or missing tear glands. When these syndromes are present, the likelihood of congenital alacrima is higher.
Genetic risk factors
Congenital alacrima can run in families when gene changes affect how the tear glands form or work. The best-understood genetic causes of congenital alacrima include certain single-gene conditions that are present from birth. Carrying a genetic change doesn’t guarantee the condition will appear, and severity can vary even within the same family. Knowing the specific cause can guide family planning and testing of relatives.
AAAS gene: Changes in the AAAS gene cause Triple A (Allgrove) syndrome, an autosomal recessive condition where congenital alacrima is often the earliest sign. When both parents are carriers, each child has a 25% chance to be affected.
LADD genes: Variants in FGF10, FGFR2, or FGFR3 can cause LADD syndrome, which affects development of the lacrimal and salivary glands. This autosomal dominant pattern can lead to congenital alacrima with variable severity in the same family.
NGLY1 deficiency: Pathogenic changes in NGLY1 commonly lead to alacrima along with developmental and neurologic features. This is an autosomal recessive disorder, and many affected children show very low or absent tear production from infancy.
Familial dysautonomia: ELP1 gene variants cause this autosomal recessive neurologic condition that reduces or abolishes tear production. It is much more common in people with Ashkenazi Jewish ancestry and can present with congenital alacrima.
Family history: Having a close relative with a known genetic diagnosis linked to alacrima increases the chance of the same condition in the family. Targeted genetic testing can clarify whether you carry the same variant.
Consanguinity: Parents who are related by blood have a higher chance of sharing the same rare recessive variant. This increases the likelihood of autosomal recessive causes of congenital alacrima in their children.
Unknown genetic cause: Some people have congenital alacrima without an identified gene change on standard panels. Broader testing, such as exome or genome sequencing, may be discussed with a genetics team.
Lifestyle risk factors
Congenital alacrima is not caused by lifestyle habits, but daily choices can strongly influence eye comfort and the risk of complications like corneal injury. Managing routines that affect blinking, surface lubrication, and hydration can make symptoms more or less severe. Below are practical lifestyle risk factors for congenital alacrima and how adjusting them can help day to day.
Even mild dehydration can worsen ocular surface dryness and burning in alacrima. Regular fluid intake helps maintain overall mucosal hydration and may reduce symptom flares.
Eating omega-3–rich foods can improve meibomian gland oil quality, helping the tear film evaporate more slowly when watery tears are scarce. This may reduce stinging and visual fluctuation.
Alcohol and high-caffeine drinks can be dehydrating and aggravate eye dryness and irritation. Limiting them or pairing with water may lessen symptom spikes.
Prolonged near work reduces blink rate, increasing evaporation and discomfort in alacrima. Scheduling frequent breaks and practicing full, deliberate blinks can improve comfort and clarity.
Risk prevention
Congenital alacrima affects tear production from birth, so the goal isn’t to prevent the condition itself but to protect the eye’s surface and avoid complications. Prevention is about lowering risk, not eliminating it completely. With steady lubrication, smart environment choices, and regular eye care, many people keep vision comfortable and the cornea healthy.
Use preservative-free artificial tears regularly to keep the eye surface moist. Thicker gels or ointments at bedtime can provide longer protection while you sleep.
Apply a lubricating ointment before bed to reduce overnight dryness. Moisture chamber goggles or a sleep mask can help hold humidity around the eyes.
Run a room humidifier and avoid direct airflow from fans, heaters, or air conditioners. Wraparound glasses or wind shields protect eyes outdoors, especially in wind or dry air.
Blink fully and take frequent breaks from screens and reading to reduce evaporation. Lowering screens slightly and avoiding drafts across the face can help people with congenital alacrima.
Transmission
Congenital alacrima is present from birth and is not contagious—you can’t catch it or pass it by contact.
In many families, especially when congenital alacrima is part of triple A (Allgrove) syndrome, it follows an autosomal recessive pattern: both parents are healthy carriers, and each pregnancy has a 25% (1 in 4) chance that a child will have the condition. In other families, congenital alacrima can be one feature of a syndrome that affects tear and salivary glands; these are often autosomal dominant, so an affected parent has a 50% (1 in 2) chance of passing it to each child. Some people have isolated congenital alacrima with no family history, caused by a new genetic change or by the tear glands not developing as expected. A genetics professional can explain how Congenital alacrima is inherited in your family and discuss the genetic transmission of Congenital alacrima.
When to test your genes
Consider genetic testing if you or a close relative had absent or greatly reduced tears from infancy, especially with feeding difficulties, poor growth, or repeated eye irritation. Testing is also reasonable before planning a family or if your clinician suspects Allgrove (triple-A) syndrome, where alacrima can pair with adrenal or swallowing problems. Results can guide eye protection, hormone monitoring, and tailored follow-up.
Diagnosis
For many, the first step comes when everyday activities start feeling harder—eyes may burn, blink more, or feel gritty, even in childhood. Congenital alacrima is often suspected when tears are absent during crying, and dry eye symptoms start early. Many people feel relief just knowing what’s really going on. The diagnosis of congenital alacrima is based on clear eye findings and is confirmed with targeted tests when needed.
Clinicians ask about dry eye symptoms from infancy, such as crying without visible tears and frequent eye irritation. Photos or videos showing a baby crying without tears can be helpful.
An eye specialist looks for dryness-related changes on the cornea and conjunctiva using a slit-lamp microscope. These clinical features support congenital alacrima when tear production is very low.
Small strips of paper are placed under the lower eyelids to measure tear production over a few minutes. Very low values point toward congenital alacrima, especially when symptoms began early in life.
Safe eye drops highlight dry spots and tiny surface damage on the cornea. The pattern helps confirm severe dryness seen in congenital alacrima and guides treatment needs.
Stages of Congenital alacrima
Congenital alacrima does not have defined progression stages. Tear production is low from birth and usually stays fairly steady, though dryness and irritation can vary with weather, screen time, and age. Doctors usually start with a conversation about symptoms and family history, then examine the eyes and measure tear production. They may also use simple office tests—like a small strip to check tear volume and a safe dye to look for surface dryness—to confirm early symptoms of congenital alacrima and guide care over time.
Outlook and prognosis
Daily routines often adapt for people living with congenital alacrima, since eyes don’t make enough tears to keep the surface moist and protected. The most common day-to-day issues are burning, gritty sensation, light sensitivity, and recurrent redness; early symptoms of congenital alacrima in babies can include poor tear production when crying and frequent eye irritation. Without steady lubrication, the clear front surface of the eye can develop tiny scratches that blur vision, and repeated injury may lead to scarring or infections. When thinking about the future, it helps to know that timely eye care and consistent tear replacement can greatly lower these risks.
Prognosis refers to how a condition tends to change or stabilize over time. Many people with congenital alacrima do well long term when they use artificial tears regularly, add thicker gels or ointments at night, and protect the eyes from wind and dry air. Some develop complications like corneal ulcers or vision loss, but these are much less likely with early treatment and follow-up. Mortality is not increased by isolated congenital alacrima itself; however, when alacrima is part of a broader syndrome—such as adrenal or nerve problems—overall health risks depend on those associated conditions.
The outlook is not the same for everyone, but regular visits with an eye specialist and, when needed, a pediatrician or endocrinologist help tailor care and catch problems early. People with congenital alacrima who also have swallowing issues, poor growth, dizziness, or skin darkening should be checked for related syndromes, because treating those can change the long-term outlook. Talk with your doctor about what your personal outlook might look like, including whether punctal plugs, moisture chamber glasses, or other options could protect your corneas and preserve vision over time.
Long-term effects
Many living with congenital alacrima face dry, irritated eyes that can affect reading, driving, or screen work from a young age. Long-term effects vary widely... Research describes the long-term effects of congenital alacrima as mainly eye-surface complications that may slowly build. In some, the condition occurs alone; in others, it appears with a broader syndrome that can involve the esophagus and adrenal glands.
Chronic dryness can injure the eye’s surface over time. This raises the risk for corneal ulcers and scarring.
Ongoing surface damage can cause fluctuating or blurred vision. In severe cases, scarring reduces how sharply you see.
Bright light may feel harsh, with stinging or burning sensations. For many, this can mean avoiding glare and windy conditions.
Reduced tear defenses increase episodes of conjunctivitis or eyelid inflammation. These bouts can leave eyes red and sore for days.
How is it to live with Congenital alacrima?
Living with congenital alacrima means your eyes don’t make enough tears from birth, so everyday things like wind, air‑conditioning, screens, and long reading can sting, blur, or feel gritty. Many people rely on a steady routine of artificial tears, gels at night, humidifiers, and protective eyewear, and they plan breaks to rest their eyes, especially during school or work. Children may rub their eyes or avoid bright light, and caregivers and teachers often help by adjusting lighting, encouraging blink breaks, and watching for signs of irritation or infection. With preparation and regular eye care, most people find a workable rhythm that protects vision and eases discomfort, and those around them can make a big difference by understanding that dryness is constant, not just occasional.
Treatment and drugs
Treatment for congenital alacrima focuses on protecting the eyes and keeping them comfortably moist, since the tear glands don’t make enough tears. Most people use preservative‑free artificial tears during the day and thicker gels or ointments at night; punctal plugs to slow tear drainage, moisture chamber glasses, and humidifiers can also help reduce irritation. Doctors sometimes add anti‑inflammatory eye drops to calm surface inflammation, and may recommend short courses of antibiotics if the eye surface shows signs of infection. Supportive care can make a real difference in how you feel day to day. Because congenital alacrima can be part of a broader syndrome, your care team may also screen for related issues—such as salivary gland dryness or adrenal problems—and tailor treatment as needed.
Non-drug treatment
Non-drug care focuses on protecting the eye’s surface, cutting down moisture loss, and making daily tasks more comfortable. Non-drug treatments often lay the foundation for day-to-day relief and help you get more from any drops your clinician recommends. Plans are tailored to how dry and irritated your eyes feel, since symptoms can swing with weather, screen use, and time of day. Early symptoms of congenital alacrima—like stinging, gritty eyes, or light sensitivity—can guide which options to start first.
Adding a room humidifier and avoiding direct fans or car vents can reduce evaporation. Simple changes at home and work often ease burning or gritty sensations. Wraparound sunglasses help outdoors in wind or cold.
These glasses form a soft seal around your eyes to trap humidity. They can make reading, cycling, or air travel more comfortable for people with congenital alacrima. Many find they cut down on frequent breaks.
Regular blinking and the 20-20-20 rule can reduce strain and dryness. Short, frequent breaks limit the long stretches where blinking slows. You may notice fewer flare-ups by adjusting screen height and glare.
Warm compresses followed by gentle lid cleaning support the oil glands that stabilize your tear film. This can slow evaporation and ease irritation. It’s a simple, daily routine many people can maintain.
Your genes may have an impact on how drugs work for you
Medicines for congenital alacrima can work differently depending on gene changes that affect tear gland structure and how receptors respond to eye drops. Because of this, some people need different doses or alternative therapies, guided by an eye specialist.
Pharmacological treatments
Congenital alacrima mainly causes severe eye dryness, so treatment focuses on protecting and hydrating the eye surface. Many families notice early symptoms of congenital alacrima—gritty, burning eyes and frequent blinking—and medicines aim to soothe the surface and prevent damage. Options range from simple lubricants to prescription drops that calm inflammation or stimulate any residual tear activity. Not everyone responds to the same medication in the same way.
Carboxymethylcellulose or hyaluronic acid artificial tears keep the surface wet and reduce burning or scratching. Preservative‑free single‑use vials are gentler for frequent daytime use.
Petrolatum–mineral oil eye ointments protect the cornea while you sleep. They can blur vision, so they are best used at bedtime.
Cyclosporine ophthalmic (Restasis, Ikervis) or lifitegrast (Xiidra) may reduce surface inflammation and help any remaining tear activity. Stinging can occur at first and usually eases over time.
Loteprednol or fluorometholone drops can calm painful flares and surface inflammation. These are used short term with eye‑pressure monitoring.
Genetic influences
People often ask whether congenital alacrima is inherited. In many children, it traces back to gene changes that disrupt how the tear glands form before birth, sometimes as part of broader syndromes such as Triple A (Allgrove) syndrome or conditions that also involve the salivary glands, teeth, ears, or fingers. Family history is one of the strongest clues to a genetic influence. This pattern often happens when each parent carries the same silent gene change, though in some families a single altered gene can be enough. Genetic testing can sometimes identify these changes and guide screening for other related issues, like adrenal problems or swallowing difficulties. When congenital alacrima appears on its own, testing may still help, but a specific gene isn’t always found, and severity can vary widely within the same family.
Is Congenital alacrima genetic?
Genetics plays a central role in congenital alacrima. Many cases result from inherited variants—often autosomal recessive—in genes affecting tear gland development or function, such as ALDH1A3 or those linked to triple-A (Allgrove) syndrome. Family history can guide testing and counseling.
Pharmacogenetics—how genetics influence drug effects
Genetic findings can shape the treatment of congenital alacrima, particularly when the condition is part of a broader syndrome such as Triple A (achalasia, alacrima, adrenal hormone problems). If testing shows this syndrome, doctors watch closely for adrenal insufficiency and swallowing issues, which can change medication plans and anesthesia needs. Most eye treatments for congenital alacrima—like lubricating drops, ointments, or prescription anti-inflammatory drops such as cyclosporine or lifitegrast—work mainly on the surface of the eye, so common drug-metabolism genes have limited impact. Not every difference in response is genetic, but your doctor can adjust the type, strength, or preservative of eye drops to find a better fit. There isn’t a routine pharmacogenetic test that predicts which dry-eye medication will work best yet, though your genetic diagnosis can still guide safety steps, like stress-dose steroids for adrenal insufficiency or avoiding medicines that can worsen dryness. When people with congenital alacrima need other medicines—for example, pain relievers after surgery or acid-reducers—genetic differences in how the body processes drugs can sometimes affect dosing, and clinicians weigh this along with age, other conditions, and the full medication list.
Interactions with other conditions
People with congenital alacrima often have eye surface problems that interact with other conditions, especially those that also dry the eyes or irritate the eyelids. Many cases occur as part of Allgrove (Triple A) syndrome, where adrenal gland issues and swallowing problems can add fatigue, weight loss, and infections that make eye care harder to keep up with; early symptoms of congenital alacrima may be missed when these other issues take center stage. A condition may “exacerbate” (make worse) symptoms of another. For example, allergies, blepharitis, or meibomian gland dysfunction can compound dryness and raise the risk of corneal scratches or infections, while respiratory infections or reflux linked with achalasia can further inflame the eyes. Autoimmune dryness such as Sjögren’s can look similar but develops later and has different immune features, so having another dry-eye condition alongside congenital alacrima calls for careful evaluation. Some medicines used for other diseases—like antihistamines, decongestants, certain antidepressants, or acne treatments—can reduce tear production further, so coordinated care helps tailor treatment and avoid stacking side effects.
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.
History
Throughout history, people have described babies who didn’t seem to cry tears, even when clearly upset or ill. Families sometimes noticed that eye redness and frequent blinking started early in childhood, and school photos showed a persistent shiny look to the eyes without tear wetness. In dry or windy weather, some children had burning or a gritty feeling that others didn’t mention. These everyday clues, collected over years, pointed to a pattern later recognized as congenital alacrima.
First described in the medical literature as a lack of tear production present from birth, early case reports focused on eye irritation and recurrent infections at the edges of the eyelids. As medical science evolved, doctors realized not all cases were the same. Some people with congenital alacrima also had trouble swallowing solid foods in childhood, faintness on standing, or growth concerns, which led researchers to connect the condition with certain nerve and gland problems in a few subtypes. Others had only dry eyes and light sensitivity. This variability shaped how the condition was recorded and studied.
From early theories to modern research, the story of congenital alacrima reflects steady progress in careful observation. In the mid to late 20th century, clinicians used simple tests—like placing a tiny strip of paper under the eyelid—to show that tear production was very low or absent. Over time, descriptions became more consistent, and eye doctors, pediatricians, and neurologists began sharing notes, which helped separate congenital alacrima from common dry eye that starts later in life.
Advances in genetics later clarified that different pathways can lead to the same day-to-day experience of “no tears.” In some families, several relatives across generations showed early symptoms of congenital alacrima, suggesting inherited forms. In others, a child was the only one affected. Researchers also learned that tear glands might be small, underdeveloped, or present but not working, and that nerve signals controlling tear production can be involved.
Despite evolving definitions, the core experience has stayed recognizable: eyes that do not water with crying and that feel dry, irritated, or sensitive to light from an early age. Knowing the condition’s history helps explain why doctors today ask about early crying, family patterns, mouth and swallowing symptoms, and faintness, and why they pair simple tear tests with targeted imaging or genetic testing when needed. This path from scattered case stories to clearer criteria has made it easier to diagnose congenital alacrima earlier, protect the eye surface, and watch for associated features when they are part of the picture.
