The outlook for individuals with age-related macular degeneration 2 can vary depending on the severity and progression of the condition. While it primarily affects central vision, it does not typically lead to complete blindness. Peripheral vision usually remains intact, allowing individuals to maintain some level of independence in daily activities. The progression of the condition can be slow or rapid, and it may stabilize at any stage. Regular monitoring by eye care professionals is crucial to manage the condition effectively.

There are treatments available that can help slow the progression of the disease and, in some cases, improve vision. These treatments may include medications, laser therapy, or injections into the eye. Lifestyle changes, such as a healthy diet rich in leafy greens and omega-3 fatty acids, may also support eye health. Smoking cessation is strongly advised, as smoking can accelerate the progression of the condition.

The condition does not directly affect life expectancy, as it is not associated with increased mortality. However, the vision impairment it causes can impact quality of life and may increase the risk of accidents, such as falls. Emotional and psychological support, along with vision rehabilitation services, can be beneficial in helping individuals adapt to changes in vision. Early detection and intervention are key to managing the condition effectively and maintaining the best possible quality of life.

Age-related macular degeneration 2 is primarily managed using medications that inhibit the growth of abnormal blood vessels in the eye. These medications, known as anti-VEGF drugs, include Ranibizumab, Aflibercept, Bevacizumab, and Brolucizumab. Ranibizumab and Aflibercept are injected into the eye to slow vision loss and sometimes improve vision, with treatment schedules tailored to the patient's response. Bevacizumab, originally a cancer treatment, is used off-label for this condition and offers a cost-effective alternative. Brolucizumab provides the advantage of longer intervals between injections, potentially reducing the frequency of treatments needed.
