What Should Seniors Know About Eye Injections for Macular Degeneration?
Eye injections have revolutionized treatment for wet age-related macular degeneration and other retinal conditions. While the idea of eye injections sounds frightening, understanding the procedure helps seniors approach this vision-saving treatment with less anxiety.
Why Eye Injections Are Used
Wet macular degeneration involves abnormal blood vessel growth beneath the retina. These vessels leak fluid and blood, damaging the macula and causing central vision loss. Without treatment, vision deteriorates significantly.
Anti-VEGF medications stop abnormal blood vessel growth and leakage. Injected directly into the eye, these medications reach the retina at high concentrations. Regular treatment can stabilize vision and sometimes improve it.
Other conditions treated with eye injections include diabetic macular edema, retinal vein occlusions, and other causes of abnormal retinal blood vessels or swelling.
What to Expect
The procedure is performed in the ophthalmologist’s office. The eye is numbed with drops or gel, eliminating pain sensation. The eye surface is cleaned with antiseptic solution. A small speculum holds the eyelids open.
The injection itself takes only seconds. A very fine needle passes through the white of the eye into the vitreous cavity. Most patients report feeling pressure but not significant pain. The needle is too small to see during the procedure.
Afterward, the eye may feel slightly irritated, gritty, or watery. These sensations typically resolve within a day. Mild redness at the injection site is normal. Eye drops may be prescribed to prevent infection.
Treatment Schedule
Initial treatment typically involves monthly injections for several months. As the condition stabilizes, injection frequency may decrease. Some patients eventually need injections only every few months.
Treatment is ongoing for most patients. Stopping treatment usually leads to recurrence of fluid leakage and vision loss. Commitment to the treatment schedule is essential for maintaining vision.
Regular monitoring through imaging and vision testing guides treatment decisions. Your ophthalmologist adjusts the schedule based on how your eye responds.
Effectiveness
Anti-VEGF treatment has transformed macular degeneration outcomes. Most patients maintain their vision with treatment. About one-third experience vision improvement. Before these treatments, wet macular degeneration typically led to significant vision loss.
Early treatment produces better outcomes. Prompt evaluation of vision changes enables treatment before significant damage occurs.
Risks
Serious complications are rare but possible. Infection inside the eye, called endophthalmitis, is the most serious risk, occurring in less than 1 in 1,000 injections. Retinal detachment can occur rarely. Increased eye pressure sometimes develops.
Minor side effects include temporary floaters, eye redness, and mild discomfort. These typically resolve quickly without intervention.
Managing Anxiety
Fear of eye injections is understandable. Knowing that the eye is numbed and the procedure is brief helps reduce anxiety. Most patients report the anticipation is worse than the actual injection. Regular patients often become comfortable with the procedure.
