What a Retina Specialist Does for Your Vision

Age is one of the most significant risk factors. Age-related macular degeneration (AMD), a condition that damages the central part of the retina responsible for sharp vision, is a leading cause of vision loss among older adults. People with diabetes are also at high risk. Diabetic retinopathy, a condition in which high blood sugar damages the blood vessels of the retina, affects millions of Americans and can develop without any early warning signs.

Retina specialists treat a broader range of conditions beyond AMD and diabetic eye disease. This includes people who have experienced serious eye trauma, children and adults with inherited retinal diseases such as retinitis pigmentosa or Stargardt disease, and patients with certain eye cancers including retinoblastoma in children and melanoma in adults. Anyone with a family history of retinal disease should also discuss their risk with an eye care provider.

Retina specialists are not as widely available as general eye doctors, and many patients must travel to receive care. This makes it especially important to follow through on any referral your eye doctor makes. Delaying that step can allow a condition to worsen during the waiting period.

One of the most common treatments a retina specialist performs is an intravitreal injection, which is a small injection of medication delivered directly into the vitreous cavity of the eye. These injections are used to treat conditions such as wet AMD, diabetic macular edema (DME, or swelling in the central retina caused by diabetes), and retinal vein occlusion (RVO, a blockage in the blood vessels of the retina).

Most injections use anti-VEGF medications, which block a protein called vascular endothelial growth factor. This protein causes abnormal blood vessel growth and fluid leakage in the retina. Medications in this category include aflibercept, ranibizumab, faricimab, and bevacizumab, each with its own dosing schedule. Your retina specialist will determine the right medication and treatment frequency for your specific situation. It is important to understand that anti-VEGF injections treat wet AMD and are not used for dry AMD.

Laser photocoagulation uses a focused beam of light to seal leaking blood vessels or treat damaged areas of the retina. It is commonly used in diabetic retinopathy and retinal vein occlusion. Photodynamic therapy (PDT) uses a light-activated drug that is injected into the bloodstream and then activated by a special laser aimed at the affected area of the retina, targeting abnormal blood vessels with precision.

When conditions are more advanced, surgery may be necessary. A vitrectomy is a procedure in which the vitreous gel is removed from inside the eye. This is used to treat retinal detachment, severe diabetic eye disease, macular holes, and other serious conditions. The vitreous is replaced with a gas bubble or silicone oil to help the retina heal in the correct position.

A scleral buckle places a silicone band around the outside of the eye to gently push the eye wall toward a detached retina. Pneumatic retinopexy involves injecting a gas bubble into the eye to press the retina back into place. Cryopexy, a controlled freezing treatment, is used to seal retinal tears and reduce the risk of them progressing to a full detachment.

Geographic atrophy is an advanced form of dry AMD in which retinal cells progressively break down over time. Newer medications called complement inhibitors are now approved specifically for this condition. These medications slow the progression of the disease but do not restore vision that has already been lost. Your retina specialist can explain whether this type of treatment is appropriate for your stage of disease.

For certain inherited retinal diseases, gene therapy offers a targeted approach. One approved gene therapy treats a specific genetic form of retinal dystrophy caused by mutations in the RPE65 gene. This therapy is delivered directly to the retina during a surgical procedure and represents a significant step forward for patients with this particular inherited condition.

As a general guide, symptoms that come on suddenly should always be treated as urgent. A sudden shower of new floaters, bright flashes of light, a shadow spreading across your vision, or abrupt vision loss in one eye all warrant same-day evaluation. Symptoms that have developed gradually over weeks or months are still worth reporting to your eye doctor promptly, but the urgency is different. When in doubt, calling your eye doctor right away is always the safer choice.

The eye is numbed thoroughly before any injection using anesthetic drops or a small amount of local anesthetic. Most patients describe feeling pressure or a brief sensation rather than sharp pain. Some mild soreness, redness, or a gritty feeling may occur in the hours after the procedure and usually resolves on its own within a day or two. If you are anxious about discomfort, talk with your retina specialist ahead of time so they can address your specific concerns and walk you through what to expect.

Because your pupils will be dilated during a retina visit, your vision will be blurry and your eyes will be sensitive to light for several hours afterward. You should arrange for someone to drive you home after any appointment that includes dilation. If an injection or procedure is performed, it is even more important to have a driver. Plan ahead so that transportation concerns do not become a barrier to keeping your appointments.

Many retinal conditions worsen progressively without treatment, and some of the damage that results cannot be undone. An untreated retinal detachment, for example, can cause permanent vision loss in the affected eye if not addressed quickly. Untreated diabetic retinopathy can advance to stages that are far more difficult to manage. If you have been advised to start treatment or see a specialist, following through as soon as possible gives you the best opportunity to protect your vision.

For many patients, yes. Anti-VEGF injections, laser therapy, and surgery can slow or halt progression, reduce vision loss, and in some cases improve vision. However, outcomes vary based on the specific condition, how early treatment begins, and how consistently the treatment plan is followed. Retinal diseases are often chronic, meaning they require ongoing management rather than a single cure. Newer therapies, including gene therapy for certain inherited diseases, are continuing to expand what is possible for patients.

Your regular eye doctor, whether an optometrist or a general ophthalmologist, provides broad and essential eye care including vision correction, routine exams, and screening for many conditions. A retina specialist has completed all of that foundational training plus a dedicated fellowship specifically in diseases of the retina and vitreous. This additional training means your retina specialist is equipped to perform complex procedures and interpret advanced imaging that falls outside the scope of general eye care. Think of it the way you might think of a cardiologist compared to a primary care physician.
