Retinitis Pigmentosa & Inherited Retinal Diseases

One of the earliest and most common symptoms is difficulty seeing in low light conditions. You might notice trouble walking in dimly lit restaurants, navigating your home at night, or adjusting when moving from bright to dark areas. This happens because RP typically affects rod cells first, which are crucial for night vision. Many patients describe feeling like they need much more light than other people to see clearly.

Many people with RP develop tunnel vision as their side vision gradually decreases. You might bump into objects on your sides, have trouble seeing cars approaching from the side while driving, or feel like you're looking through a narrow tunnel. This symptom often progresses slowly over many years, and some people adapt so well that they don't notice the change until it becomes more advanced.

Light sensitivity and problems with glare are common symptoms that can significantly impact daily life. You might find bright sunlight uncomfortable, have trouble seeing when car headlights shine toward you, or notice halos around lights. These issues can make driving at night particularly challenging and may require special sunglasses or other protective measures.

Some people with RP notice changes in how they see colors, especially blues and greens. Colors might appear less bright or harder to tell apart from one another. This symptom is more noticeable in advanced stages of the disease or in certain types of IRDs that mainly affect cone cells.

While RP typically affects side vision first, some people may experience central vision problems in later stages. This can make reading, recognizing faces, and doing detailed tasks more difficult. The timing and severity of central vision changes vary greatly between individuals. Most people maintain central reading vision until later stages, but central blur can occur if complications develop.

Some people notice shimmering lights, flashes, or increased floaters. While often harmless, new or sudden symptoms should be checked to rule out retinal tears or other treatable issues. These visual disturbances can be part of the disease process but should always be evaluated by your eye doctor.

Common complications include cataracts that increase glare and blur, and swelling in the center of the retina that reduces central clarity. Both of these complications are treatable and can improve your vision function when properly managed by your retina specialist.

Current evidence does not support routine vitamin A supplementation for slowing RP progression, and high-dose vitamin E may be harmful and should be avoided. Supplementation should not be used as disease-modifying therapy outside individualized medical advice, especially in pregnancy, liver disease, or other risk contexts. Our doctors will discuss whether any specific nutritional approaches might be appropriate for your individual situation.

At present, the only FDA-approved gene therapy for IRDs is Luxturna for RPE65-related disease, which applies to a specific subset of patients with Leber congenital amaurosis. For RP, multiple genotype-specific and gene-agnostic approaches are in late-stage development, including optogenetic therapies and modifier gene treatments currently in clinical trials. Our team stays current with the latest advances and can help determine if you might be a candidate for investigational treatments.

For RP-associated cystoid macular edema, carbonic anhydrase inhibitors such as oral acetazolamide or topical dorzolamide are first-line treatments, with steroids considered selectively. Anti-VEGF injections have limited benefit in this setting unless another indication exists. Cataracts that reduce vision can be managed with surgery, with careful planning to protect your delicate retina.

Commercial retinal prostheses like Argus II are no longer available, and there is currently no commercially available retinal implant for RP. Current work in prosthetics, cortical devices, and optogenetics is investigational and accessed primarily via clinical trials or select research centers. These technologies continue to advance and may offer future options for patients with advanced vision loss.

Various devices and technologies can help maximize your remaining vision and maintain independence:

• Magnifying glasses and electronic magnifiers for reading and close work
• Telescopic lenses for distance vision and watching television
• Task lighting, contrast enhancement, and glare-reducing filters for improved comfort
• Smartphone apps that can read text aloud and identify objects
• Computer software that enlarges text and converts text to speech
• Specialized lighting solutions for home and work environments
• Wearable displays and contrast-enhancing filters

Protecting your remaining vision is crucial for maintaining function as long as possible. We recommend wearing UV-protective sunglasses and wide-brimmed hats when outdoors, avoiding excessive bright light exposure, and maintaining regular eye exams to monitor for other eye conditions. Some patients benefit from specially tinted lenses that reduce glare and improve comfort.

Participating in clinical trials gives you access to cutting-edge treatments before they become widely available. Our practice maintains connections with leading research institutions and can help you learn about appropriate clinical trial opportunities. Active areas include optogenetic therapies, gene therapies for specific mutations, cell protection strategies, and devices that enhance remaining vision. Eligibility depends on genetics and disease stage.

Genetic counselors help interpret test results, discuss reproductive options, and support relatives who may wish to test. This ensures informed decisions for families across generations and helps clarify risks for future children.
