Protect Against Progressive Vision Loss

The retina is a thin, light-sensitive layer lining the back of your eye that converts light into electrical signals, which are transmitted to your brain through the optic nerve. Within the retina, specialized photoreceptor cells called rods and cones detect dim light, color, and fine detail. These cells rely on hundreds of genes to produce proteins that support normal retinal development, function, and long-term cell survival.

Inherited retinal degenerations are a group of genetic eye disorders caused by mutations in these critical genes. The faulty genes gradually damage photoreceptors or other retinal cells, disrupting how visual information is processed. Depending on the specific condition, this may lead to night blindness, peripheral vision loss, reduced central vision, color vision changes, or progressive vision impairment over time.

What Are the Benefits of Treatment for Inherited Retinal Degeneration?

Although many inherited retinal degenerations cannot be cured, early diagnosis and specialized management can help preserve vision, monitor disease progression, and identify opportunities for advanced therapies. Treatment may offer several important benefits, including:

  • Earlier detection of disease progression
  • Preservation of remaining retinal function
  • Access to advanced imaging and genetic testing
  • Improved management of vision-related symptoms
  • Ongoing monitoring to protect long-term eye health
  • Better planning for future visual needs and rehabilitation

Do I Have Inherited Retinal Degenerations?

Inherited retinal degenerations often develop gradually, making early symptoms easy to overlook. If you have noticed changes in your vision, especially if they worsen over time or run in your family, a comprehensive retinal evaluation can help determine the underlying cause. You may benefit from an evaluation if:

  • You experience difficulty seeing in dim light or at night
  • You notice a gradual loss of your peripheral (side) vision
  • You have blurred central vision that continues to worsen
  • You struggle to distinguish colors or notice reduced color perception
  • You see persistent blind spots or areas of missing vision
  • You have a family history of inherited retinal diseases
  • You experience progressive vision changes without another identifiable eye condition
  • You have been diagnosed with conditions such as retinitis pigmentosa, Stargardt disease, cone-rod dystrophy, Leber congenital amaurosis, or other inherited retinal disorders

At The Vision Institute, we use advanced retinal imaging, OCT imaging, ultra-wide-angle fundus photography, functional vision testing, and, when appropriate, genetic testing to diagnose inherited retinal degenerations. This allows our specialists to identify the specific condition affecting your retina and develop a personalized long-term management plan.

What Are Common Inherited Retinal Degenerations?

Retinitis Pigmentosa

Retinitis pigmentosa is the most common inherited retinal degeneration. It primarily affects rod photoreceptor cells, causing night blindness and progressive peripheral vision loss, and may eventually reduce central vision as the disease advances.

Stargardt Disease

Stargardt disease is an inherited macular disorder that affects central vision. It causes fatty material to accumulate beneath the retina, damaging cone photoreceptors responsible for reading, recognizing faces, and seeing fine detail.

Cone-Rod Dystrophy

Cone-rod dystrophy typically affects cone photoreceptors before rods. You may first notice blurred central vision, reduced color perception, and sensitivity to bright light, followed by a gradual decline in peripheral and night vision over time.

Leber Congenital Amaurosis

Leber congenital amaurosis is a rare inherited retinal disease present at birth or in early infancy. Severe dysfunction of retinal photoreceptors leads to significant visual impairment, involuntary eye movements, and delayed visual development.

Choroideremia

Choroideremia is a genetic disorder that primarily affects males and leads to the gradual degeneration of the retina, retinal pigment epithelium, and choroid. Choroideremia symptoms often begin with night blindness, then progress to peripheral and central vision loss.

Inherited Retinal Degenerations Frequently Asked Questions

Can inherited retinal degenerations be cured?

Most inherited retinal degenerations cannot currently be cured, but treatment options continue to advance. Depending on your diagnosis, management may help preserve vision, slow disease progression, treat complications, and improve quality of life.

Are inherited retinal degenerations always hereditary?

Yes. These conditions result from genetic mutations that are passed through families or occur as new genetic changes. However, you may not know of a family history because some inheritance patterns can skip generations or cause symptoms that vary between relatives.

Will I eventually lose all of my vision?

Not necessarily. Every inherited retinal degeneration progresses differently. Some primarily affect peripheral vision, while others mainly impact central vision. Your outlook depends on the specific genetic condition, the severity of retinal damage, and how early it is diagnosed. Regular monitoring allows your specialist to track changes and recommend appropriate interventions.

Do I need genetic testing?

Genetic testing is often recommended because it helps identify the exact mutation responsible for your condition. This information can confirm your diagnosis, guide long-term management, determine eligibility for emerging treatments or gene therapies, and provide valuable information for family members who may also be at risk.

Are there risks if inherited retinal degeneration goes untreated?

Yes. Without ongoing monitoring, progressive retinal damage may continue unnoticed, leading to worsening vision loss and delayed identification of complications or treatment opportunities. While treatment cannot always stop disease progression, regular evaluations allow your specialist to preserve as much vision as possible.
