Inherited Retina Disease
Vision loss and eye diseases can often affect multiple generations of a family. Genetic factors play a role in many kinds of eye disease, including those diseases that are the leading cause of blindness among infants, children and adults. Our doctors are dedicated to early diagnosis and treatment of genetic or inherited retinal disease in Arizona.
Common Inherited Retinal Diseases
Retinal degeneration is the most common cause of inherited vision loss. Retinitis pigmentosa (RP), a condition where retinal photoreceptor cells break down and do not regenerate, affects approximately 1.5 million people worldwide. The symptoms of RP happen gradually, starting with difficulty seeing in the dark and the loss of peripheral vision.
In adults, age-related macular degeneration (AMD) is another retinal degenerative disease that appears to be inherited in a large portion of cases. AMD is the result of deterioration of the macula (the center of the retina) that causes vision loss in the center of vision.
Retinal Disease Diagnosis
A complete family and medical history as well as a comprehensive dilated exam are important first steps in diagnosing inherited retinal diseases; however, some of these conditions may be detected with a normal retinal exam. Further testing in our office is important to help make a correct diagnosis.
Retinal Disease Tests Performed
- Multifocal Electroretinogram (mfERG): Measures the electrical response from focused areas of the retina
- Visual Evoked Potential (VEP), also known as Visual Evoked Response (VER): Measures the electrical responses from the retina to the brain
- Electro-oculogram (EOG): Measures the electrical potential of the eye in a room with light and darkness
- Dark Adaptation: Measures the increasing sensitivity to dim light flashes in darkness
- Static Visual Field: Measures central visual field using a static light
- Kinetic Visual Field: Measures entire visual field using a moving light
- Color Vision Tests: Screens for inherited and acquired color vision defects
