Retinitis pigmentosa (RP) affects about 1 in 3,500 people worldwide. Age-related macular degeneration (AMD) affects as many as 1 in 4 people by the age of 75 and is the leading cause of blindness in people over age 50 in the United States. Both RP and AMD have a hereditary basis, and currently, there is no cure for either of these types of hereditary retinal degeneration. My clinical specialty is diagnosing and caring for patients with these diseases, using modalities from fluorescein angiography, to optical coherence tomography (OCT), to electroretinography (ERG).
