The genetic eye disease Retinitis Pigmentosa is the primary pigmentary retinal dystrophy is a hereditary disorder. Retinitis pigmentosa is relatively rare, affecting 1 in 3,700 people. The cause is one of a host of over 100 different genetic mutations. The problem may lie with the genes that affect rod and cone photoreceptors, particularly the rods essential for side and night vision. The disease can also manifest as retinal pigment epithelium mutations or abnormalities in the retina. Symptoms include gradual vision loss, poor adaptation to light changes, and difficulty seeing at night. Patients may also have limited peripheral vision and certain types of colour blindness.
Treatment options for this eye disease are limited. Measures to stop progression (Light exclusion therapy, ultrasonic therapy & acupuncture therapy), correctany refractive error, give low vision aids (magnifying glasses, night vision device), rehabilitation, Prophylaxis(genetic counselling for no consanguineous marriages).
Genetic eye diseases, including Fuch’s Corneal Dystrophy, Leber’s Hereditary Optic Neuropathy, and Leber Congenital Amaurosis. The majority of eye diseases, such as cataracts, macular degeneration, and glaucoma, are influenced more by lifestyle than any genetic predisposition.
