Stargardt's disease : ウィキペディア英語版 | Stargardt disease
Stargardt disease, or fundus flavimaculatus, is an inherited form of juvenile macular degeneration that causes progressive vision loss usually to the point of legal blindness. Several genes are associated with the disorder. Symptoms, mainly vision loss, typically develop before age 20, and also include wavy vision, blind spots, blurriness, impaired color vision, and difficulty adapting to dim lighting. ==Characteristics and symptoms== The main symptom of Stargardt disease is loss of visual acuity, which ranges from 20/50 to 20/200.〔 Other symptoms include wavy vision, blind spots, blurriness, impaired color vision, and difficulty adapting to dim lighting.〔 The disease causes sensitivity to glare; overcast days offer some relief. Vision is most noticeably impaired when the macula (center of retina and focus of vision) is damaged, leaving peripheral vision more intact. Generally, vision loss starts within the first 20 years of life.
