Best disease (Best vitelliform macular dystrophy, BVMD) is a rare autosomal dominant disorder due to the mutation of BEST1 (or VMD2, TU15B ...) gene with incomplete penetrance and variable expression which typically presents in childhood. However, there are also reports of autosomal recessive BVMD. Its characteristic presentation is by bilateral fundus changes of egg-yolk appearance (as in a fried egg with sunny side up) at the macula in both eyes. The retinal pigment epithelium (RPE) is primarily affected. ... The visual prognosis of the disease is usually good, usually maintaining driving/reading capability in at least one eye throughout life.

L'aspect du fond d'œil ressemble à un œuf sur le plat [...]
