BESTS DISEASE: A CASE REPORT

Bests disease is an autosomal dominant hereditary macular dystrophy characterized by the presence of auto-fluorescent vitelline deposits. We report a case of a vitelliform stage of bests disease in a 23-year-old female patient. The diagnosis was made based on the fundus appearance: egg yolk macular lesion, hypofluorescence in the early stages, OCT appearance and alteration of the electro-oculogram and the electroretinogram. The exact frequency of this condition is difficult to determine and varies according to the various studies. It is thought to account for 4% of all retinal dystrophies. Its management is an annual surveillance.
