Diagnostic ConsiderationsAutosomal-recessive bestrophinopathy

Autosomal-recessive bestrophinopathy results from a homozygous or compound heterozygous BEST1 mutation. The age of onset is between 4 and 40 years, and the condition results in vision deterioration to below 20/70 within a few years. Fundus examination reveals irregular RPE and white subretinal deposits in the macula and midperiphery. Affected individuals may not have vitelliform lesions. EOG is severely reduced, and the pattern ERG is markedly abnormal. [15]
