A rare genetic retinal dystrophy disorder with characteristics of bilateral microcornea, rod-cone dystrophy, cataracts and posterior staphyloma, in the absence of other systemic features. Night blindness is typically the presenting manifestation and nystagmus, strabismus, astigmatism and angle closure glaucoma may be associated findings. Progressive visual acuity deterioration, due to pulverulent-like cataracts, results in poor vision ranging from no light perception to 20/400. There is evidence the disease is caused by heterozygous mutation in the bestrophin-1 gene (BEST1) on chromosome 11q12. [from
