(Bietti Marginal Crystalline Dystrophy)

General: Autosomal recessive; metabolic disturbance; histopathologic studies demonstrated advanced panchorioretinal atrophy with crystals and complex lipid inclusions seen in choroidal fibroblasts.
Ocular: Marginal corneal crystalline dystrophy with retinitis punctata albescens; panchorioretinal atrophy.
Clinical: Asymptomatic.
