Familial cavitary optic disc anomaly

A rare genetic eye disease characterized by congenital profound excavation of the optic nerve head with diminished visual field, in the absence of elevated intraocular pressure. Many patients lack a well-formed retinal artery and have multiple radial cilioretinal arteries instead. The condition is mostly bilateral, may worsen progressively, and is often complicated by serous macular detachment with profound visual loss.
