COLOBOMA OF THE OPTIC DISK ASSOCIATED WITH RETINAL VASCULAR ABNORMALITIES

PURPOSE: We studied a case of congenital optic disk pit and coloboma w ith associated malformations of the retinal vessels. METHODS: Slit-lam p biomicroscopy and fluorescein angiography were performed. RESULTS: M ultiple retinal venous anastomoses associated with a congenital colobo ma and pit of the optic disk were observed. The retinal vascular anoma lies extended from the optic disk to the temporal periphery. CONCLUSIO NS: We consider the coexistence of retinal venous anastomoses with opt ic disk coloboma and pit to be an extremely rare congenital retinal an omaly.
