Coloboma of the optic disk associated with retinal vascular abnormalities.

PURPOSE

We studied a case of congenital optic disk pit and coloboma with associated malformations of the retinal vessels.

METHODS

Slit-lamp biomicroscopy and fluorescein angiography were performed.

RESULTS

Multiple retinal venous anastomoses associated with a congenital coloboma and pit of the optic disk were observed. The retinal vascular anomalies extended from the optic disk to the temporal periphery.

CONCLUSIONS

We consider the coexistence of retinal venous anastomoses with optic disk coloboma and pit to be an extremely rare congenital retinal anomaly.
