Congenital papillary venous ring

ABSTRACT

A 31-year-old woman had an extremely rare congenital anomaly of a venous circle on her right optic disc. All of the nasal and some of the temporal retinal veins drained into this ring, which itself drained into the central retinal vein. Fluorescein angiography revealed no disturbance of vascular structure. The eye was otherwise normal with 6/6 [20/20] visual acuity and full field of vision
