Disc edge veins of Kraupa associated with optic disc drusen.
OBJECTIVE
Disc edge veins of Kraupa are a rare anomaly of the retinal venous system in which the main trunk of the retinal vein disappeared into the margin of the optic disc instead of its centre.


METHODS
A 40-year-old woman was detected to have an anomaly in her left optic disc in a routine eye examination. The eyes had an anomaly of the retinal venous system in which all branches of the retinal vein joined in a common trunk that entered the disc margin inferonasally. The central retinal artery issued from the centre of the disc separately of the venous system. B-scan ultrasonografhy revealed the presence of hyperechoic imaging at the optic nerve head in both eyes.


RESULTS
We describe the association of disc edge veins of Kraupa with optic disc drusen.


CONCLUSIONS
Vascular complications of optic disc drusen hav been described. We don't know the implication of disc edge veins in the pathogenesis of these complications.
