Optic disc drusen may be accompanied by an unusual branching of vessels on the optic disc and in the adjacent retina. The early influence of congenital drusen on the developing vascular system during the embryonic phase seems to be responsible for this.1 We describe a patient with bilateral optic disc drusen who had 2 anastomoses between cilio-retinal and retinal arteries, venovenous communications, and a macular aneurysm in her right eye.

Report of a Case.  A 16-year-old girl with known drusen of both papillae had an esotropia of the left eye since the age of 4 years, which changed into an esotropia of the right eye 2 years ago. The reason was a deterioration of visual acuity to 1/7.5 OD owing to a largely thrombosed retinal aneurysm with macular edema (Figure 1). Five years ago visual acuity had been 20/25 OU.
