[Rosary-like abnormality of retinal veins:report of a case]

Inherited retinal venous beading is a rare autosomal dominant disorder with variable expressivity. It is characterized by irregular, segmented beading of the retinal veins. Some patients have arteriolar tortuosity. The conjunctiva can be affected by saccular vascular changes. Episodes of acute retinal vascular decompensation are also described. Low to normal leucocyte and neutrophil counts may be an extraocular associated condition. We describe the isolated case of a woman presenting retinal venous beading and conjunctival vascular aneurysms. She has no systemic anomaly and her family members examined are unaffected.
