A case of sex-linked juvenile retinoschisis with peripheral vascular anomalies.

A 26-year-old man with sex-linked juvenile central and peripheral retinoschisis showed on fluorescein angiography an avascular lower temporal periphery, bordered at the central side by abnormal capillaries in a dendrite-like structure. In dominant exudative vitreoretinopathy an identical picture without schisis can be seen in the periphery. This feature seems to be a rare phenomenon in sex-linked juvenile retinoschisis. However, routine peripheral ophthalmoscopy and fluorescein angiography (especially inferotemporal) may reveal more cases.
