Retinal angioma and juvenile sex-linked retinoschisis.

A 13-year-old boy presented with juvenile X-linked retinoschisis and in the right fundus a typical retinal angioma situated at the temporal site of the macula. A maternal uncle and a maternal grand uncle were known to be also affected by juvenile retinoschisis. Family history was negative for retinal angiomatosis. Extensive internal, neurologic and radiologic examinations did not reveal associated neurologic or visceral involvement in the affected child. The association of a retinal angioma and juvenile X-linked retinoschisis is most probably fortuitous.
