Peripheral retinal ischemia in a young Indian woman with neurofibromatosis type 1.

Neurofibromatosis type 1 (NF-1) is an autosomal dominantly inherited disease characterized by café-au-lait spots, neurofibromas, axillary freckling, Lisch nodules of iris, gliomas and various systemic vascular ischemic manifestations mainly in the aorta, brain and kidney. Retinal vascular manifestations in patients with NF-1 are usually representative of retinal capillary hemangiomatosis. Few cases of NF-1 with retinal vascular occlusive disease have been described. We describe a young Indian woman with NF-1 with unilateral peripheral retinal ischemia but no vascular abnormality at the posterior pole.
