Inherited retinal telangiectasia with glial proliferation.

We describe five patients from a family of Pakistani origin with inherited retinal telangiectasia and glial proliferation. Characteristics of this condition include: variable visual loss; peripapillary retinal telangiectasia with vascular incompetence on fluorescein angiography; glial proliferation; cystoid macular edema or altered macular pigment; retinal hemorrhage; and abnormal electroretinopathy. We discuss the similarities with and distinguishing features from other documented conditions and the mode of inheritance.
