Figure 1.

Classic features of FEVR

1A. Fundus fluorescein angiogram showing the temporal retinal periphery of the right eye of a mildly affected person. Black areas to the left of the photograph represent loss of the normal capillary architecture corresponding to a region of retinal avascularity. Adjacent to this are dilated truncated telangictatic vessels leaking fluorescein dye (white patches). On the right of the photograph preserved retinal vessels are straightened as they approach the avascular zone.

1B. Fundus photograph of the right eye from an individual with more severe disease. Extensive vitreoretinal traction distorts the retinal vessels emerging from the optic disc, producing a retinal fold extending across the posterior pole to the temporal periphery.
