  • Abstract
  • Look Inside

We observed the clinical course of 18 eyes, 9 patients, with familial exudative vitreoretinopathy for periods ranging from 4 to 14 years. The present series included 6 eyes with incomplete type of FEVR with avascular peripheral retina, 8 eyes with complete type with aneurysmal dilatation of retinal vessels in the periphery and retinal exudates in addition to peripheral avascular retina, and 4 eyes with tranctional retinal detachment. One eye among 6 eyes of incomplete type progressed to complete type. Tractional retinal detachmentdeveloped in 4 out of 8 eyes of complete type of the condition.

Tractional retinal detachment was preceded by ridge-like protrusion of aneurysmal retinal vessels into the vitreous and increase in the amount of retinal exudates. We performed vitrectomy in 3 out of these 4 eyes. Retinal reattachment resulted in 2 eyes. Iris and retinal neovascularization appeared in 2 eyes after vitrectomy. Prophylactic photocoagulation to the avascular retinal area seemed to be of value in the prevention of eventual retinal detachment and neovascular reaction.
