Incomplete retinal vascularization occurs in both Norrie disease and familial exudative vitreoretinopathy (FEVR). Norrin, the protein product of the Norrie disease gene, is a secreted protein of unknown biochemical function. One form of FEVR is caused by defects in Frizzled-4 (Fz4), a presumptive Wnt receptor. We show here that Norrin and Fz4 function as a… (More)

PATIENTS Two hundred and six patients with newly diagnosed neovascular AMD in one eye and pre-existing AMD in the fellow eye who were participating in a clinical trial of a psychosocial… (More)
Two brothers, one with bilateral inferotemporal retinal dialyses and the other with a unilateral inferotemporal dialysis, are described. From a review of the literature and these two cases it is concluded that when a patient with bilateral non-traumatic retinal dialyses is discovered other family members should be examined.
Two visually monocular patients with retinopathy of prematurity, followed up for 14 and 5 years, developed progressive visual loss in their twenties and thirties, respectively. In one patient, who underwent no surgery, visual acuity deteriorated from 20/30 to 20/400 over a 14-year period. The second patient had surgery for retinal detachment. Visual acuity… (More)
