Two cases of unilateral retinal neovascularization in Turner syndrome.

Abstract

To report two cases of unilateral retinal neovascularization in Turner syndrome. We examined two female infants, born at 34 weeks' and 33 weeks' gestation, who had received oxygen for 9 days and 3 days, respectively, after birth. Both infants had the 45,XO karyotype of Turner syndrome. In each patient, the fundus of one eye showed an avascular area, neovascularization, and multiple branchings with anastomosis of retinal vessels in the temporal periphery. Fellow eyes showed no abnormalities in the fundi. Both infants were treated with argon laser photocoagulation to the avascular area and the neovascularization in the temporal periphery. The neovascularization regressed completely after retinal photocoagulation. Abnormalities of retinal vessels may be one of the ocular findings associated with Turner syndrome.
