Unilateral retinal vascular disorders in a case of Turner syndrome

　片眼の網膜血管異常を伴ったターナー症候群の1例を経験した。

　症例は生後3か月の女児。在胎時に羊水染色体検査で45×0でありターナー症候群と診断された。在胎34週4日，普通分娩で出生した。ターナー症候群の全身的特徴として，高口蓋，外反肘，心房中隔欠損症がみられた。片眼の眼底耳側周辺部に無血管帯と新生血管がみられた。無血管帯に対し光凝固術を行い，新生血管は消失した。

An female infant was referred to us 4 months after birth. She was born at 34 weeks of gestation weighing 2,978g and had received oxygen at high concentration. Chromosonal analysis of the amniotic fluid showed 45XO. She showed high arched palate, cubitus valgus and atrial septal defect as manifestations of Turner syndrome. Her left fundus showed vascular area, neovascularization and multiple branchings with anastomosis of retinal vessels in the temporal periphery. The right fundus was normal. The neovasculariza-tion disappeared following retinal photocoagulation.
