特異な眼底を呈したTurner症候群の1症例について

A case of Turner's syndrome with unusual retinal lesions

　白内障手術を施行したTurner症候群の1症例において眼科的異常を精細に検討し，眼位，視野，暗順応，ERGの異常を認め、特に，網膜において，網膜周辺部全体にわたり，後極部を中心として，びまん性光輝小円点状白斑を輪状に認め，螢光眼底造影により，同白斑にほぼ一致して微小螢光が多数出現し，一部螢光の漏出像を認めた。

　この網膜変化は白点状網膜炎と推定し，Turner症候群の眼異常の一つとして，白点状網膜炎を加えた。

A case of Turner's syndrome showed unusual fundus features. A 62-year-old female, 119 cm in height and 25 kg in weight, sought medical ad-vice for decreased vision due to bilateral cataract, contraction of the visual field and strabismus. Physical examinations revealed webbed neck and cubitus valgus. The patient had been amenorrhoic throughout her life. ERG studies showed decreas-ed a-wave and disappearance of the oscillating potential and the b-wave. Damage in rod cells was also suggested by delay of dark adaptation and rise of the ending threshold. Her karyotype was 46 X, i (Xq), confirming the diagnosis of Turner's syndrome.
