摘要

目的：本文主要報告先天穩定型夜盲症患者，其電氣生理檢查典型的發現。
方法：病例報告。
結果：20歲男性，主訴自幼夜盲。眼底檢查及眼底螢光攝影檢查呈近視性退化，光適應視網膜電圖正常，暗適應視網膜電圖及暗適應檢查異常。診斷為先天穩定型夜盲症。結論：在臨床上常會遇到夜盲的病人，造成夜盲的原因很多。為了鑑別診斷夜盲症，除了眼底檢查外，尚可使用電氣生理檢查來分辨是何種類型的疾病。

Congenital stationary night blindness is a disorder of rod function or neural transmission under scotopic condition. We presented a 20-year-old male suffering from night blindness since childhood. His best corrected visual acuity was 20/25 of the right eye and 20/33 of the left eye. The slit-lamp biomicroscopy showed no positive findings and fundus was normal in ophthal-moscopy and fluorescein angiography. The photoptic ERG was normal and the dark-adapted light flash ERG revealed a deep a-wave with a reduced b-wave. The EOG ratio and the dark-adaptation test were abnormal. Several members of this family also have the same problem. The clinical manifestation and diagnosis of congenital stationary night blindness was discussed.
