| 中文摘要 | 本論文報告一例典型貝氏卵黃樣黃斑變性症。患者為22歲男性,主訴半 年來視力模糊,尤其是夜間視物更加困難。經屈光矯正,其視力右眼為0.9,左 眼為0.8,眼底檢查可見左眼黃斑部表現典型黃色圓形約一個神經盤直徑大小的 卵黃囊樣變性,右眼則僅見黃斑小寫(foveal)旁有一小點黃色素沈積。螢光眼底攝 影為低螢光顯影,正符合眼底vitelliform stage的表現。色覺檢查呈現極輕微的藍 綠色區辨色不良,視野、暗適應及網膜電圖皆正常,而其眼電圖之Ardenratio,低 於正常參考值,此外,亦對其家庭成員進行眼電圖篩檢,結果檢出其父親及妹妹 皆為無症狀、眼底正常之帶因者,其Ardenratio亦低於正常參考值。 |
| 英文摘要 | A case of typical hereditary vitelliform macular dystrophy is reported. This 23-year-old male liad noticed visual deterioration, especially during the night, for about half a year. The corrected visual acuity of both eyes were 0.9 (OD) and 0.8 (OS) respectively. Ophthalmoscopic examination revealed a typical macular vitelliform lesion on the left eye, about one disc diameter in size, and a small yellowish parafoveal lesion on the right eye. The fluorescein angiography demonstrated a hypofluorescent lesion which corresponded to the fundoscopic finding. Color vision (100-Hue) test showed normal or very mild deutan-tritan defects. Dark adaptometry and visual field of both eyes were within normal limit. The ERG was normal, while the EOG, L/D ratio below 1.5, was abnormal. It is well known that Best's vitelliform macular dystrophy is an autosomal dominant disorder with variable penetrance and expressivity. In this report, we also presented his father and younger sister as asymptomatic carriers, both had normal ERG and subnormal EOG results. |
