中文摘要 | 本文報告一位典型多發閃現性白點症候群病例有持續視野盲點擴大現 象。病例為21歲中國女性,主訴左眼視力突然減退,之前有感冒病史。左眼眼學 檢查發現玻璃體細胞2度,及從黃斑部周邊到赤道部的深層網膜及色素上皮細胞 層可見境界分明的小白點。螢光血管攝影早期可見點狀的過螢光而晚期可見色素 細胞層的螢光染色。視野檢查發現左眼有明顯盲點擴大現象。網膜電圖A波及眼 電圖比率都呈低下。病人左眼視力於七週後恢復而眼病變也消失,除了視野盲點 擴大在發病六個月後仍持續存在,可能原因為視神經病變或視乳頭旁網膜病變所 致。 |
英文摘要 | This 21-year-old Chinese female suffered from acute onset blurred vision in her left eye with prodromal flu-like upper respiratory tract infection episode. There were 2+ vitreous cell and small discrete white dots in the fundus. The white dots appeared at the level of the retinal pigment epithelium and deep retina and spreaded from perimacula to equator. Early phase fluorescent angiogram showed punctate area of hyperfluorescence and the late phase showed staining of retinal pigment epithelium. Goidmann visual field showed enlargement of the blind spot in her left eye. Electrophysiologic study revealed depressed electroretinogram a-wave and electro-oculogram ratio. Laboratory examination showed increased serum level of lgG and IgA. Her visual acuity spontaneously recovered along with the eventual fading of the white dots in the fundus within seven weeks, but the patient continued to have persistent enlargement of the blind spot in her left eye six months after the onset of symptoms, which may be due to optic nerve involvement or peripapillary retinal lesion. |
