常見眼科疾病—瞼裂斑(Pinguecula)

瞼裂斑是常見的眼部變化之一。它是一種結膜組織的增生,發生於靠近角膜的地方,以三和六點鐘方向,特別是鼻側的位置最為常見。因它為於上下眼瞼之間,所以中文名稱叫瞼裂斑。

它的顏色可以是黃白色或是透明。大多人不會因瞼裂斑而有眼睛不適的症狀,頂多是外觀上的問題。但有些患者,可能有異物感或流淚的狀況。此時可用人工淚水來潤滑治療,解除不適。有些人則在瞼裂斑周圍有結膜充血發炎的情形,此時可考慮使用類固醇藥水治療。少數突起非常明顯,或甚至妨礙隱形眼鏡配戴的患者,才會考慮手數切除病灶。

年齡愈大,瞼裂斑患者愈多。目前確切致病因未明,推測與多日照與多風的生活環境有關。另外因為工作的關係,暴露在紫外線下(譬如未戴護目鏡的焊接工人),也會促成瞼裂斑的發生。
