冇左飛蚊症都不幸???係唔係想講有左飛蚊症呀?

飛蚊症是眼內現象,症狀表現為視野看到陰影物體漂浮。這些物體可以是點狀、條狀、網狀,一個或數個一起出現。這些物體是漂浮在玻璃體當中,隨著眼球的轉動而移動,因如同蚊子在眼前飛舞,故稱之為「飛蚊症」。絕大多數的飛蚊症並不影響正常的視覺機能,但若有大量或多片黑影出現,或併發畏光、疼痛、淚水分泌過多、視野缺損等現象,或本身患有高度近視、糖尿病、高血壓等疾病,則有可能是嚴重眼疾(如視網膜剝離、玻璃體出血)的徵兆。

一旦發現,即應找眼科專科醫生鑑定。如果是良性的(如存在多年,數目沒增加且位置較固定),此類飛蚊症易在疲勞時出現,則不妨將眼球做左右或上下運動,以「避開」飛蚊之干擾。
