飛蚊症

 

飛蚊症是常見的眼科問題,患者一般見到有點狀或條索狀飄浮物於眼前飄動,可以單眼或雙眼同時發病、形狀不同,常會有視覺障礙。雖然這是一個常見症狀,但亦可以是"玻璃體後脫離"症狀 ,如遇上此情況,必須作詳細眼底檢查,因"玻璃體後脫有較大機會引起視網膜脫落。

大多數患者出現飛蚊症,原因多由於玻璃體退化,玻璃體位於晶狀體與視網膜之間,如它退化變成混濁,光線經過它時則使混濁物的影像投射於視網膜上,使病者見到不同形狀的飛蚊,更阻礙視覺。

如突然發現飛蚊增多甚至見到閃光,則可以是玻璃體脫離或視網膜脫落等症狀,前者亦可引致視網膜脫落。所以患者必須作眼科檢查,以確定是否患有視網膜退化或脫落等病變。

飛蚊症可利用中醫眼科方法治療,中醫眼科病名為"雲霧移睛"。病因多由於勞累、用眼過度晚睡或休息不足等。

進行中醫四診後,醫師會根據四診資料進行辨證分析,並定下治療方案而進行治療。
