一只小飛蟲入眼，為何會造成如此嚴重的后果？

因只蚊子男子視力僅剩0.04

醫(yī)生：這個動作=往眼里下毒

一個月前，福建莆田的周先生騎電動車下班途中，因沿途蚊蟲繁多且未佩戴頭盔，一只蚊子意外飛入左眼，他下意識用力揉眼，試圖將蚊子排出，事后并未放在心上。

A man in Putian, Fujian province, nearly lost vision in his left eye after rubbing it when a mosquito flew into his eye while he was riding an electric scooter home from work without wearing a helmet.

The incident occurred about a month ago, when Zhou was surrounded by swarms of insects. A mosquito flew into his left eye, and he instinctively rubbed it hard to remove it, thinking nothing more of the incident.

十天后，周先生左眼突發(fā)紅痛、視物模糊，還伴隨畏光、流淚等癥狀。他在當?shù)蒯t(yī)院用藥治療后收效甚微，輾轉(zhuǎn)2家醫(yī)院，最終確診為真菌性角膜潰瘍。為尋求專業(yè)的治療，他專程從福建趕往武漢專業(yè)眼科醫(yī)院。

About 10 days later, his left eye became red, painful and blurry, accompanied by light sensitivity and tearing. Initial treatment at local clinics provided little relief. After visiting two hospitals, he was diagnosed with a fungal corneal ulcer.

經(jīng)詳細檢查，周先生右眼視力0.6，左眼視力僅0.04，視物近乎不清。左眼紅腫充血、炎癥明顯，角膜邊緣有一處3毫米×3毫米的白色潰瘍病灶，角膜最薄僅270微米，表層遍布壞死組織，病情十分危急。

隨后周先生入院接受專項治療，經(jīng)過一周的救治，他的眼部不適癥狀顯著緩解，病情逐步趨于穩(wěn)定。

Further examinations showed that vision in his right eye was 0.6, while vision in his left eye had dropped to 0.04, leaving him barely able to see. Zhou was admitted to hospital for specialized treatment. After one week of care, his symptoms improved significantly and his condition stabilized.

周先生在接受治療

主治醫(yī)生曾慶延教授介紹，周先生眼部出現(xiàn)多重嚴重感染，和蚊蟲入眼后的錯誤處理方式密切相關。

異物入眼后，揉眼不僅會機械性劃傷角膜，讓蚊蟲攜帶的病原體侵入眼內(nèi)，還可能導致蟲體破裂釋放毒液，引發(fā)化學性損傷和嚴重炎癥反應，讓感染快速加重。

用力揉眼是最危險的舉動

嚴重可致盲

異物入眼后，由于異物對眼睛的刺激，大部分人會下意識地用手揉搓眼睛。但這不僅無法有效地去除異物，反而會給眼睛造成二次傷害。

當你揉眼睛時，對眼睛及其附屬器施加壓力，會導致眼部發(fā)生一系列變化，如升高眼壓、改變角膜生物力學、改變眼部微環(huán)境等，還會讓異物劃傷角膜、異物嵌入眼部組織、導致眼部感染等。

When a foreign object enters the eye, many people instinctively rub it. However, rubbing can cause further damage. Pressure on the eye may increase intraocular pressure, affect the cornea and its function, and allow the object to scratch the surface or embed in the tissue, potentially leading to serious infection.

其中，揉眼還可導致最讓人害怕的圓錐角膜。圓錐角膜是一種進行性、雙側(cè)性角膜疾病，以角膜擴張、中央變薄向前突出呈錐形為特征。它常造成近視和不規(guī)則散光，晚期可出現(xiàn)的角膜水腫和瘢痕則導致視力顯著下降，嚴重時可致盲。

揉眼很早就被確定為圓錐角膜的危險因素之一，圓錐角膜患者的第一條醫(yī)囑就是：別再揉眼！

異物入眼后的正確處理方式

醫(yī)生提醒，暮春初夏蚊蟲正值活躍期，飛蟲入眼、異物入眼的情況頻發(fā)。一旦遇到這類情況，可以這樣處理：

?禁止揉眼。

?輕輕閉眼或多次眨眼，利用眼睛自然分泌的淚液將異物沖洗排出。

?使用無菌生理鹽水或人工淚液輕輕沖洗眼睛。沖洗時輕輕轉(zhuǎn)動眼球，讓流動水帶出角膜表面的異物。（注意避免使用不潔水源導致二次感染）

? 如果這些方法都無法緩解，一定要及時到專業(yè)眼科就診，檢查有無異物殘留、眼部組織是否受損，避免小問題拖成嚴重眼疾。
