一男子骑车时因蚊子突然飞入眼中，下意识揉了揉眼。他怎么也没想到，这个再平常不过的动作竟让他险些失去视力。

一只小飞虫入眼，为何会造成如此严重的后果？

因只蚊子男子视力仅剩0.04

医生：这个动作=往眼里下毒

一个月前，福建莆田的周先生骑电动车下班途中，因沿途蚊虫繁多且未佩戴头盔，一只蚊子意外飞入左眼，他下意识用力揉眼，试图将蚊子排出，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，周先生左眼突发红痛、视物模糊，还伴随畏光、流泪等症状。他在当地医院用药治疗后收效甚微，辗转2家医院，最终确诊为真菌性角膜溃疡。为寻求专业的治疗，他专程从福建赶往武汉专业眼科医院。

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.

经详细检查，周先生右眼视力0.6，左眼视力仅0.04，视物近乎不清。左眼红肿充血、炎症明显，角膜边缘有一处3毫米×3毫米的白色溃疡病灶，角膜最薄仅270微米，表层遍布坏死组织，病情十分危急。

随后周先生入院接受专项治疗，经过一周的救治，他的眼部不适症状显著缓解，病情逐步趋于稳定。

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.



周先生在接受治疗

主治医生曾庆延教授介绍，周先生眼部出现多重严重感染，和蚊虫入眼后的错误处理方式密切相关。

异物入眼后，揉眼不仅会机械性划伤角膜，让蚊虫携带的病原体侵入眼内，还可能导致虫体破裂释放毒液，引发化学性损伤和严重炎症反应，让感染快速加重。

用力揉眼是最危险的举动

严重可致盲

异物入眼后，由于异物对眼睛的刺激，大部分人会下意识地用手揉搓眼睛。但这不仅无法有效地去除异物，反而会给眼睛造成二次伤害。

当你揉眼睛时，对眼睛及其附属器施加压力，会导致眼部发生一系列变化，如升高眼压、改变角膜生物力学、改变眼部微环境等，还会让异物划伤角膜、异物嵌入眼部组织、导致眼部感染等。

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，揉眼还可导致最让人害怕的圆锥角膜。圆锥角膜是一种进行性、双侧性角膜疾病，以角膜扩张、中央变薄向前突出呈锥形为特征。它常造成近视和不规则散光，晚期可出现的角膜水肿和瘢痕则导致视力显著下降，严重时可致盲。



揉眼很早就被确定为圆锥角膜的危险因素之一，圆锥角膜患者的第一条医嘱就是：别再揉眼！

异物入眼后的正确处理方式

医生提醒，暮春初夏蚊虫正值活跃期，飞虫入眼、异物入眼的情况频发。一旦遇到这类情况，可以这样处理：

❶ 禁止揉眼。

❷ 轻轻闭眼或多次眨眼，利用眼睛自然分泌的泪液将异物冲洗排出。

❸ 使用无菌生理盐水或人工泪液轻轻冲洗眼睛。冲洗时轻轻转动眼球，让流动水带出角膜表面的异物。（注意避免使用不洁水源导致二次感染）



❹ 如果这些方法都无法缓解，一定要及时到专业眼科就诊，检查有无异物残留、眼部组织是否受损，避免小问题拖成严重眼疾。
