冬季气候寒冷,空气湿度小,且多风雪天气,由于面部五官裸露在外,与这种不良天气直接接触的机会最多,所以容易罹患多种疾病,应注意加强预防。青光眼:青光眼是以眼内压力升高、视乳头血流灌注不良、合并视功能障碍的一种常见致盲眼病。此病分先天性、原发性和继发性三种。除先天性外,后两种均以冬季发病率最高,尤其是在强冷空气过境后24小时内最容易诱发。这是气温降幅过大,使植物神经调节功能发生紊乱而干扰了血压,造成眼压波动所致。特别是65岁以上的老人,一旦发现眼部不适伴头痛头胀,反复出现视力模糊、虹视(看灯周围有彩圈)等症状时,就应及时去医院检查。
Winter cold weather, small air humidity, and snowy weather, due to facial features exposed, the chance of direct contact with such bad weather, so prone to a variety of diseases, should pay attention to strengthening prevention. Glaucoma: Glaucoma is caused by intraocular pressure, optic nerve poor perfusion, visual dysfunction, a common cause of blindness. The disease points congenital, primary and secondary three. In addition to congenital, the latter two are the highest incidence in winter, especially in the cold air after the transition within 24 hours most likely to be induced. This is the temperature drop is too large, so that autonomic dysfunction disorders interfere with blood pressure, resulting in fluctuations in intraocular pressure. In particular, elderly people over the age of 65, once found the eye discomfort with headache, repeated blurred vision, rainbow (see the lamp around the color circle) and other symptoms, it should promptly go to the hospital for examination.
