A few days ago, the success of several members of the Chinese Mount Everest climbing team on the summit of Mount Everest was encouraging, but several members of the team experienced snow blindness in the climb.
What is snow blindness? The reporter interviewed Zheng Yuanyuan, director of Beijing Municipal Office of Prevention of Blindness and Associate Researcher of Beijing Eye Institute. Zheng Yuanyuan said that snow blindness is electro-optic ophthalmia, which is mainly caused by inflammation of the cornea and conjunctival epithelium caused by ultraviolet rays. It is characterized by eyelid swelling, conjunctival hyperemia and edema, and severe foreign body sensation and pain. Symptoms include photophobia, tearing, and blindness. During the onset of illness, there may be blurred vision. The members of Deng Zhufeng who suffer from snow blindness are caused by strong ultraviolet radiation in mountain climbing. The air in the mountains is thin, and the ultraviolet rays are very strong. Coupled with the reflection of snow, if it is not protected properly, snow blindness can easily occur. In addition, ultraviolet radiation damage to the eyes can be caused by industrial electric welding, plateaus, snow, and surface reflections. In particular, prevention and treatment of SARS nowadays often use UV disinfection methods in public places. Working and studying under ultraviolet light for a long time can lead to snow blindness. So don't stay or look at things for a long time under intense UV light. The electro-optic ophthalmia can be restored under normal circumstances. It will not affect vision after the condition improves. Zheng Yuanyuan said that after the appearance of snow blindness, it should try to avoid the stimulation of light, pay attention to rest, can generally heal within 48 hours, and sometimes can even cure self-healing.
In terms of clinical treatment, the first is symptomatic treatment. The pain is given to the eyes of anesthetic drugs and drugs that promote corneal repair are used. If the medical conditions do not allow, you can also find some breast milk drops, the same can play a role in pain relief. (health)
