绝大多数的生物生活在有光的环境中。光是视器进化和发育的动力,但也可能引起视器的损伤。Schepens(1980)将与光有关的眼损伤归纳为5种类型:(1)强光;(2)强光照射于病态眼;(3)生理允许的光照量长期照射于病态眼;(4)缺乏必要的光照;(5)光照节奏异常引起的变化。其中强光引起的视网膜损伤可有三种不同的机制: (1)机械性损伤:视网膜在极短时间内接受强光照射(如高能量密度的Q-开关激光或锁模激光),由于光子冲击和组织在瞬间产热汽化,可造成机械冲击性损伤; (2)光凝性损伤:光能被组织吸收转化为热能,使局部温度升高,当超过体温10℃时,即可
Most living creatures live in a bright environment. Light is the driving force behind the evolution and development of the viewer, but it can also cause damage to the viewer. Schepens (1980) classifies light-related eye injuries into five categories: (1) glare; (2) glare on diseased eyes; (3) long-term exposure to ill-conditioned eyes for physiologically-acceptable light; (4) Lack of necessary light; (5) Changes caused by abnormal lighting rhythm. Among them, there are three different mechanisms of glaucoma-induced retinal damage: (1) mechanical damage: the retina receives strong light irradiation (such as high-energy density Q-switched laser or mode-locked laser) in a very short period of time due to photon impact And tissue heat vaporization in an instant, can cause mechanical impact damage; (2) photocoagulation damage: light absorbed by the tissue into heat, so that the local temperature, when the temperature exceeds 10 ℃, you can
