Basic biological effects of laser irradiation are given with respect to the treatment of chronic simple glaucoma. As for the irradiation of the trabecular meshwork, an ultrastructural analysis of what is happening in the method of Wise and Witter (1979) has been done (a). In comparison with the effect of an Argon-ion laser (pulse duration 0.2 s, pulse power 2.2 W) upon the trabecular meshwork of human autopsy eyes the effect of a Nd:YAG laser (pulse duration 10 ms, pulse energy 2 J) has been analysed in ultrastructure. After cyclodialysis by Q-switched laser pulses the routes of outflow of the aqueous humour from the suprachoroidal and supraciliary space have been marked using mercury sulfide red (b). Three ways of outflow could be identified: (1) Into the veins of the ciliary body (2) Into the vortex veins (3) Into the subarachnoidal space around the optic nerve. The last way represents a communication between the suprachoroidal space and the cerebrospinal fluid.
给出了激光照射对慢性单纯性青光眼治疗的基本生物学效应。关于小梁网的照射，已对Wise和Witter（1979年）方法中所发生的情况进行了超微结构分析（a）。与氩离子激光（脉冲持续时间0.2秒，脉冲功率2.2瓦）对人体尸眼小梁网的作用相比，已对钕钇铝石榴石激光（脉冲持续时间10毫秒，脉冲能量2焦耳）对小梁网的超微结构作用进行了分析。在用调Q激光脉冲进行睫状体分离术后，已用硫化汞红标记了房水从脉络膜上腔和睫状体上腔流出的途径（b）。可确定三种流出途径：（1）进入睫状体静脉；（2）进入涡静脉；（3）进入视神经周围的蛛网膜下腔。最后一种途径代表脉络膜上腔与脑脊液之间的连通。
