在我国,原发性闭角型青光眼的发病率远远超过开角型青光眼。特别是慢性闭角型青光眼(以下简称慢闭),由于症状轻微,发作后又易于缓解,甚至有些病例极似开角型青光眼,因之易于疏忽或误诊。其结果可由于反复小发作而致前房角进行性器质性闭锁,进而发生视神经不可逆性损害。因而对此病的防治就有着更重要的意义。通过长期临床实践,我们体会到,早期手 In our country, the incidence of primary angle-closure glaucoma far exceeds open-angle glaucoma. In particular, chronic angle-closure glaucoma (hereinafter referred to as chronic closed), due to mild symptoms, easy to ease after the attack, and even some cases very open-angle glaucoma, it is easy to neglect or misdiagnosis. The result may be due to repeated episodes of small anterior chamber angle caused by progressive organic atresia, resulting in irreversible damage to the optic nerve. Therefore, the prevention and treatment of this disease has a more important significance. Through long-term clinical practice, we realize that early hands
