伴有窄角的慢性单纯性青光眼是一种特殊病情。Romano(1968)发现这型青光眼单独使用匹罗卡品难以控制。Lowe(1966)发现这型青光眼用缩瞳药和拟交感神经药偶可发生急性闭角性青光眼。Maps-tone(1978)发现匹罗卡品和新福林试验阳性的高眼压患者,周边虹膜切除后眼压可下降。作者为研究眼压升高与匹罗卡品和浅前房的关系认为:(1)前居深度≤2.5毫米是发生闭角性青光眼的上界线。(2)虹膜切除可减轻瞳孔阻滞,使虹膜变平,前房容积增加。(3)缩瞳剂可使瞳孔阻滞程度加重。(4)前房深
Chronic simple glaucoma with narrow angle is a special condition. Romano (1968) found that this type of glaucoma is difficult to control with pilocarone alone. Lowe (1966) found that this type of glaucoma with miotic and sympathomimetic drugs can occur acute angle closure glaucoma. Maps-tone (1978) found that intraocular pressure may decrease after peripheral iridectomy in patients with elevated intraocular pressure who have been tested positive for pilocarpine and the new Forint. To study the relationship between elevated intraocular pressure and pilocarpine and shallow anterior chamber, the authors suggest that: (1) anterior depth ≤ 2.5 mm is the upper limit of closed angle glaucoma. (2) iris resection can reduce pupil block, make the iris flatten, anterior chamber volume increased. (3) miotic agent can make the degree of pupillary block worse. (4) anterior chamber deep
