由于巩膜瘢痕的形成,青光眼滤过术常在术后数月内失败。有的滤过泡从未形成,其它罕见的原因是内外滤口被增生膜堵塞。作者对9例术后被膜状物及色素堵塞的滤口,采用Nd-YAG激光击射。 9例中,男性5人,女性4人,年龄25～80岁。右眼5眼,左眼4眼。无晶体眼1眼。植入人工晶体3眼(前房型1例,后房型2例)。行滤过术时间为1个月～26年。5例行小梁切除,4例行巩膜咬切术。房角镜检查,9眼滤口均为色素膜、玻璃体及晶体囊物质堵塞。在房角镜配
Glaucoma filtration often fails within months after surgery due to scleral scarring. Some filtering bleb has never formed, the other rare reason is that the filter inside and outside the plugging by the accretion membrane. The authors of nine cases were blocked by the film material and pigment filter, the use of Nd-YAG laser shot. 9 cases, 5 males and 4 females, aged 25 to 80 years. Right eye 5 eyes, left eye 4 eyes. Aphakia eyes 1 eye. Implantation of intraocular lens 3 (anterior chamber in 1 case, posterior chamber in 2 cases). Line filtration surgery time of 1 month to 26 years. 5 cases of trabeculectomy, 4 cases of scleral bite resection. Gonocular examination, 9 eye filters are pigment film, vitreous and crystalline capsule material blockage. Mirror in the corner
