青光跟滤过性手术是青光眼手术最常用的办法,其方式多种多样,但不论何种滤过术,目前都常规地制做一巩膜瓣,使手术效果更好,感染机会更少。然而巩膜瓣缝合的松紧,直接影响着术后滤过效果,亦即眼压控制的程度。缝合过紧,则术后滤过较差,眼压可再次升高;过松则滤过太畅,前房往往延缓形成或难以形 Glaucoma and filtering surgery is the most commonly used method of glaucoma surgery. There are many ways to treat glaucoma. However, no matter what type of filtering surgery, a scleral flap is routinely made so that the operation effect is better and the chance of infection is less. Scleral flap sutures, however, directly affect the effect of postoperative filtration, which is the degree of intraocular pressure control. Suture too tight, the postoperative filtration is poor, intraocular pressure can rise again; too loose filter is too smooth, the anterior chamber is often delayed or difficult to shape
