抗青光眼手术方法多种,各有其优缺点。自一九六八年Cairns介绍小梁切除术以来,国内不少学者报道以此手术疗效较高,也有不少报道在此基础上的改良术式,如活辨式小梁切除术等。小梁切除术具有内外引流的特点,控制眼压近期疗效是肯定的,国外报道为70.23％—100％,国内报道也在90％以上,是近代抗青光眼手术中较为理想手术,但远期疗效仍不很满意。小梁切除术后,如果不用降压药物而眼压稳定在2.50kpa以下,则视野可不致继续受损,否则有些病例需辅助药物治疗,或再次手术。术后眼压升高的主要原因是滤泡的瘢痕化和手术滤过口闭塞。为使小粱切除术后形成良好的滤过泡和滤过口开放,Alpar在一九八六年报道在手术滤过道区充填
A variety of anti-glaucoma surgery, each with its advantages and disadvantages. Since introduction of trabecular surgery in Cairns in 1968, many domestic scholars have reported that this surgery has a high therapeutic effect. There are also many reports on this basis, such as live-resolution trabeculectomy. Trabeculectomy has the characteristics of internal and external drainage, the control of intraocular pressure in the near future is positive, reported 70.23% -100% in foreign countries, the domestic coverage of more than 90%, is an ideal anti-glaucoma surgery in modern surgery, but long-term efficacy Still not very satisfied. After trabeculectomy, if you do not use antihypertensive drugs and intraocular pressure stabilized at 2.50kpa below, the visual field may not continue to be damaged, or in some cases need adjuvant drug therapy, or reoperation. Postoperative intraocular pressure is mainly due to increased scarring of the follicles and surgical filtration occlusion of the mouth. In order to create a good filter bleb after the removal of sorghum and the opening of the filter opening, Alpar reported in 1986 that in the area of surgical filtration of the fill area
