小梁切除术是治疗开角型青光眼的首选术式。但在某些青光眼,尤其是继发性青光眼,因纤维组织增生和滤过口关闭,使小梁切除术的效果欠佳。Schocket等(1982)提出,前房植入一硅胶管,使房水流入环绕眼球的环形硅胶带的间隙,并向眶间隙弥散,以治疗新生血管性青光眼。随访59周,95%的眼压降至24mmHg以下。作者改良了Schocket植入物,治疗各种类型的顽固性青光眼51例55眼。选例及方法:患者年龄1个月～80岁(平均35.5岁)。男28、女23例。其中无晶体性青光眼15眼,新生血管性青光眼12眼,穿通性角膜移植术后9眼,先天性青光眼8眼,葡萄膜炎继发青光眼5眼,先天性无虹膜合并青光眼4眼,人工晶体眼1眼,眼外伤继发青光眼
Trabeculectomy is the first choice for the treatment of open-angle glaucoma. However, in some glaucoma, especially secondary glaucoma, due to fibrous tissue hyperplasia and filtration port closure, trabeculectomy ineffective. Schocket et al. (1982) proposed that an anterior chamber be implanted with a silicone tube to allow aqueous humor to flow into the space around the annular silicone band and diffuse into the orbital space to treat neovascular glaucoma. After 59 weeks of follow-up, 95% of intraocular pressure dropped below 24mmHg. The authors modified Schocket implants to treat 55 eyes of 51 patients with various types of intractable glaucoma. Selection and methods: Patients aged 1 month to 80 years (mean 35.5 years old). Male 28, female 23 cases. Including non-crystalline glaucoma in 15 eyes, 12 neovascular glaucoma, penetrating keratoplasty in 9 eyes, 8 eyes with congenital glaucoma, 5 eyes with secondary uveitis, 4 eyes with congenital absence of iris and glaucoma, Eye 1, eye trauma secondary to glaucoma
