小梁切除联合周边虹膜嵌顿术的临床分析 总被引:2,自引:1,他引:1
目的为了提高青光眼手术的成功率,将小梁切除术加以改进,即小梁切除联合周边虹膜嵌顿术(TI二联术)。方法87例103只眼行TI二联术,对照组小梁切除术163例168只眼,观察比较术后眼压、视力。结果闭角型青光眼TI二联术手术成功率为96.55%,小梁切除术成功率85.27%,有显著差异。对于开角型青光眼,两种手术方法的成功率均为75%~76%。结论原发性闭角型青光眼TI二联术手术成功率明显高于小梁切除术,但对于原发性开角型青光眼,两种术式成功率相似。 相似文献

急性闭角型青光眼小梁切除术后角膜内皮形态研究 总被引:6,自引:0,他引:6
为探讨急性原发性闭角型青光眼(PACG)及其小梁切除术后角膜内皮细胞(CEC)的形态计量学变化和临床意义。对36例PACG患者于小梁切除术前和术后3个月进行了角膜内皮细胞观察和图象分析。结果:与正常人相比,PACG患者CEC密度、形状系数明显减小,面积、周长、长径、变异系数增大(P<0.01)。无并发症的小梁切除术未使CEC发生形态计量学变化。而术后浅前房者与术前相比CEC密度和形状系数进一步减小。面积、周长、长径和变异系数进一步增大。结论:PACG患者CEC处于不稳定状态,应尽早控制眼压,在选择小梁切除术时防治术后浅前房对保护CEC十分重要 相似文献

Purpose:To investigate the safety and efficacy of combined trabeculectomy for primary acute angle closure glaucoma with persistent ocular hypertension.Methods:A total of 36 patients (40 eyes) with primary acute angle closure glaucoma,who were treated with combined trabeculectomy in the Ophthalmology Unit of our hospital,were selected.Before the procedure,patients were assigned to ocular hypertension group( ≥ 40 mm Hg) or control group(< 40 mm Hg) based on intraocular pressure.These two groups were followed up for one year,and compared for post-operative visual acuity,intraocular pressure, filtering bleb,anterior chamber depth, and the occurrence of complications.Results:At 1 week,6 months,and 12 months after the procedure,intraocular pressure was controlled in both the ocular hypertension group and the control group,without significant differences between the two groups (P>0.05).At 1 week,6 months,and 12 months after the procedure,all of the patients,in both groups,had improved in terms of visual acuity,with a significant difference before and after the procedure for the ocular hypertension group (P<0.05).After follow-up at 12 months,the two groups presented no statistically significant differences in anterior chamber depth,filtering bleb survival,or the incidence of post-operative complications (P>0.05 for all).Conclusion:It is feasible,safe,and effective to perform combined trabeculectomy on patients with primary acute angle closure glaucoma complicated by persistent ocular hypertension. 相似文献

PURPOSE: To compare the results of small incision trabeculectomy avoiding Tenon's capsule (SIT) vis-à-vis intraoperative use of Mitomycin-C (MMC) in primary chronic angle closure glaucoma. METHODS: A controlled prospective study was conducted on 60 consecutive primary chronic angle closure glaucoma patients requiring glaucoma filtration surgery. Patients were divided into two groups, Group I (n = 30): those undergoing SIT and Group II (n = 30): those undergoing trabeculectomy with MMC. Patients were followed up serially for 24 months and their intraocular pressure (IOP) was monitored. Success was defined as IOP < or = 22 mm Hg with no additional anti-glaucoma medication or laser/surgical intervention. Success was also defined as a 30% reduction from the initial IOP at which optic disc cupping and/or visual field changes occurred. RESULTS: The final mean IOP with SIT was 16.80 +/- 4.20 mm Hg as against 17.84 +/- 3.80 mm Hg with trabeculectomy with MMC. Final success rate of 93.3% was obtained with SIT versus 90% with trabeculectomy with MMC. No major complications were seen with either procedure. CONCLUSION: Small incision trabeculectomy safely and effectively reduces the IOP in over 90% cases. The advantages of this procedure over trabeculectomy with MMC are its low cost, use of a small (2.5 mm) limbal incision which obviates the dissection of Tenon's capsule and absence of any major complication. 相似文献

目的:观察复合式小梁切除加前房注射过滤空气治疗原发性慢性闭角型青光眼的临床疗效及手术的安全性和有效性。
方法:将2015-09/2017-06在我院收治的原发性慢性闭角型青光眼患者129例183眼分为注气组和对照组,注气组(68例97眼)行复合式小梁切除加前房注射过滤空气,对照组(61例86眼)行复合式小梁切除术,随访时间3~6(平均4.5)mo,观察术后视力变化、眼压、滤过泡形成、并发症情况,同时记录非计划再次手术情况、住院天数及住院总费用。
结果:注气组术后浅前房、恶性青光眼、非计划再次手术发生率低于对照组,注气组住院天数少于对照组,注气组住院总院费用低于对照组(均P<0.05)。两组不同时间眼压比较,差异有统计学意义(F组别=42.394,P组别<0.001; F时间=7.373,P时间<0.001; F交互=23.903,P交互<0.001)。注气组术后1、3d眼压均高于对照组(P<0.001),术后7d,3mo两组眼压均无差异(P>0.05)。术后1、3、7d,1mo两组前房闪辉情况均无差异(P>0.05),术后3mo两组视力变化、滤过泡形成均无差异(P>0.05)。
结论:复合式小梁切除加前房注射过滤空气治疗原发性慢性闭角型青光眼可降低术后浅前房、恶性青光眼及非计划再次手术的发生率,不会加重前房炎症反应,可以安全地保留患者的剩余视功能,同时还可以缩短住院天数及住院总费用,对眼压、视力、滤过泡形成无明显影响。 相似文献

Purpose: To investigate the efficacy of trabeculectomy, phacotrabeculectomy and phaco-emulsification in the management of primary angle closure glaucoma (PACG). Methods: A prospective observational study was performed in 88 chronic PACG patients (97 eyes) who were divided into three groups following defined indications to receive different surgical interventions. The indications and clinical outcomes were evaluated. The mean follow-up was (17.7±4.9) months. Results: Success rate in trabeculectomy, phacotrabeculectomy and phacoemulsification group was 81.08%, 78.57‰ and 81.25‰, respectively. The anterior chamber depth was deeper and the angle was wider postoperatively vs. preoperatively both in phaco-trabeculectomy and phacoemulsification group. No obvious changes were seen in trabeculectomy group. The coefficient of outflow facility of aqueous humor (C values) significantly increased in three groups postoperatively (P < 0.01). No severe intra-operative complications were found and the incidence of postoperative complications was low. Five eyes sustained hypotony 3±1.87 months in trabeculectomy group and 1 eye happened malignant glaucoma in phacotrabeculectomy group. The visual acuity in patients with phacotrabeculectomy plus intraocular lens implantation and those only with phacoemulsification plus intraocular lens implantation were improved 78.57% and 93.74%, respectively. No significant improvement was found in trabeculectomy group (χ2 = 47.10, P < 0.001). Conclusion: Three surgical interventions were beneficial to manage PACG and with co-existing cataract. The indication choosing was suggested according to visual acuity, angle closure circumference, cataract, medication requirements and optic nerve damage. Phacotrabeculectomy was recommended for angle closed ≥180° circumference while phacoemulsification for angle closed < 180°. 相似文献

Trabeculectomies performed on 33 eyes were compared to 28 standard filtering procedures done at the same institution during a 4 year period. The success rates in the two groups of patients whether white or black were statistically comparable, 92% in the trabeculectomy group and 77% in the standard filtering surgical group. Only cases of phakic open angle glaucoma, chronic angle closure and combined mechanism glaucoma were considered. Cases of secondary glaucoma, previous surgical failure and aphakic nonpupillary block glaucoma did uniformly poorly. When trabeculectomy was performed with "enhanced cyclodialysis" early results in a few cases were successful. The incidence of flat anterior chamber and cataracts with permanent reduction in visual acuity was significantly less in the trabeculectomy group than in the standard filtering procedure group. These results support previous studies which support trabeculectomy as successful as standard filtering procedures with the advantage of having fewer permanent serious complications. 相似文献
