目的观察两种不同手术方案治疗新生血管性青光眼的疗效。方法将208例新生血管性青光眼患者随机分为研究组和对照组各104例。对照组给予患者睫状体光凝术治疗,研究组给予患者玻璃体腔内注射治疗。对比2组患者治疗后平均视力、平均眼压变化情况、并发症率及手术成功率。结果 2组患者治疗前眼压和视力差异无统计学意义(P>0.05)。治疗后3d、6个月眼压和视力水平均较治疗前有所恢复,且研究组优于对照组,差异有统计学意义(P<0.05)。研究组患者手术成功率显著高于对照组,并发症发生率明显低于对照组,差异均有统计学意义(P<0.05)。结论玻璃体腔内注射能显著改善病情,提高手术成功率并降低并发症率,是一种安全高效的治疗方式。 相似文献

Purpose: To compare the success rates and safety of transscleral cyclophotocoagulation (TSCPC) for the treatment of refractory glaucoma using the slow coagulation technique and the conventional technique.Methods: A retrospective, interventional case series of 44 patients (44 eyes) who underwent TSCPC using the slow coagulation technique (22 eyes) and conventional technique (22 eyes) in a tertiary hospital was done. The main outcome measures were success and complications. Success was defined as a final intraocular pressure (IOP) between 6 and 21 mmHg with or without IOP lowering medications with the cessation of oral carbonic anhydrase inhibitor at 12 months.Results: Preoperative characteristics were statistically similar with regard to age, sex, laterality, diagnosis, IOP, and the number of glaucoma medications used. Both procedures had similar success rates of 40.9% and 36.3% in the conventional technique group and slow coagulation group, respectively (p = .757). The slow coagulation group had less prolonged anterior chamber inflammation (p = .048).Conclusions: Diode laser TSCPC using the slow coagulation technique is a safe and effective technique for lowering IOP in patients with refractory glaucoma in Chinese eyes. 相似文献

Purpose
To evaluate the clinical efficacy and safety of controlled contact transscleral diode laser Cyclophotocoagulation (COCO) procedure in reducing the Intraocular Pressure (IOP) among patients with refractory glaucoma.Methods
Thirty two patients (35 eyes) with refractory glaucoma in prospective clinical studies were treated with trans-sclera diode laser in a controlled manner. The energy power used was 5 W in adults and 3 W in children, exposure time was 0.5 s, a total of 16 shots were applied over ciliary body and four shots in each quadrant. Pre and postoperative IOP were measured at different postoperative visits. Snellen visual acuity, the number of anti-glaucoma medications and associated complications were also recorded. Student T test was used to compare the pre and post intervention IOPs, while Wilcoxon Signed Ranks test was used, to detect significance change in medication dependency.Results
The mean (SD) follow up time was 80.2(±9.6) months, range (36–84) m, where the mean IOP was significantly reduced from 35.1 mm Hg (±10.7) before intervention to 18.8 mm Hg (±7.3) after intervention, in the final visit (P < 0.0001). Complete success was achieved in seven eyes (20%), 22 eyes (62.8%) showed qualified successes and complete failure was reported in six eyes (17.1%). The overall success rate was 82.8% (95% CI: 70.4–95.3). Visual acuity improved in three eyes (8.5%), no change took place in 27 eyes (77.1%) and decreased in five eyes (14.2%). The number of anti-glaucoma medications has significantly changed between pre and post intervention (P < 0.0001). No cases of hypotony, phthisis bulbi or sympathetic ophthalmia were reported.Conclusion
Controlled COCO is a simple procedure, safe with minimal complications and fewer side effects. 相似文献9.

Background
Endoscopic cyclophotocoagulation (ECP) is a relatively new method of cyclodestruction which can be used in the management of refractory glaucomas.Aim
To evaluate the safety and efficacy of ECP in the management of refractory glaucomas.Settings and Design
Prospective interventional non-comparative study.Materials and Methods
Fifty eyes of 50 patients with refractory glaucoma, whose intraocular pressures (IOP) were not under control with maximal medical therapy underwent ECP, by the anterior, or pars plana route. IOP, best corrected visual acuity (BCVA), and the number of anti-glaucoma medications, were compared postoperatively to preoperative values. Success was defined as IOP ≤ 22 mmhg, with or without use of medications.Statistical analysis used
Student''s t test and repeated measures ANOVA were used to evaluate change in IOP and Student''s t test, for comparison of BCVA. Kaplan Meier survival curve was plotted. Wilcoxon signed rank test was used to evaluate reduction in medications.Results
Patients were followed for an average of 12.27 months (3-21months). IOP decreased significantly from 32.58 ± 9.16 mmHg to 13.96 ± 7.71 mmHg at last follow-up (P<0.001, student''s t test). BCVA was significantly improved in the postoperative period (P<0.001, student''s t test). The average number of antiglaucoma medications decreased from 2.51 ± 0.97 to 1.09 ± 1.16 (P<0.001, Wilcoxon signed rank test). ECP had a success rate of 82.2%.Conclusion
Endoscopic cyclophotocoagulation is an effective procedure in this subset of refractory glaucomas. 相似文献10.
