不同术式治疗新生血管性青光眼的疗效比较

目的：比较不同手术方法治疗新生血管性青光眼（neovascular glaucoma,NVG）的疗效。方法：对接受不同术式治疗的57例57只眼NVG的临床资料进行回顾性分析,其中行单纯睫状体冷凝术20例（A组）,改良小梁切除术15例（B组）,引流阀植入术联合全视网膜光凝术22例（c组）。比较各组患者手术前后主观眼痛症状、眼压及视力变化情况,并随访3～6个月。结果：A组患者出院时的平均眼压为（28．13＋4．83）mmHg,B组为（19．24±5．48）mmHg,C组为（21．22±4．76）mmHg。随访期间,术后A组9例眼压正常,手术成功率45％;B组11例眼压正常,手术成功率73．3％;C组13例眼压正常,手术成功率57．1％。B组手术成功率最高,A组最低。结论：三种手术方法均可不同程度降低新生血管性青光眼的眼压。单纯睫状体冷凝术后眼压控制效果欠佳,有视力眼不宜采用此种手术方式;改良小梁切除术是治疗新生血管性青光眼安全、有效、经济的手术方式;引流阀植入术联合全视网膜光凝术费用较高。

Intracameral bevacizumab and mitomycin C Trabeculectomy for eyes with neovascular glaucoma: a case series

The purpose of this study was to describe the surgical outcomes and safety of intracameral bevacizumab during trabeculectomy in eyes with neovascular glaucoma. Pilot study included four eyes (four patients) with refractory neovascular glaucoma submitted to fornix-based trabeculectomy with adjunctive use of bevacizumab in the anterior chamber during the procedure. Patients were previously treated with panretinal photocoagulation as standard therapy. Variables evaluated were intraocular pressure, bleb appearance, iris neovascularization, intraoperative/postoperative complications, and visual outcomes. No intraoperative complication was observed. The mean follow-up period was 12.75 (range, 12–15 months). All eyes showed significant intraocular pressure control postoperatively. Iris neovascularization reduced significantly within 1 month after surgery. Mild anterior chamber inflammation was observed during follow-up in all eyes. No significant postoperative complication was observed, and no patient presented visual acuity deterioration. Intracameral bevacizumab may be used as an adjunctive therapy during trabeculectomy in eyes with neovascular glaucoma.     

Long-Term Outcomes and Prognostic Factors of Trabeculectomy following Intraocular Bevacizumab Injection for Neovascular Glaucoma

Purpose

To evaluate long-term outcomes and identify prognostic factors of trabeculectomy following intraocular bevacizumab injection for neovascular glaucoma.

Methods

Sixty-one eyes of 54 patients with neovascular glaucoma treated by trabeculectomy following intraocular bevacizumab injection were consecutively enrolled. Surgical success criteria were sufficient intraocular pressure (IOP) reduction (IOP ≤21 mmHg, ≥20% IOP reduction, no additional medications or glaucoma surgeries) without devastating complications (loss of light perception, phthisis bulbi, and endophthalmitis) or significant hypotony (IOP ≤5 mmHg continued ≥6 months and until the last follow-up visit or hypotony requiring intervention). Kaplan-Meier survival curves and Cox regression analysis were used to examine success rates and risk factors for surgical outcomes.

Results

The follow-up period after trabeculectomy was 45.0 ± 22.2 months (mean ± standard deviation). Surgical success rate was 86.9 ± 4.3% (± standard error), 74.0 ± 6.1%, and 51.3 ± 8.6% at 1, 3, and 5 years. Multivariate Cox regression analysis identified two risk factors; lower preoperative IOP (≤30 mmHg) for surgical failure and hypotony [hazard ratio (HR), 2.92, 6.64; 95% confidence interval (CI), 1.22 to 7.03, 1.47 to 30.0; P = 0.018, 0.014, respectively], and vitrectomy after trabeculectomy for surgical failure with or without hypotony criteria (HR, 2.32, 4.06; 95% CI, 1.02 to 5.28, 1.30 to 12.7; P = 0.045, 0.016, respectively).

Conclusions

The long-term outcomes of trabeculectomy following intraocular bevacizumab injection for neovascular glaucoma were favorable. Lower baseline IOP was associated with development of significant hypotony, while additional vitrectomy was related to insufficient IOP reduction.

摘要 目的：总结26例中国先天性晶状体异位患者的基因诊断及晶状体异位的手术疗效。方法：回顾性收集2019年3月-2020年3月就诊于北京同仁医院眼科来自不同家系的双眼先天性晶状体异位患者26例共52眼。收集详细临床资料，提取外周静脉血全基因组DNA，应用靶向基因捕获技术筛查晶状体异常相关基因突变对所有患者进行基因诊断，采取微创晶状体-玻璃体切除或白内障超声乳化手术，记录视力、人工晶状体位置及主要并发症，采用配对t检验对术前术后最佳矫正视力进行比较。结果：患者均为汉族，男性14例，女性12例，年龄（21.2±15.2）岁。25例患者存在FBN1突变，1例为GJA8突变。22例（84.6%）可确诊为马凡综合征，3例诊为"潜在马凡综合征"。42眼采取微创晶状体-玻璃体切除类手术，7眼采取白内障超声乳化类手术。有31眼（59.6%）存在视网膜变性行网膜激光光凝。平均随诊时间（15.7±3.7）月，术后6个月及末次随访的最佳矫正视力（最小分辨角对数视力，0.30±0.16及0.21±0.11）均高于术前（0.76±0.31），差异有统计学意义（t=12.492，P＜0.001；t=13.171，P＜0.001）。术后所有眼的人工晶状体位置及稳定性良好，未发生视网膜脱离、黄斑水肿、人工晶状体脱位、人工晶状体偏位、继发性青光眼、眼内炎等并发症。结论：马凡综合征是此26例中国人先天性晶状体异位的主要病因，FBN1基因突变检测可为确诊提供有力证据，微创晶状体-玻璃体切除联合人工晶状体悬吊术效果好。     

The Influence of Phacoemulsification on Surgical Outcomes of Trabeculectomy with Mitomycin-C for Uveitic Glaucoma

Purpose

To evaluate the influence of phacoemulsification after trabeculectomy on the postoperative intraocular pressure (IOP) in eyes with uveitic glaucoma (UG).

Setting

Kumamoto University Hospital, Kumamoto, Japan.

Design

A retrospective cohort study.

Methods

The medical records of patients with UG who had trabeculectomy with mitomycin-C (MMC) were reviewed. Complete and qualified surgical failures were defined by an IOP of ≥21 mmHg (condition A), ≥18 mmHg (condition B), or ≥15 mmHg (condition C) without and with glaucoma eye drops, respectively. Kaplan-Meier survival analysis, generalized by the Wilcoxon test, and the Cox proportional hazards model analysis were conducted. Post-trabeculectomy phacoemulsification was treated as a time-dependent variable. In 24 (30%) of the included 80 eyes, phacoemulsification was included, and they were divided into two groups: groups I (8 eyes with phacoemulsification within 1 year after trabeculectomy) and group II (16 eyes after 1 year following trabeculectomy).

Results

Multivariable Cox proportional hazards model analysis showed post-trabeculectomy phacoemulsification was a significant factor in both complete success and qualified success based upon condition C (P = 0.0432 and P = 0.0488, respectively), but not for the other conditions. Kaplan–Meier survival analyses indicated significant differences in success probabilities between groups I and group II for complete success and qualified success based upon condition C (P = 0.020 and P = 0.013, respectively). There was also a significant difference for qualified success based upon condition B (P = 0.034), while there was no significant difference for the other conditions.

Conclusion

Post-trabeculectomy phacoemulsification, especially within 1 year, can cause poor prognosis of IOP control of UG eyes after trabeculectomy with MMC.     

Application of 5-Fluorouracil-Polycaprolactone Sustained-Release Film in Ahmed Glaucoma Valve Implantation Inhibits Postoperative Bleb Scarring in Rabbit Eyes

This study was designed to investigate whether 5-fluorouracil (5-Fu)-polycaprolactone sustained-release film in Ahmed glaucoma valve implantation inhibits postoperative bleb scarring in rabbit eyes. Eighteen New Zealand white rabbits were randomly divided into three groups (A, B and C; n = 6 per group). Group A received combined 5-Fu-polycaprolactone sustained-release film application and Ahmed glaucoma valve implantation, group B received local infiltration of 5-Fu and Ahmed glaucoma valve implantation, and group C received Ahmed glaucoma valve implantation. Postoperative observations were made of the anterior segment, intraocular pressure, central anterior chamber depth, blebs, drainage tube, and accompanying ciliary body detachment. The pathology of the blebs and surrounding tissues were observed at month 3 postoperatively. We revealed that the 5-Fu-polycaprolactone sustained-release film maintained a release concentration range of 13.7 ± 0.12 to 37.41 ± 0.47 μg/ml over three months in vitro. Postoperatively, diffuse blebs with ridges were found in all eyes in group A, two blebs were observed in group B, and no bleb formation was present in group C. The postoperative central anterior chamber depth in group A was significantly less than that of the other two groups. The postoperative intraocular pressure of group A stabilized at 6.33–8.67 mmHg, whereas that of group C gradually remained at 7.55–10.02 mmHg. The histopathology showed that the fibrous tissue thickness of the blebs in group A was significantly thinner than that of the other groups. We conclude that the 5-Fu-polycaprolactone sustained-release film had a sustained drug release effect, which promoted the inhibition of bleb scarring after Ahmed glaucoma valve implantation.
