A Case of Refractory Childhood Glaucoma Secondary to Weill-Marchesani Syndrome: Management with Combined CO2 Laser-Assisted Sclerectomy Surgery and Trabeculectomy

A 2-year-old girl was diagnosed as Weill-Marchesani syndrome with typical systemic features of short stature, short and stubby hands and feet, language disorders and mental retardation. He developed bilateral angle closure glaucoma, ectopia lentis and suffered visual loss from the ocular features of Weill-Marchesani syndrome. The child was successfully treated by combined CO₂ laser-assisted sclerectomy surgery and trabeculectomy.     

飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障

目的：评估飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障的有效性和安全性。

方法：回顾性病例对照研究。2019-10/2021-10入院合并难治性青光眼的白内障患者53例53眼，依据自愿选择分为飞秒激光辅助白内障超声乳化(FLACS)组26例26眼和常规白内障超声乳化(CPCS)组27例27眼。两组分别行FLACS和CPCS联合Ahmed青光眼引流阀植入术。比较两组患者术中超声乳化能量释放量(CDE)、有效超声时间(EPT)的差异和术前与术后抗青光眼药物数量的变化，以及术后观察不同时期(1d，1wk，1、3mo)在提高最佳矫正视力(BCVA)，降低眼压、角膜内皮细胞损伤程度和手术并发症及成功率状况。

结果：FLACS组术中CDE和EPT明显低于CPCS组(t=8.50、5.16； P<0.01、=0.001)。两组术后抗青光眼药物较术前均明显减少(t=9.12、7.76； P=0.011、0.016)，但两组间无差异(t=1.79，P=0.082)。两组术后BCVA均较术前改善，眼压均较术前降低(P<0.05)。FLACS组在术后早期(1d，1wk)BCVA的改善较CPCS组更显著(t=9.74、8.49； P=0.008、0.012)，但在术后1、3mo的BCVA改善程度并无不同(t=0.62、0.44； P=1.415、2.021)。CPCS组在术后随访不同时期的角膜内皮细胞损伤较FLACS组更明显(P<0.05)。术后随访的不同时期FLACS组和CPCS组在控制眼压方面无差异(F_组间=0.64，P_组间=0.421)。FLACS组的手术并发症发生率27%(7/26)较CPCS组89%(24/27)低(χ²=20.95，P<0.01)，其中角膜水肿(8% vs 41%)、前囊撕裂(0 vs 11%)在FLACS组中明显低于CPCS组，后囊破裂(0 vs 7%)、玻璃体脱出(0 vs 4%)及人工晶状体偏位(0 vs 7%)也均发生在CPCS组。但两组的治疗总成功率相近(P=28.718)。

结论：飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术可充分发挥联合手术的精准微创可控优势，帮助合并难治性青光眼的白内障患者有效降低眼压及更早获得视力恢复。

Preservative-free versus preserved brimonidine %0.15 preparations in the treatment of glaucoma and ocular hypertension: short term evaluation of efficacy,safety, and potential advantages

Abstract

Purpose: To compare the efficacy, safety, and potential advantages of the preservative-free versus preserved brimonidine %0.15 preparations in patients with primer open-angle glaucoma (POAG) or ocular hypertension (OHT).

Methods: Forty-two eyes of the 21 treatment-naive patients with POAG or OHT were enrolled in this study. Eyes were randomly assigned to receive brimonidine-purite 0.15% or preservative-free brimonidine 0.15% two times daily. Efficacy of the two eye drops was assessed by measuring the intraocular pressure (IOP) at 9–10 am at baseline and week 4. Safety and potential advantages of the drops were evaluated at weeks 4 in terms of ocular symptoms and tear parameters. Ocular symptom values of the patients were evaluated with a scale of 0–4 (0?=?no discomfort and 4?=?severe discomfort).

Results: Both of the brimonidine tartrate formulations resulted in statistically similar IOP reduction (preserved formulation; ?5.2?mmHg [22.9% reduction] preservative-free formulation; ?5.7?mmHg [24.1% reduction], p?=?0.37). It was found that brimonidine tartrate formulations with and without topical preservatives did not produce a statistically significant difference in pain, stinging, and blurred vision at the upon instillation (p?>?0.05). However, the burning sensation was significantly higher in the preservative-free formulation at the first instillation compared to the preserved formulation (p?=?0.01). Also, there was no statistically significant difference between the two formulations in terms of symptoms (itching, burning, tearing, stinging, and photophobia) and tear parameters during the day (p?>?0.05).

Conclusions: Although topical preservative-free brimonidine tartrate treated eyes had a more burning sensation at the first drop, the two formulations were similar in terms of ocular tolerability in the short term period. Also, both formulations were found to reduce IOP at a similar rate.     

内路小梁切开联合白内障超声乳化吸除术治疗原发性开角型青光眼的短期疗效

目的 对比内路小梁切开联合白内障超声乳化吸除术和单纯内路小梁切开术治疗合并白内障的原发性开角型青光眼（primary open angle glaucoma，POAG）的早期手术效果和并发症。设计 病例对照研究。研究对象2018年3月至2019年3月在北京同仁眼科中心住院手术治疗的合并白内障的POAG患者36例（36眼）。方法 根据患者选择的手术方式，将患者分为两组：行内路小梁切开联合白内障超声乳化吸除术的POAG患者12例（12眼）为观察组，行内路小梁切开术的POAG患者24例（24眼）为对照组。记录并比较两组患眼术前、术后1、2、3、5天、1周、1个月时眼压、视力、并发症和使用降眼压药的种类。主要指标 眼压、视力、并发症和降眼压药物种类。结果 观察组和对照组术前最高眼压分别为（34.08±8.21）mmHg和（37.75±8.61）mmHg（P=0.46）,观察组术后第1天、1周、1个月的平均眼压分别为（20.75±11.89）mmHg、（21.23±8.72）mmHg、（15.00±2.22） mmHg，对照组术前、术后第1天、1周、1个月的平均眼压分别为（16.08±5.63）mm Hg、（22.08±11.48）mmHg、（16.05±5.25）mmHg，两组术后眼压整体变化趋势随时间降低（P<0.001）,两组间术后眼压波动虽然存在差异，但是无统计学意义（P=0.77）。观察组和对照组术后1个月降眼压幅度分别为53.09%±15.19%和55.68%±15.63%（P=0.64）。观察组和对照组术前降眼压药物使用种类分别为（2.67±0.99） 种和（3.08±0.72）种（P=0.16），术后1个月时分别下降至（0.17±0.58）种和（0.96±1.33）种（P=0.06）。观察组和对照组组术后眼压反跳发生率分别为16.67%和54.17%（P=0.03）。前房积血为术后最常见的并发症, 观察组发生率为83.3%，对照组为62.5%（P=0.21)。观察组和对照组睫状体脱离发生率分别为25.0%和75.0%（P=0.004）。观察组中，8眼（66.7%）术后生活视力提高，4眼（33.3%）视力恢复至术前水平，0眼视力降低；对照组中，20眼（83.3%）术后生活视力恢复至术前水平，4眼（16.7%）视力降低（P<0.001）。结论 对于合并白内障的开角型青光眼患者，内路小梁切开联合白内障超声乳化吸除术和单纯内路小梁切开术在术后1个月时降眼压作用相似。联合手术术后视力改善明显，眼压反跳发生率较单纯内路小梁切开术低，是一种安全有效的手术方式，远期效果有待进一步观察。
