All the patients underwent modified viscocanalostomy with injection of viscoelastic material in the surgically created ostia of Schlemm's canal(SC). The modifications included peeling of the inner wall of SC and the juxtacanalicular meshwork, use of mitomycin C, and loosely suturing the superficial scleral flap. Intraocular pressure(IOP), visual acuity, number of medications, laser goniopuncture data and complications were recorded. The definition of complete(qualified) success was an IOP equal to or lower than 21, 18, 16 mm Hg without(with or without) anti-glaucoma medications. RESULTS: The mean IOP was 33.5±9.9 mm Hg before surgery, 15.2±3.6 mm Hg(mean IOP reduction of 51%) at 5 y after surgery, and 15.6±2.8 mm Hg(mean IOP reduction of 49.9%) at 10 y after surgery(P<0.001). The number of anti-glaucoma medications dropped from 2.39±0.5 preoperatively to 0.47±0.8 at 5 y and 0.67±0.8 at 10 y postoperatively(P<0.001). The follow-up period was 104.5±37.0 mo. The qualified success rate for an IOP of 21, 18 or 16 mm Hg or less was 84% [95% confidence interval(CI): 0.80-0.88], 73%(95%CI: 0.68-0.78), and 59%(95%CI: 0.52-0.66) after 5 y, and 80%(95%CI: 0.76-0.84), 69%(95%CI: 0.64-0.74), 51%(95%CI: 0.44-0.58) after 10 y, respectively. There was a relationship between age, preoperative IOP and success rate(P<0.01, P<0.05). A total of 31 eyes(31.3%)in 31 patients underwent laser goniopuncture, decreasing the IOP from 22.9±4.3 mm Hg to 16.3±2.5 mm Hg(P<0.01). Neither blebitis nor endophthalmitis occurred.CONCLUSION: Modified viscocanalostomy could be performed to lower IOP, decrease multiple anti-glaucoma drops use as well. It's a safe procedure with less complications over 10 y in Chinese individuals with OAG.展开更多
目的调查急性发作的原发性闭角型青光眼(PACG)中慢性闭角型青光眼(CPACG)急性发作(简称"慢闭急发")和急性闭角型青光眼(APACG)发作眼(简称"急闭发作")的比率,了解两者之间是否存在解剖结构和治疗效果的差异。设计...目的调查急性发作的原发性闭角型青光眼(PACG)中慢性闭角型青光眼(CPACG)急性发作(简称"慢闭急发")和急性闭角型青光眼(APACG)发作眼(简称"急闭发作")的比率,了解两者之间是否存在解剖结构和治疗效果的差异。设计病例对照研究。研究对象确诊急性发作期的PACG患者159例(159眼)。方法入选患者在急性发作期接受初步检查后立即给予降眼压药物或激光虹膜周边成形术治疗。角膜恢复透明后行眼压、眼底、垂直杯盘比(VCDR)、视野、A超、UBM、房角镜、角膜内皮细胞计数等检查。VCDR≥0.6者为慢闭急发,VCDR<0.6者为急闭发作。眼压控制后所有病例均接受激光周边虹膜切开术(LPI)治疗。随访1年。治疗后眼压≤21 mm Hg者为眼压控制,随访观察;>21 mm Hg为眼压失控,先联合降眼压药物治疗,无效则行小梁切除术治疗。主要指标VCDR、眼压、发作持续时间(AD)、虹膜前粘连(PAS)范围、前房深度(ACD)、晶状体厚度(LT)、眼轴(AL)、眼压控制率等。结果所有病例(AD≤720 h)中VCDR≥0.6者占15%。AD≤168 h病例中VCDR≥0.6者占11.2%。随着AD延长VCDR≥0.6比率上升。AD≤168 h的病例中,对慢闭急发与急闭发作比较:AD分别为15(10,52)h、23(12,72)h(P=0.508);慢闭急发的PAS范围8.0(3.0,11.5)钟点,显著高于急闭发作2.0(0.0,6.0)钟点(P=0.004);ACD和LT无显著性差异,但是慢闭急发的AL(22.31±0.72 mm)大于急闭发作者(21.73±0.98 mm)(P=0.004)。急性发作期治疗中两组眼压相近。LPI术后完成1年随访的病例为73.6%(92/125)。LPI眼压控制率:慢闭急发55.6%(5/9)低于急闭发作的79.5%(66/83)(P=0.104)。结论急性发作PACG中慢性闭角型青光眼仅占十分之一。慢闭急发者比急闭发作者具有更大范围的PAS、更长的眼轴。慢闭急发LPI的治疗效果劣于急闭发作。展开更多
