玻璃体切除在眼球壁异物摘出术中的应用

目的探讨玻璃体切除术在眼球壁异物摘出术中的价值。方法对33例患者,采用玻璃体切除术,联合视网膜切开、眼内光凝、网膜复位等手段摘取眼球壁异物。结果33例异物取出率达100%,21例术后视力有不同程度的提高,视力平均提高(4.0±2.9)行;9例不变;63例视力下降。术后并发视网膜脱离2例,白内障2例。结论玻璃体切除术能有效地治疗眼球壁异物;选择性地联合视网膜切开可提高异物取出的成功率;眼内光凝对于预防视网膜脱离有重要意义。     

糖尿病性黄斑囊样水肿患者视野的临床研究

目的探讨临床诊断以黄斑囊样水肿(cystoid macular edema,CME)为主要表现的糖尿病性视网膜病变患者的视野改变特征,为糖尿病性CME的诊断和预后判断提供依据。方法A组(无CME):32例(32只眼);B组(有CME):26例(26只眼)。采用重庆康华科技有限公司的(APS-6000B型)全自动电脑视野检查仪,测定参数:平均视敏度、视敏度标准差、平均缺损。同时测定糖化血红蛋白、血压和空腹血糖。结果A组患者平均视敏度、视敏度标准差、平均缺损三方面均高于B组,且统计学有显著性差异。糖尿病性CME患者的平均视敏度与空腹血糖无相关性,与糖化血红蛋白呈负相关,与血压呈负相关,与病程呈负相关。结论视野检查可作为糖尿病性CME的临床诊断方法之一。糖尿病性CME患者的视敏度变化受病程、糖化血红蛋白、血压的影响,而空腹血糖的影响不大。     

迟发性后房型人工晶体脱位4例分析

白内障超声乳化囊外摘除联合后房型人工晶体植入是目前首选的白内障手术方式,后房型人工晶体脱位是术后少见但严重的并发症之一。     

玻璃体内注射曲安奈德联合玻璃体切割术治疗玻璃体积血

目的探讨玻璃体内注射曲安奈德(TA)联合玻璃体切割术治疗玻璃体积血的临床应用。方法对因玻璃体积血住院手术的患者192例进行回顾性分析,比较玻璃体内注射TA联合玻璃体切割术和单纯行玻璃体切割术治疗前和治疗后ld、10d、1个月、3个月时患者的最佳矫正视力、眼压、眼内炎症反应和眼底改变。结果TA注射组在1个月、3个月最佳矫正视力高于单纯手术组,术后眼内炎症反应较单纯手术组降低,差异有统计学意义。结论与单纯玻璃体切割术比较,玻璃体内注射TA联合玻璃体切割术治疗玻璃体积血能在短期内获得更高的最佳矫正视力,并减少眼内炎症反应。     

不同巩膜瓣缝线方法在青光眼小梁切除术中的应用

目的探讨可拆除缝线小梁切除术联合丝裂霉素C在闭角型青光眼小梁切除术中的临床疗效和并发症。方法采用随机对照临床研究方法，将原发性闭角型青光眼55例随机分为2组。A组：小梁切除术＋丝裂霉素C（MMC），29例（29眼）；B组：可拆除缝线小梁切除术＋MMC，26例（29眼）。观察并比较两组术后前房、眼压、早期并发症及滤过泡情况。结果术后3月、6月、1年2组间眼压差异及手术成功率差异均无统计学意义。术后浅前房的发生率两组间差异有统计学意义。B组浅前房发生率低于A组。结论小梁切除术＋MMC与可拆除缝线小梁切除术＋MMC两种术式相比疗效相当。可拆除缝线技术的应用有利于减少术后早期并发症。     

渐进衍射多焦点人工晶状体临床应用研究

Objective To evaluate the AcrySof ReSTOR mulfifocal intraocular lens (Alcon Laborato-ries ) and compare it with Acrysof Natural (the monofocal IOL, Alcon Laboratories). Methods Thirty-one pa-tients with age-related cataract (38 eyes) were divided into two groups: MIOL, 12 patients (15 eyes) and MoIOL, 19 patients (23 eyes). Distant and near visual acuities, depth of focus, high order wave front aberra-tions and contrast sensitivity were observed at 1 week, 1 month and 3 months postoperatively. Results At 3 months postoperative,in MIOL group,the mean UCDVA,BCDVA,UCNVA,BCNVA and BDNVA were 0.87±0.11,0.91±0.10,0.70±0.14,0.71±0.24,0.72±0.11 respectively. While in MoIOL group,they were 0.85±0.11,0.88±0.12,0.31±0.07,0.63±0.16,0.244±0.08,respoctively. The UCNVA were significantly better than that of MolOL. Conelusion Acrysof ReSTOR IOL can provide excellent outcomes both in distant and near visions and it may reduce the dependence on spectacles in near vision and improve the quality-of-life.     

导升明治疗单纯型糖尿病视网膜病变的临床研究

作者用导升明(doxium,calcium dobesilute)治疗单纯型糖尿病视网膜病变患者32例，设对照组26例患者不用导升明，经治疗3月，观察治疗前后的血液流变学和眼底变化。结果表明，治疗组患者的全血粘度、血浆粘度、红细胞电泳时间和纤维蛋白原均比服药前降低(P<0.05)，而对照组无明显变化(P>0.05)。治疗组眼底病变趋于稳定和改善者多于对照组(P<0.05)，提示导升明能降低糖尿病患者的血液粘度，改善和稳定其眼底病变。 （中华眼底病杂志，1995，11：224-226）
