简介:目的观察壳聚糖对兔青光眼滤过手术模型中VEGF表达的影响,探讨壳聚糖在青光眼滤过手术中抗瘢痕形成的应用价值。方法将健康成年大白兔随机分为实验组(A组),以2.5%壳聚糖液注射手术部位,手术对照组(B组)和正常对照组(C组),术后1w、2w、4w、12w免疫组织化学染色,比较三组VEGF(Vascularendothelialgrowthfactor,VEGF)阳性表达率,观察眼压情况。结果术后免疫组织化学染色结果显示B组VEGF阳性表达率较高,A、C组较低。三组眼压有显著性差异(P〈0.01)。结论壳聚糖在兔青光眼滤过手术模型中的应用可以下调VEGF的表达,更持久地降低眼压。
简介:目的:探讨HSP60(热休克蛋白60)在大鼠急性青光眼模型视网膜组织中的表达及其与血清中相应抗体的关系。方法:将SD大鼠70只随机分为高眼压组60只,正常对照组10只。大鼠全身及表面麻醉后,将一盛有等渗的生理盐水的储容器相连的7号针头于3:00位的角膜缘处刺入前房,提升储容器的高度,使眼内压达到110mmHg,但不超过150mmHg,观察大鼠眼前段变白,且视网膜色白,未见红色反光时即为视网膜缺血,缺血1h后再灌注,并于再灌注后2,6,12,24,72,168h将大鼠麻醉过量致死,处死前测眼压,抽血2mL,供酶联免疫吸附测定使用,分析视网膜组织内HSP60抗原产生的血清中相应抗体水平。并立即取出眼球,同时对鼠眼视网膜组织进行石蜡切片,采用免疫组化法检测视网膜组织中HSP60的表达及分布情况,并对检测结果进行统计学分析。结果:急性高眼压诱导的视网膜缺血/再灌注组眼压明显升高,视网膜组织中的HSP60阳性表达率在术后各时间点,高眼压组与正常对照组比较,差异有统计学意义(F=97.21,40.72,83.85,95.82,48.63及44.37,均P〈0.01)。神经节细胞(retinalganglioncell,RGC)中HSP60阳性表达随着眼压升高及高眼压持续时间延长逐渐增强,且视网膜神经纤维层中也出现较明显的HSP60阳性表达。结论:HSP60表达增强可能在急性高眼压所致的视神经病变中具有重要作用。

简介:目的对眼科住院医师实施白内障囊外摘除术及人工晶体植入术中,手术并发症的预防及处理能力培训探讨。方法开展防盲治盲工作中,住院医师共施行215例(235只眼)的白内障囊外摘除术及人工晶体植入手术,对发生并发症进行回顾性分析。结果术后发生的手术并发症:后囊破裂15只眼(6.4%),虹膜脱出5只眼(2.1%),虹膜根部离断3只眼(1.3%),角膜水肿45只眼(19.1%),瞳孔上移10只眼(4.3%),前房皮质残留2只眼(0.9%),后囊瞳孔区皮质残留2只眼(0.9%),继发性瞳孔阻滞性青光眼1只眼(0.4%),黄斑囊样水肿1只眼(0.4%)。结论后囊膜破裂和角膜水肿是本组白内障囊外摘除术及人工晶体植入手术主要并发症,住院医师手术者应规范掌握手术要点是预防并发症发生的关键,对出现的手术并发症应积极妥善处理是减少并发症有效措施。
简介:目的观察生物羊膜与丝裂霉素C(MMC),应用于青光眼小梁切除术中治疗青光眼的临床疗效。方法随机选择39例(48只眼),分为羊膜组(22只眼)和丝裂霉素组(26只眼)。羊膜组施行小梁切除术联合巩膜瓣下生物羊膜植入术,丝裂霉素组施行小梁切除术联合巩膜瓣下放置丝裂霉素C,浓度为0.25mg/ml,时间2分钟,术后随访3-9月,比较两种手术方式的临床疗效。结果术后与术前相比:两组眼压均明显降低。术后并发症:羊膜组副反应小,引起的并发症主要有术后浅前房;丝裂霉素组引起的并发症主要有滤过泡渗漏、低眼压等。结论小梁切除联合生物羊膜植入术可有效地减少瘢痕组织形成,且并发症较丝裂霉素少,是治疗青光眼安全、有效的手术方法。
