简介:目的:使用Pentacam三维眼前段分析仪比较高度近视眼与正常人(正视眼)中央前房深度(centralanteriorchamberdepth,CACD)和前房角(anteriorchamberangle,ACA)两项前房参数差异,进一步了解高度近视眼的解剖学特点。方法:收集2010-10/2011-06在我院门诊就诊的正视眼82例,收集同期我院门诊与准分子激光中心就诊的高度近视眼68例,采用Pentacam三维眼前段分析仪测量CACD和ACA。对高度近视组与正视眼组的前房参数值进行两样本t检验,比较两组间参数有无差异。结果:Pentacam三维眼前段分析仪测得正常人CACD平均值为3.02±0.47mm,ACA平均值为33.26°±6.20°。高度近视眼的CACD平均值为3.24±0.38mm,ACA的平均值为39.55°±6.68°。高度近视眼与正视眼的两项前房参数值均存在显著性差异(均P〈0.05)。结论:Pentacam三维眼前段分析仪测量前房参数,高度近视眼与正视眼相比中央前房深度深、前房角宽。
简介:目的探讨玻璃体的手术对复杂无晶状体眼视网膜脱离(AphakicRetinalDetachment,ARD)和人工晶状体眼视网膜脱离(PseudophakicRetinalDetachment,PPRD)(PVRC级以上)的治疗效果.方法回顾性分析78例87眼ARD和PPRD,所有病人均行玻璃体切割联合眼内填充物治疗.结果首次手术视网膜复位率为78.16%,最终视网膜复位率90.8%.视力下降11眼(12.7%),不变15眼(17.2%),提高59眼(70.1%).结论彻底的玻璃体切除加视网膜切开、视网膜前膜剥除,适当应用环扎玻璃体填充物可使复杂PPRD,ARD达到较高的视网膜复位率.但ARD、PPRD一旦发生则病情进展迅速,治疗棘手,视力预后差,应从白内障手术开始加强预防.
