简介:目的:探讨规模化白内障手术中高龄及其伴全身疾病患者安全性。方法:回顾性分析"爱心光明行"活动中高龄及其伴全身疾病患者的临床资料。结果:本组高龄伴全身疾病患者213例(90.6%),其中循环系统疾病、代谢性疾病、呼吸系统疾病分别占65.1%,13.6%和11.1%。术前因首次全身疾病评估暂缓手术25例(10.6%),经有效治疗后手术。手术脱残率95.4%,脱盲率84.2%,12例视力〈0.1患者眼底检查均有不同程度的眼底病变。结论:加强术前综合因素评估,充分治疗全身疾病,严格掌握手术适应证,术中监护,操作轻巧,手术时间10~15min,是保证规模化白内障手术中高龄或伴全身疾病患者安全性的有效措施。

简介:目的:研究视网膜血管疾病在印度喜马偕尔邦丘陵地带(海拔500~4500m)的患病模式/分布。方法:对西姆拉三级医院眼科自2008-08/2013-04期间的视网膜疾病患者进行回顾/前瞻性研究。选取5600位中的4323名患者作为研究对象。该数据均来自于医院记录,随后根据患者的年龄,性别分布情况和诊断结果进行分析。所有患者都进行了视力,屈光,裂隙灯和眼底检查。以眼底临床记录和眼底照相记录来确定诊断。应用眼底照像机(KowaFundusCameraVX-10)进行照相,必要时进行眼底荧光素血管造影。结果:在4323例患者中,男性视网膜疾病患者有2563例(59.29%),多于女性1760例(40.71%)。在525例(12.14%)糖尿病视网膜病变患者中,轻度非增殖性糖尿病视网膜病变133例(3.08%),中度156例(3.60%),重度120例(2.78%),增殖性糖尿病视网膜病变116例(2.68%)。在393例(9.10%)高血压性视网膜病变患者中,I级高血压性视网膜病变患者130例(3.01%),II级111例(2.57%),III级131例(3.03%),IV级21例(0.49%)。在660例(15.27%)其他视网膜血管疾病中,视网膜分支静脉阻塞229例(5.30%),视网膜中央静脉阻塞55例(1.27%),半视网膜中央静脉阻塞8例(0.19%),视网膜中央动脉阻塞20例(0.46%),视网膜分支动脉阻塞4例(0.09%),眼部缺血综合征1例(0.02%),早产儿视网膜病变9例(0.21%),视网膜大动脉瘤5例(0.12%),近中心凹毛细血管扩张6例(0.14%),贫血性视网膜病变16例(0.37%),白血病视网膜病变10例(0.23%),视网膜前出血52例(1.20%),Coats病8例(0.19%),睫状视网膜动脉阻塞1例(0.02%)例,Eales病10例(0.23%),血管炎17例(0.39%)以及有临床意义的黄斑水肿209例(4.83%)。结论:糖尿病视网膜病变是最常见的视网膜血管疾病。视网膜疾病已经成为印度一个主要公共卫生问题。此研究将有利于对喜�
