简介：每年,在低收入和中等收入国家有数千名婴儿和儿童失去他们的视力和生命,因为一种叫视网膜母细胞瘤的可治愈的眼癌,通常是因为它没有被及时诊断和治疗。尽管视网膜母细胞瘤相对罕见,但对受其影响的儿童可能会造成破坏性的后果。如果治疗太晚,可能会导致失去眼睛,侵袭大脑并且导致死亡。

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�

简介：随着建立在医学科学研究基础上认识的不断深入,血管内皮生长因子（vascularendothelialgrowthfactor,VEGF）被确认是脉络膜新生血管（choroidalneovascularization,CNV）发展过程中介导血管生成和血管通透性的主要原因[1-2]。目前所知的VEGF家族包括5个成员：VEGF-A、VEGF-B、VEGF-C、VEGF-D和胎盘生长因子，其中以VEGF-A最为活跃，并与血管生成、新生血管化和血管通透性增强密切相关。
