  • 微小核糖核酸与眼底疾病的相关性研究进展

    微小核糖核酸(miRNA)是近年来发现的真核细胞内一类稳定、非编码可调控的核糖核酸(RNA)分子,主要通过与靶基因信使RNA(mRNA)3prime;端非编码区碱基配对的方式,引起靶标mRNA降解或翻译抑制,从而参与真核生物的生长发育、细胞增生凋亡及肿瘤发生等多种生理和病理过程。miRNA表达变化与眼底新生血管性疾病、糖尿病视网膜病变、视网膜色素变性、视网膜母细胞瘤、脉络膜黑色素瘤等眼底疾病的发生发展存在一定的相关性。进一步探索miRNA与眼底疾病发生发展的相互关系,可能有助于从基因水平上认识、预防和治疗这些眼底疾病。

  • Fundus Analysis of Familial Exudative Vitreoretinopathy

    ObjectiveTo observe and explore the fundus characteristics and fundus fluorescein angiography of familial exudative vitreoretinopathy (FEVR) in different stages. MethodsA total of 15 patients (23 eyes) diagnosed as FEVR in the West China Hospital of Sichuan University from January 2007 to November 2013 were included. Clinical data and reports of fundus exams and fundus fluorescein angiography (FFA) were retrospectively analyzed. ResultsOne eye (4.35%) was classified as stage Ⅰ, 10 eyes (43.48%) were classified as stage Ⅱ, 8 eyes (34.78%) were classified as stage Ⅲ, and 1 eye (4.35%) and 3 eyes (13.04%) were classified as stage Ⅳ and V, respectively. The outcomes of fundus exams showed that the number of peripheral retinal blood vessels increased, and vessels straightened as well as narrowed, especially in the temporal area. FFA showed blood vessels suddenly shut in the equatorial retina and peripheral non-perfusion areas were observed. ConclusionTypical fundus characteristics and fundus fluorescein angiography changes of FEVR can be observed in different stages. Comprehensive fundus exams and family history are helpful to confirm relevant diagnosis.
