变性、炎症、外伤和其它各种原因导致眼底后极部的视网膜下新生血管侵入,均可发生视网膜下出血,本文仅就几种常见的疾病进行介绍。由于视网膜下新生血管性疾患的性质不同,临床所见也稍有差异,但其共同特征是:黄斑部形成盘状隆起病灶。通过眼底荧光血管造影,可查清新生血管的位置、大小和通透性,这对确定治疗方案是必不可少的。这类疾患可试行病因治疗,但无肯定的结果。对手新生血管,各种激光光凝是唯一积极的疗法。所以,早期发现新生血管,早期进行激光治疗,有时对视力可有不同程度的改善。但若光凝不足,有时反而会促进新生血管增生。若新生血管位于黄斑中心凹,则不能光凝。
Degeneration, inflammation, trauma and other various causes of subretinal retinal neovascularization invasion, can occur subretinal hemorrhage, this article only describes several common diseases. Due to the different nature of subretinal neovascular disorders, clinical findings are also slightly different, but their common feature is: the formation of disc-shaped macular degeneration lesions. Fluorescent fundus fluorescein angiography can detect the location of neovasculature, size and permeability, which determine the treatment program is essential. Etiology of these diseases can be tried, but no positive result. Opponents new blood vessels, a variety of laser photocoagulation is the only active therapy. Therefore, early detection of new blood vessels, early laser treatment, and sometimes have different degrees of visual acuity improved. However, if insufficient photocoagulation, sometimes it will promote neovascularization. If the neovascularization in the fovea, you can not photocoagulation.
