视网膜下新生血管(subretinal neovascularization)不同于视网膜新生血管,是由脉络膜新生血管而来的纤维血管组织,可见于各种黄斑病中。由于它严重地损害中心视力,目前已成为许多国家致盲的主要原因之一。为引起我国临床工作者的警惕与重视,现将其临床表现、病理、发病机理及治疗方法综述如下,以供参改。一、临床表现(一)症状与体征:非活动性视网膜下新生血管很少引起主觉症状。视网膜下新生血管一旦发生渗漏或破裂,视力可突然减退,视物变形
Subretinal neovascularization, unlike retinal neovascularization, is a fibrovascular tissue derived from choroidal neovascularization and is found in various maculopathies. Since it seriously damages central vision, it has become one of the main causes of blinding in many countries. In order to arouse the vigilance and attention of clinicians in our country, the clinical manifestations, pathology, pathogenesis and treatment methods are summarized as follows for reference. First, the clinical manifestations (a) symptoms and signs: Inactive subretinal neovasculature rarely cause symptoms. Subretinal neovascularization in the event of leakage or rupture, visual acuity may suddenly diminished, visual distortion
