一、视网膜分支静脉阻塞的研究进展视网膜分支静脉阻塞是视力减退的常见原因之一。它常发生于视网膜动静脉交叉处。动脉为原发性或继发性损害。好发部位是颞侧视网膜静脉分支,特别多见于老年人。视网膜颞上或颞下支静脉阻塞后,对黄斑功能都是威胁:在急性期,受害静脉怒张、迂曲、色暗。出血及广泛的视网膜水肿,在黄斑尤为明显。如果水肿严重而持久,在后极部引起浆液性视网膜脱离。视网 First, the research progress of retinal branch vein occlusion Retinal branch vein occlusion is one of the common causes of vision loss. It often occurs in the retinal artery vein intersection. Artery is primary or secondary damage. The site of predilection is temporal retinal vein branches, especially common in the elderly. Retinal temporal or superior temporal vein occlusion, the macular function is a threat: in the acute phase, the victim vein engorgement, tortuous, dark color. Bleeding and extensive retinal edema, especially in the macula. If the edema is severe and persistent, it causes serous retinal detachment in the posterior pole. Network
