原发性视网膜动静脉交通支(AVCR)的形成,通常认为属于稳定的病变,不引起眼部并发症。作者报道了7例AVCR患者发生视网膜内的黄斑出血、视网膜中央和周边静脉阻塞、新生血管性青光眼,以及玻璃体出血等眼部并发症。在这7例中,有1例黄斑出血,3例自发性玻璃体出血。其中1例继发于缺血性视网膜周边静脉阻塞病引起的新生血管形成,1例继发于视网膜中央静脉阻塞,1例无任何明显的诱发原因。2例年轻患者在AVCR区发现周边静脉阻塞性病变,其中1例与AVCR部分消退有关。有3例发生视网膜中央静脉阻塞,其中2例发生新生血管性青光眼,用全视网膜
The formation of primary retinal artery and vein traffic branch (AVCR) is usually considered stable and does not cause ocular complications. The authors report ocular complications such as macular hemorrhage in the retina, occlusion of the central and peripheral retinal veins, neovascular glaucoma, and vitreous hemorrhage in seven patients with AVCR. In these 7 cases, there was 1 case of macular hemorrhage and 3 cases of spontaneous vitreous hemorrhage. One case was secondary to neovascularization caused by ischemic retinal occlusive disease, one case was secondary to central retinal vein occlusion, and one case had no obvious cause. In 2 young patients, peripheral venous obstructive lesions were found in the AVCR region, of which 1 was partially related to AVCR regression. There were 3 cases of central retinal vein occlusion, of which 2 cases of neovascular glaucoma, the whole retina
