本文对104例(188眼)高度近视(-6.00D以上)眼底后极部病变进行临床研究表明,后巩膜葡萄肿是本病眼底的一种基础性病变,发生率为77.36％,分为黄斑型,盘周型,盘-斑型。脉络膜视网膜萎缩分为三期:色素上皮萎缩,脉络膜毛细血管萎缩,脉络膜大中血管萎缩。其发生与眼轴变长,近视加重及年龄增长正相关。漆纹样裂纹是导致黄斑出血和视网膜下新生血管的重要因素,它与Fuchs斑关系密切。后巩膜葡萄肿是本病进展阶段的主要早期体征。脉络膜视网膜萎缩则是本病变性阶段的重要标志。上述病变对患者视功能构成进行性损害。
In this paper, 104 cases (188 eyes) of high myopia (-6.00D above) fundus posterior pole lesions of clinical studies show that posterior staphyloma is the fundus of the disease a basic disease, the incidence was 77.36%, divided into macular Type, disk type, disk - spot type. Chorioretinal atrophy is divided into three phases: pigment epithelial atrophy, choriocapillaris atrophy, choroidal atrophy. The occurrence of axial length, myopia increased and age is positively correlated. Lacquer-like cracks are an important factor leading to macular hemorrhage and subretinal neovascularization and are closely related to Fuchs plaque. Posterior staphyloma is the main early stage of disease progression. Chorioretinal atrophy is an important hallmark of this degenerative stage. The above lesions on the composition of patients with visual impairment.
