视网膜格子变性和蜗牛迹变性是两种常见而具有牵拉作用的变性,都可能引起视网膜破口,常在同一眼出现。为探讨二种变性间的关系,作者检查了500例1,000只眼,患者年龄为8～66岁,男性320例,女性180例。患者屈光状态虽不同,却无眼底病症状。环绕周边眼底的格子变性呈孤立状视网膜变簿区,岛状晚期病变内有网状白线。单个蜗牛迹变性呈长形视网膜变薄区,边缘不规则,变性区内没有明显可见的白线。格子变性虽最常见,本组病例却有12只眼同时存在两种变性。有格子变性者62例(12.4%)87眼(8.7%),双眼者25例(40.32%)。17例(3.4%)27眼
Retinal plaid degeneration and snail degeneration are two common detritus that have a pulling effect, all of which can cause retinal tears, often in the same eye. To explore the relationship between the two degenerations, the authors examined 500 eyes of 1,000 eyes, aged 8 to 66 years, 320 males and 180 females. Although patients with different refractive status, but no fundus symptoms. Surrounding the fundus of the lattice degeneration was isolated retinal albumin area, island-shaped lesions within the white line. A single snail degeneration was elongated retinal thinning area, the edge of the irregular, denatured area there is no obvious white line. Although the most common lattice degeneration, this group of patients there are 12 eyes there are two degeneration. There were 87 eyes (8.7%) with lattice degeneration in 62 cases (12.4%) and 25 eyes (40.32%) in both eyes. 17 cases (3.4%) 27 eyes
