Abstract

We studied 436 eyes of 218 patients with myopia of -6.00 diopters or more in both eyes. Of 218 patients, 72 (33.0%) had lattice degeneration of the retina. Among these 72 patients, lattice lesions were uniocular in 39 (54.2%) and binocular in 33 (45.8%). Of 105 males, 33 (31.4%) had lattice degeneration; of 113 females, 39 (34.5%) had lattice degeneration. Contrary to previously published data, we found an inverse relationship between axial length and the prevalence of lattice degeneration in severely myopic eyes. The greatest prevalence of lattice degeneration (63 of 154 eyes, 40.9%) was found in eyes with an axial length of 26.0 to 26.9 mm (-6.00 to -8.70 diopters), and the least prevalence of lattice degeneration (five of 71 eyes, 7.0%) was found in eyes with an axial length of 32.0 mm (-24.00 diopters) or greater. This may explain the observation that retinal detachment after cataract surgery has been noted more commonly among patients with moderate than severe myopia.

摘要

我们研究了218例双眼近视度数均为-6.00屈光度或更高的患者的436只眼睛。在这218例患者中，72例（33.0%）存在视网膜格子样变性。在这72例患者中，格子样病变单眼发生的有39例（54.2%），双眼发生的有33例（45.8%）。在105例男性中，33例（31.4%）存在格子样变性；在113例女性中，39例（34.5%）存在格子样变性。与先前发表的数据相反，我们发现在高度近视眼轴长度与格子样变性患病率之间呈负相关。格子样变性患病率最高的是眼轴长度为26.0至26.9毫米（-6.00至-8.70屈光度）的眼睛（154只眼中有63只，40.9%），而患病率最低的是眼轴长度为32.0毫米（-24.00屈光度）或更长的眼睛（71只眼中有5只，7.0%）。这可能解释了如下观察结果：白内障手术后视网膜脱离在中度近视患者中比在高度近视患者中更常见。
