中文摘要：

近视眼系光线成像于视网膜之前的重要致盲眼病之一。近视眼的发病有明显的遗传因素。迄今用分子遗传学方法对近视眼相关基因进行染色体定位，但尚未发现明确的致病基因。作者就近年来近视眼相关基因的染色体定位、候选基因的筛查等研究作一综述。

英文摘要：

Myopia is an important cause of blindness, in which an image retina. Genetic factors have been implicated in the pathogenesis of myopia. Based is focused in front of the study, some genetic loci linked to myopia have been mapped, but no disease-causing identified. Here authors review the genetic study on myopia, including gene mapping and screening. olecular genetic gene has been candidate gene
