弱视发生于出生后视觉系统的发育时期,从视网膜到大脑视觉中枢的功能性发育异常,临床主要表现为视网膜视力的低常。从临床角度将弱视的病因分为两类:末梢性和中枢性。末梢性弱视是由于视网膜以前的视光通路异常所致;中枢性弱视则是因双眼视觉信息紊乱如复视、混淆视及像差等,大脑不能将双眼的视觉信息进行融合,从而出现单眼弱视。 Amblyopia occurs at the developmental stage of the postnatal visual system, from the retina to the functional development of the visual center of the brain abnormalities, the main clinical manifestations of retinal vision is often low. The clinical causes of amblyopia will be divided into two categories: peripheral and central. Distal amblyopia is due to the anterior retinal abnormalities caused by the optic path; central amblyopia is due to binocular visual information disorders such as diplopia, confusion and aberrations, the brain can not be the integration of the visual information of both eyes, resulting in monocular amblyopia .
