摘要
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 in the early stage of visual system development after born,and there is functionally abnormal development from retina to optic center. Amblyopia shows the subnormal of the retina vision. Amblyopia is classified into two types： terminal and central. Terminal amblyopia is mainly caused by the abnormal optic route before retina; while central amblyopia is caused by the disorder optical message in the two eyes, such as diplopia, oonfused vision and aberration, etc, optical message of two eyes cannot be fused in the brain, and amblyopia occurs.
