屈光参差是指两眼屈光度不同，其程度或性质有一定差别〔１〕。屈光参差是影响双眼单视，导致儿童弱视的常见原因之一。但多因一眼视力尚好，常造成漏诊，延误治疗时机。本文就屈光参差的研究方法、屈光参差对视功能的影响、屈光参差与弱视的关系及屈光参差的治疗等作一综... Refractive error refers to the two different refraction, the degree or nature of a certain difference [1]. Refractive error is one of the common causes of binocular vision, leading to amblyopia in children. However, due to a still good eyesight, often resulting in missed diagnosis, delay the timing of treatment. This article on the anisometropia research methods, anisometropia visual function, the relationship between anisometropia and amblyopia and anisometropia treatment and so on.
