Disagreement exists as to whether the depth of anisometropic amblyopia correlates with the degree of anisometropia. We reviewed the charts of 303 consecutive patients with the diagnosis of amblyopia. Thirty-five patients with untreated anisometropia without strabismus were identified. The best-corrected visual acuities, manifest refractions, and autorefractions were recorded. The differences in spherical equivalent, root mean square, and an index of anisometropia, which we defined, were calculated. The depth of amblyopia was strongly correlated to all three measures of anisometropia for both hyperopic and myopic individuals. Our new index of anisometropia was an excellent predictor of the depth of amblyopia.
关于屈光参差性弱视的深度是否与屈光参差程度相关，目前存在分歧。我们回顾了303例连续诊断为弱视患者的病历。确定了35例未经治疗的无斜视屈光参差患者。记录了最佳矫正视力、显验光和自动验光结果。计算了等效球镜度、均方根以及我们定义的屈光参差指数的差异。对于远视和近视个体，弱视深度与屈光参差的所有三种测量指标均密切相关。我们新的屈光参差指数是弱视深度的极佳预测指标。
