BACKGROUND
To compare binocular functions in amblyopic and non-amblyopic anisometropes and to investigate the possible associated factors for amblyopia development such as type of refractive error and initial age of refractive error correction.
MATERIALS AND METHODS
Prospectively anisometropic subjects with (n=42) and without amblyopia (n=33) were included in the study. Full ophthalmological examination including binocularity and motility was performed.
RESULTS
There was no statistically significant difference between the ages at the time of initial refractive error correction (P =0.946). All of the anisometropes (100%) had fusion with Worth 4-dot test and Bagolini glasses. However 81% of amblyopic subjects had fusion with Worth 4 dot test and 88.1% had normal response with Bagolini glasses. Median stereopsis was 60 sec of arc in anisometropic subjects and 400 sec of arc in amblyopes.
CONCLUSION
Our data support that, binocular functions are well developed in anisometropes without amblyopia and initial age at correction of refractive error has no primary effect on development of amblyopia.
背景
比较弱视和非弱视屈光参差者的双眼功能，并研究可能与弱视发展相关的因素，如屈光不正的类型和屈光不正矫正的初始年龄。
材料与方法
本研究前瞻性纳入了（n=42）伴有和不伴有弱视的（n=33）屈光参差患者。进行了全面的眼科检查，包括双眼视和眼球运动。
结果
初始矫正屈光不正的年龄无统计学差异（P=0.946）。所有屈光参差患者（100%）均通过 Worth 4 点测试和巴多林氏镜融合。然而，81%的弱视患者通过 Worth 4 点测试融合，88.1%的患者巴多林氏镜检查结果正常。在屈光参差者中，中位立体视锐度为 60 弧秒，在弱视者中为 400 弧秒。
结论
我们的数据支持这样的观点，即无弱视的屈光参差者的双眼功能发育良好，屈光不正矫正的初始年龄对弱视的发展没有主要影响。
