目的 通过对弱视的Ⅲ级视功能异常的观察 ,旨在强调在弱视的诊治中 ,不仅注意视力的提高 ,而且要重视建立双眼 级视功能。方法 通过扩瞳、检影、验光确诊为弱视的 10 3例 4岁以上患者 ,用同视机检查Ⅲ级视功能。结果 屈光不正性弱视中 , 级视功能正常 73.3% ;出现双眼交替性抑制点 2 6 .7%。斜视性弱视中 ,内斜性弱视Ⅲ级视功能异常 72 .2 % ,外斜性弱视 级视功能异常 10 0 % ,屈光参差性弱视中 , 级视功能异常呈单眼抑制 5 5 % ,无融合功能或融合范围减小 70 % ,无立体视功能 40 %。结论 不同类型的弱视由于其发病原因不同 ,其 级视功能异常情况亦各不相同。对 级视功能异常的弱视应进行视功能训练 ,以提高疗效。
Objective To observe the abnormal visual function of grade Ⅲ amblyopia, and to emphasize that in the treatment of amblyopia, attention should be paid not only to the improvement of visual acuity, but also to the establishment of binocular grade visual function. Methods A total of 103 patients aged above 4 years old with amblyopia diagnosed by dilation, retinoscopy and optometry were examined with stereopsis for grade Ⅲ visual function. Results In ametropia amblyopia, the level of visual function was normal 73.3%; there were 26.7% of the two eyes alternating inhibitory point. Strabismic amblyopia, amblyopia grade amblyopia grade Ⅲ 72.2%, exotropia amblyopia grade dysfunction 10%, anisometropic amblyopia, grade amblyopia was monocular inhibition of 5 5%, no The fusion function or fusion range is reduced by 70% and there is no stereovision function by 40%. Conclusion Different types of amblyopia due to its different causes, the level of abnormal visual function is also different. Amblyopia of abnormal visual function should be visual function training to improve the efficacy.
