摘要
目的观察比较屈光不正及屈光参差对弱视患儿立体视功能发育的影响。方法63例经治疗后双眼矫正视力均达1．0以上的屈光不正或屈光参差性弱视患儿，根据初诊时散瞳检影验光the resuh of retinoscopy after mydriasis的结果分为A组（屈光不正组）41例、B组（屈光参差组）22例；另外根据患儿初诊年龄分为a组（≤3岁）7例、b组（3-6岁）47例、c组（〉6岁）9例。同视机及颜少明《立体视觉检查图》分别测量其远、近立体视。统计各组的远、近立体视差异。结果63例患儿中分别有19例（S0．2％）、5例（7．9％）获得了正常的远、近立体视。A组41例，16例有正常的远立体视（占39．0％），4例有正常的近立体视（占9．7％）。B组22例，3例存在正常的远立体视（占14．3％），仅1例有正常的近立体视（4．5％）。两组之间远立体视的差异有统计学意义（X^2=4．38，P〈0．05），近立体视的差异无统计学意义（P〉0．05）；a、b、c三组中a、b两组及a、c两组远立体视的差异有统计学意义（r=7．41，P〈0．01；P〈0．05），各组之间近立体视的差异均无统计学意义；但63例患儿的远、近立体视获得率之间的差异具有显著的统计学意义（x^2=10．56，P〈0．01）。结论经治疗矫正视力已达正常的弱视患儿的立体视功能仍未完全恢复正常。屈光不正、屈光参差均会影响弱视患儿的立体视功发育，但屈光参差性弱视更严重。初诊年龄亦影响弱视患儿的立体视功发育，因此弱视应尽早治疗。
Objective To investigate and compare the differences between ametropic and anisometropic amblyopia stereoscopic function of children with. Methods Sixty-three ametropic or anisometropic amblyopia children whose corrected visual acuity was recovered to normal were included. According to the result of retinoscopy after mydriasis in the first visit, the patients were divided into two groups： Group A （ametropia group, 41 cases） and Group B （Anisometropia group, 22 cases）. In addition, according to first visit age of the children, they were divided into 3 groups： Group a （≤3 years old, 7 cases）, Group b （3- 6 years old） 47 cases, and Group c （≥6 years old） 9 cases. Synoptophore and Yan Shaoming Stereoscopic Vision Control Chart were used to examine their far and near stereoscopic respectively. The statistically differences between far and near stereopsis were analyzed among the groups. Results Nineteen children owed the normal far stereoscopic and 5 owed the normal near stereoscopic among the 63 cases. Sixteen children （39.0%） of Groups A and three children （14.3%） of Groups B owned the normal far stereoscopic, and differences between the two groups showed statistical significance （P 〈0.05）. Four （9.7%） children got the normal near stereoscopic in Group A, and one （4.5%） in Group B. Differences between the two groups did not show any significant （P 〉0.05）. In the three groups of a, b, and c, the far stereoscopic differences between a and b and between a and c showed statistical significance （P 〈0.01, P 〈0.05）, but the far stereoscopic difference between b and c has no significant （P 〉0.05）. The near stereoscopic differences among the three groups had no significant （P 〉0.05）. After treatment, among the 63 cases of amblyopia children 19 （30.2%） got the normal far stereoscopic vision and only five （7.9%） got the near stereoscopic vision, there were statistically significant difference between far and near stereoscopic vision （P 〈 0.01）. Conclusions After treatment, although the children obtain the normal visual acuity, not all of them recover normal stereoscopic vision. Both arnetropia and anisometropia do：harm to the stereo visual function of children, however, the anisometropia particularly. The first visit age also has effect on the stereo visual function of children, thus the amblyopia children should receive treatment as soon as possible.
