方法：选取2014-07/2015-04在我院医治的屈光参差性弱视患儿45例作为研究组，应用遮盖治疗，同期选取40例志愿健康者作为空白对照组，观察受试者的双眼视功能情况。

结果：遮盖治疗前、治疗1、3mo双眼融合正常率分别为62%、76%和87%，治疗3mo显著高于治疗前(P<0.05)，治疗1mo同治疗前差异不明显(P>0.05)； 遮盖治疗前、治疗1、3mo后立体视3000"～801"的患儿分别有26、13和2例； 800"～401"的患儿分别有12、13和6例； 400"～101"的患儿分别有7、15和25例； ≤100"者分别为0、4和12例； 研究组远距散开破裂点和辐辏功能治疗后均明显提升且高于对照组(P均<0.05)； 近距散开和辐辏功能破裂点、模糊点均较治疗前明显上升(均P<0.05)，散开功能破裂点、模糊点均高于对照组，辐辏功能中则低于对照组(均P<0.05)； 治疗后研究组双眼调节幅度、灵敏度均较治疗前显著提高(均P<0.01)； 双眼调节幅度显著低于对照组(均P<0.01)，调节灵敏度与对照组无差异(P>0.05)； 遮盖治疗后双眼调节滞后量较治疗前明显下降(P<0.05)，但同对照组相比无明显差异(P>0.05)； 研究组45例90眼治愈52眼； 进步24眼，无效14眼； 治疗总有效率为84%。

结论：屈光参差性弱视患儿遮盖调节对双眼视功能有一定改善。

METHODS: Forty-five children with anisometropic amblyopia of our hospital from July 2014 to April 2015 were as the study group, and treated by cover adjustment. Then 40 cases of healthy volunteers were selected as the blank control group. The binocular visual function of the subjects was observed.

RESULTS: Before treatments, at 1 and 3mo after treatments, the positive rates of binocular fusion were respectively 62%, 76% and 87%, which at 3mo after treatments was significantly higher than that before treatments(P <0.05). But the difference between that Before treatments and 1mo after treatments was not significant(P>0.05). Before treatments, at 1 and 3mo after treatments the numbers of children whose stereo visions were 3000 "～801" were respectively 26,13 and 2, and the numbers of children whose stereo visions were 800 "～401" were respectively 12,13 and 6; the numbers of children whose stereo visions were 400 "～101" were respectively 7,15 and 25; the numbers of children whose stereo visions were≤100" were respectively 0,4 and 12. Far apart from the point of rupture and the convergence function in the study group after treatments were improved and significantly higher than those in the control group(both P<0.05); the rupture points, fuzzy points of close out and convergence function were significantly higher than those before treatments(all P<0.05). The rupture points, fuzzy points of part out were higher than those of control group, while the convergence function was lower(all P<0.05).After treatments, the amplitude and sensitivity of both eyes in the study group were significantly higher than those before treatments(all P<0.01); the amplitude of both eyes was significantly lower than that in the control group P<0.01, and the sensitivity of both eyes had no difference with that in the control group(P>0.05). After cover adjustment treatment, the lag of binocular regulation significantly decreased than that before treatments(P <0.05), but there was no significant difference between the two groups(P>0.05). In the study group(45 cases with 90 eyes)52 eyes were cured, 24 eyes improved, 14 eyes ineffective; the total effective rate was 84%.

CONCLUSION: Cover adjustment has some improvement effect on binocular visual function in children with anisometropic amblyopia.
