【摘要】：目的:通过观察屈光性弱视患儿双眼视力达到正常时的融合功能及远、近立体视,分析影响屈光性弱视患儿治疗过程中双眼视觉发育的因素。方法:通过回顾性队列研究,选择1998年3月至2016年11月青岛大学附属医院眼科收集收治的164例经治疗双眼矫正视力达1.0的屈光不正和屈光参差性弱视患儿,在此样本中男82例,女82例,初诊年龄为3.0至12.0岁,平均年龄为4.86±0.71岁,视力恢复正常年龄为5.4至13.0岁,平均年龄为6.79±1.23岁,所有弱视患儿均经常规眼科检查,通过颜少明编写《数字化立体视觉检查图》(Digital stereoscopic test chart,DSTC)检测患儿近立体视,同视机随机点立体视画片(random-dot stereosgrams,RDS)检查融合和远立体视,记录患儿性别、初诊年龄、视力恢复正常年龄、治疗持续时间、弱视程度、是否采取遮盖、单眼或双眼弱视,采用X2检验、确切概率法和Kruskal-Wallis秩和检验,统计分析这些因素与融合功能及远、近立体视觉的关系。结果:1.164例患儿中,患儿初诊年龄、视力恢复正常年龄、治疗持续时间、弱视程度均对近立体视的恢复有影响(χ2=8.220、9.338、4.931、7.615,P均0.05),患儿性别、是否采取遮盖、单眼或双眼弱视对近立体视的恢复结果差异无显著性(χ2=0.994、2.836、0.187,P均0.05)。2.164例患儿样本中,患儿性别、初诊年龄、视力恢复正常年龄、弱视程度、治疗持续时间、是否采取遮盖、单眼或双眼弱视对远立体视的恢复影响均无显著性差异(P均0.05)。3.164例患儿中,患儿性别、初诊年龄、视力恢复正常年龄、治疗持续时间、弱视程度、是否采取遮盖、单眼或双眼弱视对融合功能的恢复影响均无显著性差异(P均0.05)。4.远立体视基本同步视力恢复,近立体视尚未随之同步恢复。结论:1.患儿初诊的年龄愈小、视力恢复正常的年龄愈小、治疗持续时间愈短、弱视程度较轻,越有利于近立体视的恢复,患儿性别、单眼或双眼弱视、是否采取遮盖对近立体视的恢复则无影响。2.患儿性别、初诊年龄、视力恢复正常的年龄、治疗持续时间、弱视程度、是否采取遮盖、单眼或双眼弱视对远立体视及融合的恢复均无影响。弱视患儿治愈后,融合均有不同程度的恢复,但仍低于正常水平。3.远立体视的恢复好于近立体视的恢复。
[Abstract]:Objective: to investigate the binocular visual development in children with ametropia amblyopia by observing the fusion function, distant vision and near stereopsis when the vision of children with refractive amblyopia reached normal level, and to analyze the factors affecting the development of binocular vision in children with refractive amblyopia. Methods: a retrospective cohort study was conducted in 164 children with ametropia and anisometropic amblyopia whose binocular corrected visual acuity reached 1.0 from March 1998 to November 2016 in the affiliated Hospital of Qingdao University. There were 82 males in this sample. 82 cases of female were diagnosed at the age of 3.0 to 12.0 years old, the average age was 4.86 卤0.71 years old, the normal visual acuity was 5.4 to 13.0 years old, the average age was 6.79 卤1.23 years old. All the children with amblyopia underwent routine ophthalmic examination. Using Yan Shaoming to compile "Digital Stereo Vision Diagram" (DSTC) to detect the near stereopsis of children, random dot stereopsis film (random-dot stereopsis) to check fusion and distant stereopsis, to record the gender, the age of first visit, the visual acuity to return to normal age, to record the sex of the child, the age of first visit, and the visual acuity to return to normal age. The duration of treatment, degree of amblyopia, whether or not to take cover, monocular or binocular amblyopia, X2 test, exact probability method and Kruskal-Wallis rank sum test were used to analyze the relationship between these factors and fusion function and distant and near stereoscopic vision. Results among the 164 children, the age of first visit, the age of visual acuity, the duration of treatment and the degree of amblyopia had influence on the recovery of near stereopsis (蠂 ~ 2 = 8.220 / 9.338 / 4.931 / 7.615P, P = 0.05). There was no significant difference in the recovery of near-stereopsis between monocular and binocular amblyopia (蠂 ~ 2 / 0.994n = 2.836 / 0.187P). The sex, age at first visit, visual acuity return to normal age, degree of amblyopia, duration of treatment, whether or not to cover up, were all observed in the sample of monocular amblyopia and binocular amblyopia (蠂 ~ 2 = 0.994, 2.836, 0.187). There was no significant difference in the effect of monocular or binocular amblyopia on the recovery of far stereopsis (P = 0.050.3.164). Sex, age at first visit, age of visual recovery, duration of treatment, degree of amblyopia, whether to take cover or not. There was no significant difference in the restoration of fusion function between monocular amblyopia and binocular amblyopia (P < 0.05). Distant stereopsis basic synchronous vision recovery, near stereopsis has not yet recovered synchronously. Conclusion 1. The younger the first visit, the younger the age of recovery of visual acuity, the shorter the duration of treatment, the lighter the degree of amblyopia, the more favorable to the recovery of near stereopsis, the gender of the child, the amblyopia of monocular or binocular amblyopia. There was no effect on the restoration of near stereopsis by shading. 2. Gender, age at first visit, age at which visual acuity returned to normal, duration of treatment, degree of amblyopia, whether covered or not, and unilateral or binocular amblyopia had no effect on the recovery of distant stereopsis and fusion. After the amblyopia was cured, the fusion was recovered to some extent, but still lower than the normal level. 3. 3. The recovery of distant stereopsis is better than that of near stereopsis.
