【摘要】 目的:观察双眼视觉训练对功能性视力不良的疗效。方法:回顾性系列病例研究。选取2018-01/06我科就诊的患儿22例(男12例,女10例),平均年龄7.5±0.8岁,完善眼部常规检查及屈光、双眼视觉功能检查。对屈光度数为球镜在±1.00D以内之间、伴有低于1.00D散光或不伴散光者,根据结果行针对性视觉功能训练。观察训练前后视力、屈光度及双眼视功能。结果:训练后22例患儿视力均有提升,训练前后平均屈光度分别为-0.011±0.573、-0.057±0.338D(P=0.633)。远距离水平隐斜量训练前后的平均值分别为-3~△±2.97~△和-1.18~△±1.6~△(P=0.089)。训练前后近距离水平隐斜量平均值分别为-6.27~△±4.56~△及-2.82~△±2.56~△;集合近点平均值分别为7.73±2.15、3.05±0.69cm;调节性集合与调节比率平均值分别为2.00±1.55、3.64±0.5 (均P<0.05)。训练前双眼视觉的负相对调节及正相对调节的平均值分别为1.61±0.41、-1.98±0.71D,训练后为2.09±0.23、-3.89±0.71 D;训练前后调节反应由0.09±0.38D提升至0.39±0.13D;调节幅度由9.55±2.54D到11.55±1.13D;双眼调节灵敏度由3.36±2.73cpm到9.64±1.5cpm(均P<0.05)。结论:儿童功能性视力不良者,在屈光检查的前提下,进行双眼视觉功能检查是必要的;针对性视觉训练治疗,可以提高视力及改善双眼调节及集合功能。更多还原

【Abstract】 ?AIM: To observe the curative effect of vision therapy on children with functional visual loss.?METHODS: Totally 22 children with functional vision loss were enrolled in our department between January 2018 and June 2018, including 12 males and 10 females, the mean age 7.5±0.8 years old. All patients had routine eye examinations, refraction and binocular visual function examinations. Children with or without astigmatism whose diopter spherical mirror was between±1.00 D and were accompanied by astigmatism less than ±1.00 D participated in personalized vision therapy. Paired t test was used to analyze the binocular visual function before and after vision therapy.?RESULTS: The average visual acuity of the 22 children were improved, but the diopters before and after vision therapy were-0.011±0.573 D and-0.057 ±0.338 D drespectively, without statistical significance（P=0.633）. The average of the distant level phoria（DLP） before and after vision therapy were-3^△ ±2.97^△ and-1.18^△ ±1.6^△, which was not statistically significant（P=0.089）. The near level phoria（NLP） were-6.27^△ ±4.56^△ and-2.82^△ ±2.56^△; the near point of convergene（NPC） were 7.73±2.15 and 3.05±0.69 cm; the accommodation convergence/accommodation（AC/A） were 2.00±1.55, 3.64±0.5 before and after the training respectively（P<0.05）; The negative relative accommodation（NRA） and positive relative accommodation（PRA） before vision therapy were 1.61±0.41 and-1.98±0.71 D; after training they were 2.09±0.23 and-3.89±0.71 D respectively; binocular crossed-cylinder（BCC） was 0.09±0.38 D, which improved to 0.39±0.13 D after therapy; the average of amplitude of accommodation（AMP） were 9.55±2.54 and 11.55±1.13 D; binocular accommodation facility（BAF） were 3.36±2.73 and 9.64±1.5 cpm respectively before and after therapy.?CONCLUSION:It is necessary to perform binocular visual function examination base on the refractive examination for children with functional vision loss. Visual therapy can improve visual acuity and binocular vision function.更多还原
