摘要目的 探讨视知觉学习治疗近视性弱视过程中患儿屈光度的变化及护理特点.方法 选择2007至2009年行视知觉学习治疗的近视性弱视患儿54例(98眼),收集治疗前后球镜、柱镜和等效球镜,并对不同程度弱视眼屈光变化进行比较.结果 视知觉学习治疗过程中近视性弱视患儿球镜年均增长0.52D,散光年增长0.03D;等效球镜年均增长在0.50D以内占57.14%;轻、中、重度弱视患儿的球镜和等效球镜变化有差异,但柱镜变化比较无显著差异.结论 视知觉学习治疗近视性弱视对患儿的屈光度增长影响甚微,但在治疗过程中仍需密切关注患儿近视屈光度变化.

abstractsObjective To investigate the refraction change and nursing character in myopic amblyopia during the perceptual learning treatment. Methods Refraction of 54 children (98 eyes) with myopic amblyopes were selected,which were selected from the amblyopia clinic between 2007 and 2009, the spherical diopter, astigmatism and spherical equivalent were collected before and after perceptual learning,the refractive dynamic was compared according to the degree of amblyopia. Results The spherical average annual growth of myopic amblyopia during treatment was 0.52D, the growth of astigmatism was 0.03D;the spherical equivalent average annual growth was less than 0.50D accounted for 57.14%. The dynamic changes of spherical or SE of mild, moderate and severe amblyopia had significant difference, but the cylinder had not significant difference in change. Conclusions The treatment of perceptual learning in patients has little effect on the growth of refraction in myopic amblyopia, however, it is still necessary to pay close attention to refraction changes of in myopic amblyopia in the course of treatment.
