目的探讨凸透三棱镜结合视觉生理性眼操训练对青少年近视的预防控制作用。方法散瞳检查为低度近视或正视眼,双眼水平隐斜<8△的7～14岁青少年106例,按随机数字表法分为观察组和对照组,每组53例。两组近视屈光度≥-1.00D者配戴远用近视镜,近视屈光度<-1.00D及正视者不配戴远用近视镜。所有患者看近学习及看电脑时均配戴下加+1.50～+2.00D基底朝内的凸透三棱镜。观察组给予生理性眼操训练干预,每天做两次训练,每次3min。对照组不进行眼操训练干预。于干预前、干预后2a测定两组屈光度、眼轴及隐斜度。结果干预后观察组近视屈光度增加-(0.81±0.42)D、眼轴长度增加(0.23±0.21)mm,均低于对照组的-(1.17±0.46)D及(0.32±0.19)mm(均为P<0.05);观察组近隐斜度无明显改变:干预前为-(5.07±2.78)△,干预后为-(4.89±2.34)△(t=0.361,P=0.719),对照组近外隐斜度有所增加:干预前为-(5.29±2.63)△,干预后为-(6.43±2.78)△(t=2.169,P=0.033),干预前后两组远隐斜度无明显改变(观察组t=0.185,P=0.854;对照组t=0.045,P=0.964)。结论近用凸透三棱镜结合视觉生理性眼操训练能更有效预防及控制青少年近视发展,同时对长期使用凸透三棱镜所产生的外隐斜增大有预防作用。
Objeetive To explore the clinical effect of prevention and control of a convex prism lens and the visual physiological finger exercise on teenage myopia. Methods A total of 106 teenage of 7 to 14 years old who had low myopia or normal vision and heterophoria 〈8△ after pupil examination,were randomly and equally divided into 2 groups. Those with diopters ≥ - 1.00 D wore myopia glasses and the others did not wear myopia glasses in two groups. All of them were asked to wear the convex prism lens base whose diopter were from ＋ 1.50 D to ＋ 2.00 D when they studied close by or played computers. Observation group was treated with visual physiological finger exercise,two times a day and 3 minutes each time, while the control group did not do the visual physiological finger exercise. At 2 years before and after intervention, myopia diopter, ocular axis and heterophoria were measured. Results The changes of myopia diopter - （0.81 ± 0.42） D and ocular axis （ 0.23 ± 0.21 ）mm in observation group both were respectively lower than those of control group - （ 1. 17 ± 0. 46 ） D and （ 0. 32 ± D. 19） mm （ both P 〈 0.05 ）. Myopia heterophoria of observation group did not change obvionsly：before intervention - （ 5. 07 ± 2. 78 ） a, and after intervention - （ 4. 89 ± 2. 34） a （ t =0. 361 ,P =0. 719）. Near heterophoria of control group increased a little：before intervention - （5.29 ± 2.63 ） a ,and after intervention - （6.43 ± 2.78 ） △ （ t = 2. 169,P =0. 032）. Far heterophoria of the two groups before and after intervention did not change obviously（ observation group t = 0. 185,P = 0. 854 ; control group t = 0.045,P = 0.954）. Conclusion Wearing the near convex prism lens combined with the visual physiological finger exercise can effectively prevent and control teenage myopia,and can prevent far heterophoria＇ s increasing induced by long-term wearing of the convex prism lens.
