目的 了解隐斜视与调节性集合/调节比值(AC/A)、调节滞后量之间的关系,探讨隐斜视在近视发生发展中的可能作用.方法 横断面研究.选取近视伴隐斜视青少年62例,检测其屈光度、近距离水平隐斜度及AC/A、调节滞后量.按低、中、高度近视分组,分别对这3组中内隐斜患者与外隐斜患者的AC/A、调节滞后量进行比较,并对隐斜度与AC/A、调节滞后量进行相关性分析.结果 低度近视组内隐斜患者的AC/A、调节滞后量分别为(4.72±0.38) △/D、(-0.50± 0.20)D,外隐斜患者分别为(3.4±0.31)△/D、(-0.20±0.10)D;中度近视组,内隐斜患者的AC/A、调节滞后量分别为(4.25±0.55) △/ID、(-0.58±0.12)D,外隐斜患者分别为(3.26±0.25)△/D、(-0.30±0.13)D;高度近视组,内隐斜患者的AC/A、调节滞后量分别为(3.63±0.21)△/D、(-0.60±0.10)D,外隐斜患者分别为(2.50±0.29)△/D、(-0.28±0.12)D;3组中内隐斜患者与外隐斜患者的AC/A及调节滞后量差异均有统计学意义.内隐斜度与AC/A呈正相关(r=0.670,P＜0.05),与调节滞后量呈正相关(r=0.430,P＜0.05);外隐斜度与AC/A呈负相关(r=-0.331,P＜0.05),与调节滞后量呈正相关(r=0.423,P＜0.05).结论 近视患者中,内隐斜的AC/A、调节滞后量均大于外隐斜.内隐斜可能比外隐斜更易促进近视发展,隐斜度越大,近视发展越快.较大度数的外隐斜因伴随较大的调节滞后量对近视发生、发展起重要作用.

Objective To explore the relationship of accommodative convergence/accommodation (AC/A) and accommodative lag,and learn the possible role of heterophoria in the development of the myopia.Methods It was a cross-sectional study.We selected the juvenile myopes with heterophoria 62 persons(124 eyes) in all,tested their diopter,the degree of horizontal phoria,AC/A and accommodative lag.According to the tow,medium and high myopia,we divided them into three groups,and compared the AC/A,accommodative lag of esophoria with exophoria in these three groups and in the meantime,the heterophoria with AC/A and accommodative lag is analyzed.Results In low myopia group,AC/A and accommodative lag in esophoria is (4.72±0.38)△/D,(0.50±0.20)D respectively,and in exophoria,is (3.45±0.31)△/D,(0.20±0.10)D respectively.In moderate myopia,AC/A and accommodative lag in esophoria is (5.33±0.42)△/D,(0.58±0.08)D respectively,and in exophoria,is (3.26±0.25)△/D,(0.30±0.13)D respectively.In high myopia,AC/A and accommodative lag in esophoria is (4.01 ±0.38)△/D,(0.50±0.12)D respectively,and in exophoria,is (2.50±0.29)△/D,(0.28±0.12)D respectively; both between AC/A and accommodation lag are statistically significant difference (P＜0.05).The esophoria degree correlation positively with AC/A (r=0.670,P＜0.05)and accommodation lag (r=0.430,P<0.05).The exophoria degree correlation negatively with AC/A (r=-0.331,P＜0.05),and correlation positively with accommodation lag (r=0.423,P＜0.05).Conclusion In myopia patients,AC/A and accommodation lag in esophoria are greater than exophoria,and the esophoria degree correlation positively both with AC/A and accommodation lag,so we speculate that the patients with esophoria their degree of myopia development more quickly than exophoria,the greater the degree of esophoria,the quicker the degree of myopia developments.The exophoria degree correlation negatively with AC/A,and correlation positively with accommodation lag,so we surmise that the large degree of exophoria plays an important role in the development of myopia through the bigger accommodative lag.
