目的通过测量调节滞后量和眼位,研究在不同调节刺激下,患者反应性AC/A和刺激性AC/A的相关性.方法横断面研究.选择在校大学生29例,在全矫基础上,利用棱镜分离法测量被检者[平均年龄(23.3±3.8)岁,除近视外,无其他眼部及全身疾病]在5 m和40 cm处的隐斜量.在全矫度数的基础上添加+1.00、+1.50、-1.00、-2.00 D球镜,重新检查被检者在40 cm处的隐斜视,应用MEM动态检影法测量患者的调节滞后量.采用秩和检验对数据进行统计分析.结果在不同的调节刺激下,患者的调节滞后量、梯度法反应性AC/A及梯度法刺激性AC/A的差异均有统计学意义(x2=116.85、8.992、17.319,P＜0.05).基于梯度法得到的反应性AC/A与刺激性AC/A均呈正相关(+1.00 D:r=0.542,P＜0.01；-1.00 D∶r=0.789,P＜0.01；-2.00 D∶r=0.812,P＜0.01).基于计算法得到的反应性AC/A与刺激性AC/A也呈正相关(r=0.859,P＜0.01).结论附加负球镜时,调节滞后量更大.计算法求的反应性AC/A与刺激性AC/A的相关性最好.

Objective To study the correlation between the stimulus and response AC/A ratios by measuring a patient's accommodative lag and eye position using different stimuli to induce accommodation.Methods A cross-sectional study was used.Twenty-nine myopic college students (average age 23.3±3.8) were randomly selected for the study.Phoria was measured at distances of 40 cm and 5 m by prism separation when wearing full correction.Phoria was measured again at a distance of 40 cm after adding spherical lenses of +1.00 D,+1.50 D,-1.00 D and-2.00 D.Accommodative lag was then measured with each lens power by the monocular estimation method using dynamic retionscopy.Finally,the data were analyzed by a rank-sum test.Results There were statistically significant differences between accommodative lag and gradient response and stimulus AC/A ratios when different accommodative stimuli were used (x2=116.85,8.992,17.319,P＜0.05).The correlation coefficients between response and stimulus AC/A ratios based on the gradient method were 0.542 (P＜0.01),0.789 (P＜0.01),and 0.812 (P＜0.01) with added lenses of +1.00 D,-1.00 D,-2.00 D.And the correlation coefficient between response and stimulus AC/A ratios based on the calculation method was 0.859 (P＜0.01).Conclusion A subject has less accommodative response and more accommodative lag with minus spherical addition than with a plus spherical addition lens.The correlation between stimulus and response AC/A ratios is highest when using a calculation method.
