背景研究表明,作为非光学因素,认知对调节系统存在一定的影响,因此客观、准确的实验设计是评价非光学因素对调节系统影响的关键步骤之一. 目的研究视标呈现方式和注视方式对调节及调节微波动的影响,并进一步探讨认知中专注注视这一高水平注意因素对调节系统影响及近距离工作下专注注视的注视状态与近视发生发展的可能关系.方法选择健康志愿者30例,平均年龄(24.80±1.98)岁,平均等效屈光度为(-1.92±2.02)D,平均柱镜屈光度为(-0.19±0.58)D.所有测量在屈光全矫下进行.采用开放视野红外自动验光仪测量受试者双眼注视40 cm处随机呈现的不同视标注视状态下右眼的调节反应.视标设计为专注注视状态和放松注视状态. 结果受试者在专注注视状态下的调节反应均值为(1.86±0.26)D,放松注视状态下的调节反应均值为(1.27±0.39)D,差异有统计学意义(t=-8.052,P=0.000).受试者在专注注视状态下的调节微波动均值为(0.17±0.06)D,放松注视状态下的调节微波动均值为(0.28±0.17)D,差异有统计学意义(t=3.600,P=0.001).结论视标的呈现方式和注视方式可影响调节反应,专注注视这一高水平注意因素使调节系统的调整更加精确、稳定.

Background Researches showed that as the non-optical factors,cognitive has certain influence on the regulating system.So accurately experimental design is one of the key steps that evaluates the non-optical factors on regulating system.Objective The present study was to investigate the influence of presenting pattern of target and watching way on the level and amplitude of accommodative fluctuate and to analyze the effect of focus gaze of cognitive on regulating system and the relationship between focus gaze condition under near work and the development of myopia.Methods This study complied with Declaration of Helsinki,and the permission of Ethic Committee and written informed consent was obtained before entering in this trial.Thirty healthy volunteers were included with the mean age (24.80 ± 1.98) years old,equivalent refractive diopter (-1.92 ± 2.02) D and mean cylinder (-0.19±0.58) D.The presenting pattern of the targets was designed as focus gaze and relaxed gaze.The accommodative response and accommodative fluctuation in the complete corrected right eyes for the different targets at the 40 cm under the gazing state was recorded with Grand Seiko WAM 5500 automatic infrared refractor in the experiment.Results The mean accommodative response value was (1.86±0.26) D under the focus gaze and (1.27±0.39) D under the relax gaze,showing a statistically significant difference (t=-8.052,P=0.000).The mean fluctuate value was(0.17±0.06) D under the focus gaze,with a significant lowing in comparison with (0.28±0.17) D under the relax gaze (t =3.600,P =0.001).Conclusions These results demonstrate that the different presenting patterns of sighting target and watching ways of the subjects affect accommodation system.The accommodative response was relatively more accurate with a smaller microwavc moving under the focus gaze condition.
