背景主视眼是人类具有功能不对称行为的器官之一,它和非主视眼在很多方面的差异一直是基础研究和临床研究的热点,但基于成年近视患者调节功能方面的研究相对较少. 目的研究成年近视患者主视眼和非主视眼与调节相关各因素之间的关系.方法采用描述性系列病例观察的研究方法,纳入35例年龄为18～ 35岁、双眼屈光不正球镜度为-2.00 ～-10.00 DS、散光度≤1.50 DC且双眼屈光参差≤1.5 DS、最佳矫正视力(BCVA)≥1.0的单纯近视患者,采用卡洞法并结合拇指法判断主视眼的眼别,采用主观、客观综合验光法获得受检眼屈光不正的度数,用移近法测量单眼的调节幅度,以附加±0.50 D融合交叉柱镜(FCC)法测量受检眼的调节滞后情况,采用翻转法测量各眼的调节灵敏度. 结果本组患者的主视眼与非主视眼调节幅度分别为(9.69 ±2.30)D和(9.60±2.37)D,调节灵敏度分别为(11.08±4.20) cpm和(10.63±4.60) cpm,调节滞后量分别为0和0.25 D,主视眼与非主视眼间的差异均无统计学意义(P=0.294、0.260、0.141).右眼为主视眼的患者双眼调节幅度分别为(9.48±2.29)D和(9.33±2.49)D,调节灵敏度分别为(10.50±4.70)cpm和(9.99±4.90) cpm,差异均无统计学意义(P=0.319、0.116),双眼调节滞后量的差异无统计学意义(P=0.590).左眼为主视眼的患者双眼调节幅度分别为(9.91±2.35)D和(9.88±2.26)D,调节灵敏度分别为(10.70±3.77) cpm和(11.25±4.27) cpm,差异均无统计学意义(P=0.749、0.295),双眼调节滞后量间的差异无统计学意义(P=0.238).结论对于无或有较小屈光参差的成年近视患者,主视眼和非主视眼在调节幅度、调节灵敏度及调节准确性方面无差别.

Background Dominant eye is one of the functional asymmetric organ,and the dfference between dominant eye and undominant eye is a researching hotspot.But the study about accommodation in adult myopia is less.Objective This study was to determine the association between ocular dominances and accommodative factors in the subjects with adult myopia.Methods This study used prospective descriptive research method.Thirty-five subjects aged from 18 to 35 years with the myopia ranged from-2.00 D to-10.00 D and anisometropia less than 1.5 D,BCVA≥ 1.0 were recruited consecutively in this study.Ocular dominance was determined using the hole-inthe-card test and thumb test.Refractive error was measured with objective and subjective optometry,and amplitude of accommodation was measured by push-up test.Fusion cross cylinder(FCC) was used to measure the accommodative lag,and flipper test was applied to determine the accommodative facility.Oral informed consent was obtained from each subject before any relevant examination.Results No significant differences were found in the amplitude of accommodation (D),accommodative facility (cpm) and accommodative lag (D) between the dominant eye and undominant eye (accommodative amplitude:9.69 D±2.30 D vs.9.60 D±2.37 D,P =0.294 ;accommodative facility: 11.08 D±4.20 D vs.10.63 D± 4.60 D,P=0.260;accommodative lag:P=0.141).In the patients with the right eyes as dominance eyes,the accommodative amplitude of both eyes were (9.48±2.29) cpm and (9.33 ± 2.49) cpm,and accommodative facility were (10.50 ± 4.70) cpm and (9.99 ± 4.90) cpm.There were no significant differences between the right and left eyes in the accommodative amplitude,accommodative facility and accommodative lag (P =0.319,0.116,0.590).In the patients with the left eyes as dominant eyes,the accommodative amplitude of both eyes were (9.91±2.35)D and (9.88±2.26) D,and accommodative facility were (10.70±3.77)cpm and (11.25 ±4.27) cpm.No significant differences were seen between the right eyes and left eyes in the accommodative amplitude,accommodative facility and accommodative lag (P =0.749,0.295,0.238).Conclusions The amplitude of accommodation of the dominant eye is not significantly enhanced,and less accommodative lag and better accommodative facility also are found in the demonstrate eye in myopia adults with low anisometropia.
