ABSTRACT
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 amplitude9.69 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 lagP=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.
