AIM:To analyse the relationship between amplitude of accommodation(AMP) and stereopsis and the different refractive status of college students.METHODS:Refractive data of 150 college students were performed objective and synthetic optometry and related binocular visual functional examination including stereopsis,AMP,et al.Refractive error data were converted into spherical equivalent (SE).According to myopia existence,students were divided into emmetropia group (11 students,+0.75D≤SE<- 0.50D) and myopia group (139 students,SE≥-0.5D).According to refractive status,myopia were subdivided into low myopia of 51 cases (-0.5D≤SE≤-3.0D),moderate myopia of 69 cases (-3.0D<SE≤- 6.0D),and high myopia of 19 cases(SE>- 6.0D).Depending on whether there was anisometropia or not,subjects was defined as anisometropic group of 27 cases(spherical degree difference was≥-1.5D,cylinder degree difference was≥-1.0D)and non-anisometropic group of 123 cases(spherical degree difference was<1.5D,cylinder degree difference was<1.0D).Then the different binocular visual functions of the different groups were analysed.RESULTS:The AMP of emmetropia was lower than that of myopia group(t= 1.16,P<0.05).There was difference in the AMP among the three subdivided groups of myopia (F=1.474,P<0.05).The deeper degree of myopia,the higher level of AMP,but only the high myopia had significant difference from the other ones(P<0.05).There was no significant difference in stereopsis between emmetropia and myopia (χ2=0.325,P>0.05).There were no significant differences among low,moderate and high myopia (χ2=0.16,P>0.05).The anisometropia had an impact on stereopsis,people who had anisometropia had a poor stereopsis,the result was statistically significant(Fisher,P<0.05).CONCLUSION:The AMP of emmetropia is lower than the myopia group.In myopia,the AMP and the degree of myopia is positively correlated.People who have anisometropia have a poor stereopsis.
