Compare And Research Among Different Methods Of Binocular Balance

ObjectiveExplore the best method for binocular balancing to improve the conventional optometry and to help the patients establish an excellent binocular vision after getting a binocular balancing status.MethodsEach of the50patients was examined by six different binocular balancing tests after ordinary optometry. Accommodative lag used for comparing binocular accommodation under fusion was gained by dynamic retinoscopy. Then, the data is analyzed by factorial designed analysis of variance and Dunnett-t with SPSS13.0. Additionally,54patients complete a two-color experiment except the binocular balancing. The data is analyzed by analysis of variance with SPSS13.0. Group the patients by the diopter of myopia and analyze the data by factorial designed analysis of variance with SPSS13.0.Result①The sequence between balance and fog, methods and the interaction effect impacting on the result are statistically significant (F=15.610,P<0.01;F=3.088,P<0.05; F=4.570,P<0.05).②No significant differences only was found between the prism dissociation done before fogging and the control group (P>0.05).③The result is similar to MPMVA using the red-green split visual target (F=22.655,P<0.01)ConclusionThe prism dissociation done before fogging and the red-green split visual target would be relatively the best method.
