Objective Compare the effectiveness of three treatment methods,namely the “convergence and accommodation training",the “correction of weared prism" and the “overcorrection of Myopic refractive" in patients with convergence insufficient exophoria accompanying with accommodative insufficiency.Methods It was a cross-sectional study.Sixty patients between 10 and 35 years' old who are diagnosed with convergence insufficient exophoria accompanying with accommodative insufficiency were randomly divided into three groups with 20 cases in each group.Patients in group A were corrected by weared prism,patients in group B were trated by the overcorrection of Myopic refractive (-0.50 D spectacles correction),patients in group C were treaded by convergence and accommodation visual function raining.Their phoria and visual functions were reviewed after three months.Results There are significant differences among the function parameters of the three groups of patients after review their visuals in three months' time.The heterophoria diopter increased in group A patients (t=12.65、P<0.01).The range of near-distance positive relative convergence has reduced (t=12.65,P<0.01),after a short reduce,the symptoms of the patients in this group have increased.The heterophoria diopter of the patients in Group B has increased (t=4.63,P<0.01).The range of near-distance positive relative convergence has reduced (t=6.71,P<0.01).The accommodative amplitude decreased (t=14.3,P<0.01) and the symptoms got worse significantly.However,the heterophoria diopter has significantly reduced in patients of group C (t=-1 1.61,P<0.01).Their range of near-distance positive relative convergence has significantly increased (t=-22.40,P<0.01),the accommodative amplitude (t=-31.06,P<0.01) has increased significantly as well.Thesymptoms were improved significantly.Conclusion After the treatment of the convergence and accommodation visual function raining,the symptoms of the patients diagnosed with convergence insufficient exophoriaaccompanying with accommodative insufficiency were improved significantly,their heterophoria dioptcr has reduced,and the range of near-distance positive relative convergence and the accommodative amplitude has increased.In summary,this treatment is a feasible and effective treatment.
