Objective To observe the pathogenesis and therapy of asthenopia.Methods It was a prospective case series study.One hundred and three patients with asthenopia were included.The function of accommodation and fusion test including distance and near phoria,horizontal convergence and divergence,near point,accommodative convergence/accommodation ratio,amplitude of accommodation,accommodative facility,relative accommodation,accommodative response was examed,and the pathogenesis was analyzed.Therapies include correct ametropia,vision training,prism correction,pharmacologic treatment.The symptom of asthenopia before and after treatment was evaluated with a qucstionnaire,and compared with a paired t test.Results The sex ratio of the 103 patients with asthenopia was 1:1.5 (male:female)、There were 38 cases of ametropia (36.9%),26 cases of dry eye (25.2%),29 cases with convergence or divergence problems (28.2%),and 10 cases with accommodation problems (9.7%).The symptom of asthenopia score was 4.8±0.7 before treatment,after treatment,all cases showed improvement in asthenopic symptoms,and the symptom of asthenopia score was 2.0±0.6,compare with before treatment,the difference was significant (t=16.0,P<0.01 ).Conclusion Most of the patients with asthenopia had identifiable pathologies or deficits.The pathogenic causes of asthenopia are ametropia,dry eye,accommodation abnormalities,and convergence or divergence abnormalities.The therapy for correction of ametropia is training,prism,medication,etc.
