Diagnosis and treatment of accommodative insufficiency and convergence insufficiency in asthenopia

Abstract

Complicated and nonspecific clinical manifestations of asthenopia bring certain difficulties to clinical diagnosis and etiolo gical treatment of it.With the in-depth understanding of the disease,its etiology is very complex and often multifactorial.Therapeutic effect is not ideal if only symptomatic treatment was delivered.Exploring the causes of the disase and treating them is the basic therapeutic strategy.It has become clear that many factors can lead to asthenopia.Some necessary ophthalmologic and optometry examinations can ensure etiological diagnosis.Different etiological treatments for asthenopia are with different difficulties.Only simply removal or correction of some causes can avoid symptoms,while others are relatively difficult,such as accommodation and convergence.On the other hand,the poor popularity of the examination of accommodation and convergence makes it difficult to find their effect on asthenopia and to treat them.We summarized the status quo of the diagnosis and therapy of accommodative insufficiency and convergence insufficiency in asthenopia,in order to contribute to the clinical work.
