Objective To investigate the effect of type of amblyopia and initial treatment of the age on near stereopsis.Methods Overall 121 cases with ametropic amblyopia of age 3to 9children(after 6months treatment of amblyopia)were observed.The Yan stereogram was used to evaluate near stereopsis function.We observed the effects of different degree of amblyopia and different types of ametropia on near stereopsis functions before and after the operations and the effects of different treatment age on the development of stereopsis.Results Children with ametropic amblyopia had different degrees of near stereopsis,with normal stereopsis 22.92%.Mostly was childen with astigmatic refractive error,and the near stereopsis functions of high hyperopia groups were poor.The earlier the treatment age,the better recovery effects of near stereoscopic functions.The therapeutic effects between different age groups had statistical significance.Six months after the treatment,there also were differences in near stereopsis functions of different degrees of amblyopia groups.Mild and moderate amblyopia groups had better stereopsis functions,and the stereopsis functions were poor in severe amblyopia groups.The difference between the three groups was statistically significant.Conclusion hyperopia has larger influence in visual functions.The earlier the treatment started,the better the stereopsis developed.The latter age of treatment,the poorer recovery the stereopsis and the visual functions.The near stereopsis functions in Astigmatism types were significantly better than those in the hyperopia groups(excluding anisometropia cases),and severe amblyopia has not yet developed in stereopsis later in the treatment although the visual acuity improved.The recovery of binocular vision should be paid more attention during the treatment of amblyopia.
