Research of near stereopsis in clinical treated amblyopes / 安徽医科大学学报

ABSTRACT

104 successful treated amblyopes were screened from the ophthalmology outpatient departmt,who had successfully amblyopia treatment,all with the corrective visual acuity around 0.8 and the visual acuity of two eyes were less than two lines.Titmus stereogram was used to test stereoacuity,the chi-square test was used to analyze the results.There was statistical significance between the three types of amblyopia(x2 =11.294,P ＜ 0.05),individuals with ametropic amblyopia have better stereoacuity than others,individuals with anisometropic amblyopia and strabismic amblyopia have worse stereoacuity than others;There was statistical significance between different degrees of amblyopia (x2 =13.455,P ＜ 0.05),individuals with mild and moderate amblyopia have better stereoacuity than others,individuals with severe amblyopia have worse stereoacuity than others;There was statistical significance between differentdiagnosed age (x2 =11.263,P ＜ 0.05),the first diagnosed age less than 7 years old was better than over 7 years old;No difference was identified between thestereoacuity of monocular and binocular amblyopia.The visual acuity of different kinds of amblyopia could recover to normal level after regular amblyopia treatment,however,the stereoacuity has not recovered to normal level,it is necessary to take exercise to improve binocular function.As a result,the stereoacuity is considered to be a standard to evaluate the effect of amblyopia treatment.
