Comparative study between Mydrin-p and atropine gutta in mydriasis and optometry in children with refraction error

Objective To explore the practical value of Mydrin-P in children with refraction error.Methods 158 children with refraction error were divided into two groups according to ages.First,Mydrin-P was used to disperse pupil,and optometry by computer with TOPCON-8100 unit was performed.After that,atropine gutta(1%) was applied three times daily for three days in succession,then optometry was conducted by the same computer.The changes of diopter were analyzed and compared.Results There was significant difference between Mydrin-P and atropine gutta in means of the spherical lens(P0.05) ,but no difference in the mean of column lens and that of axis after mydriasis(P0.05).Conclusion Mydrin-P can not replace atropine in optometry during children under the age of 12,but it can play an energetic role in the test of astigmatism,screening and prevention of amblyopia.
