Clinical value of compound tropicamide in children with refraction error

Objective To explore the practical value of compound tropicamide in children with refraction error.Methods 40 children(80 eyes) with refraction error were divided into two groups according to the age,one group of 4-12 years old and the other group of 12-16 years old.Compound tropicamide was used to disperse pupil.And optometry was performed by computer with T0PC0N MR-8800 unit.After that,atropine gutta was applied three times daily for three days.And optometry was conducted by the same computer.The changes of diopter were analyzed and compared.Results In the group of 4-12 years old children,there was significant difference between Mydrin and atropine gutta in means of the spherical lens(P0.05),but no difference in the mean of column lens or axis after Compound Tropicamide(P0.05).Conclusion Mydrin can not replace atropine in optometry under the age of 12,but it can play an active role in the test of astigmatism and prevention of amblyopia.
