Study on Contrast of Computer Optometry After Dispersing Pupil by Mydrin-p and Atropine in Clildren with Myopie

【Objective】To explore the practical value of Mydrin-p in children with myopia.【Methods】Fifty four children with myopia were under the age of 12.First,Mydrin-p was used to disperse pupil,and optometry by computer with TOPCON MR-8800 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,but no difference in the mean of column lens and that of axis after mydriasis.【Conclusion】Mydrin-p can't 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 preventing of amblyopia.
