Effects of atropine and compound tropicamide on mydriatic refractometry in juvenile with ametropia

Objective To study the effect of atropine and compound tropicamide in mydriatic refractometry of juvenile with ametropia. Methods Forty patients with ametropia were divided into two groups by age(GroupⅠ,5-10 years old,n=40;GroupⅡ,11-20 years old,n=40).All eyes were examined by mydriatic refractometry after 1% atropine and compound tropicamide. Results There was a statistical difference in mydriatic refractometry between 1% atropine and compound tropicamide in group Ⅰ,but not in group Ⅱ. Conclusion Mydriatic refractometry using atropine is more accuract for the young patients with ametropia from 5 to 10 years old,but not necessary for the young patients with ametropia from 11 to 20 years old.
