Application of compound tropicamide and atropine in mydriatic refractometry for ametropia children

Objective To compare the effect of compound tropicamide and atropine ophthalmic solution in mydriatic refractometry for ametropia children. Methods 126 cases(252 eyes) ametropia children aged from 4 to 18 years w ere randomly selected,using tw o kinds of mydriatic( compound tropicamide and atropine) to dilate the pupils successively. All cases w ere grouped by age as group A( 8 years),group B(8 ~ 12 years) and group C( 12 years).The optometry results w ere measured and compared by paired T-test. Results There w as significant difference in diopter of hypermetropia children in group A and group B( P 0. 05) betw een different mydriatic drugs treatment,w hile no significant difference w as found in group C( P 0. 05). There w as significant difference w as found in group A( P 0. 05) for myopia children,w hile no significant difference w as found in group B and group C( P 0. 05). Conclusion The application of atropine in mydriatic refractometry for myopia children aged below 8 years and hypermetropia children aged below 12 years is necessary.
