ABSTRACT
Objective To investigate the effect and safety of Atropine preparations of 0.1%and 0.01%concentrations in the treatment of Ametropia.Methods 123 cases of ametropia from April 2014 to August 2015 in ophthalmic hospital of ningbo were randomly selected and divided into three groups, 41 cases in each group.High concentration group received 0.1%atropine sulfate eye drops treatment,low concentration group received 0.01%atropine sulfate eye drops treatment,and the control group received artificial tear mytear,and three groups were treated for one year.Changes in vision, refraction, intraocular pressure and axial length of the eye were compared after the treatment.Results High concentration group >low concentration group >control group in the the difference of distant visual acuity before and after the treatment ( Plow concentration group>high concentration group in the refractive index,intraocular pressure and ocular axis length difference before and after treatment (P<0.05),and the effective rate in the low concentration group 85.37%and high concentration group 90.24%had no significant difference.Adverse effects rate in high concentration group was 21.95%which was higher than low concentration group 4.88%(P<0.05).Conclusion 0.1%and 0.01%concentrations of atropine were effective control of Ametropia in flexion and axial length spectrophotometry, and then improve the visual acuity, and the former is better,but the 0.01%concentrations had higher safety.
