Analysis on the clinical efficay of Xin Liu Ding(Raceanisodamine) Eye Drops on incipient juvenile myopia

Objective:To evaluate the clinical efficacy of Xin Liu Ding(Raceanisodamine) Eye Drops on incipient juvenile myopia.Methods:Thirty younger subjects(60 eyes) with incipient myopia aging from 10-15 years old were followed up.Xin Liu Ding was given to all the subjects.The alteration in uncorrected visual acuity,spherical equivalent,intraocular pressure and axial length were tested and adverse reactions were recorded at 1 month,3 months,and 6 months after drug administration.Results:The average uncorrected visual acuity of the younger subjects was 0.34±0.19,and was markedly elevated to 0.52±0.21 at 1 month after drug therapy.The difference was significant(P 0.001).The spherical equivalent values decreased correspondingly(P 0.001).It was continuously improved at 3 months after drug therapy(P 0.05).But the spherical equivalent at 6 months had no difference with that at 3 months(P 0.05).The intraocular pressure had no significant difference before and after drug administration.The axial length increased by 0.11 mm averagely at 6 months.No adverse reaction was observed.Conclusion:Xin Liu Ding Eye Drops may control the incipient juvenile myopia properly and has no significant adverse reactions.
