NCT03949101

Brief Summary

Investigators are going to conduct a randomized controlled trial that myopic children are randomly allocated into two groups: combined use of 1% atropine and 0.01% atropine (experimental group) and 0.01% atropine (control group) in order to explore a better way to control myopia progression and eliminate adverse effects at the same time, provide reliably evidence for clinical guideline of atropine use in children, and investigate the mechanism of atropine on eyes.

Study Arms (2)

combined use of 1% atropine and 0.01% atropine

EXPERIMENTAL

first week, use atropine sulfate 1% ophthalmic ointment every night before sleep; then use atropine sulfate 1% ophthalmic ointment once every week(Friday night before sleep is recommended) for half a year; then use atropine sulfate 0.01% eye drop every night before sleep for one year and a half.

Drug: Atropine Sulfate 1 % Ophthalmic Ointment and Atropine Sulfate 0.01% Eye Drop

0.01% atropine

ACTIVE COMPARATOR

use atropine sulfate 0.01% eye drop every night before sleep for two years.

Drug: atropine 0.01% eye drop

Interventions

use one drop into subconjunctiva

combined use of 1% atropine and 0.01% atropine

use one drop into subconjunctiva

0.01% atropine
