简要总结

STUDY OBJECTIVE   : To evaluate the efficacy and safety of low strength         atropine eyedrops 0.01% in treatment of progressive myopia in children and young adults

CLINICAL HYPOTHESIS   :    Low dose atropine (0.01%) eyedrops is effective in preventing or slowing down the progression of myopia in children as well as young adults, with minimal or insignificant side effects.

Single centre, Randomised Controlled Trial ; Parallel arm, Interventional design

The primary outcome will be progression of myopia estimated as the change in spherical equivalent refractive error relative to the baseline. The secondary outcome will be the change in axial length with respect to the baseline measurement.

The ATOM studies established the effect of Atropine in preventing the progression of low to moderate myopia and it was concluded that at low strength of 0.01% the drug showed optimum efficacy with minimal side effects and minimal rebound.

However the study failed to study high myopes (>6 D) and children above 12 years while myopic progression can continue in young adults.

Also the study duration was limited which fails to bring out the persistence of the long term results.

So we designed this study to study the efficacy of low strength Atropine(0.01%) in the Indian population, to assess its efficacy in high myopia and to assess the persistence of the efficacy as well as the safety profile for a longer period. Also we intended to include a higher age group ie upto 15 years (Inclusion age: 5-15 years) which was not included in the ATOM studies.
