Progressive Myopia Clinical Trial
Official title:
Investigator Led, Double-masked, Multicenter, Randomized Clinical Trial for the Comparison of Atropine 0.5% Versus Atropine 0.05% Eye Drops for the Prevention of Myopia Progression in Dutch Children
The goal of this interventional study is to compare the efficacy of Atropine 0.05% to Atropine 0.5% treatment against progression of axial length in European children with progressive myopia, and to evaluate the safety, adherence, and reasons for nonresponse. Subjects will use Atropine eye drops for a period of 3 years, followed by a 2 year observational period.
With the current worldwide myopia boom the frequency of high myopia will also increase, and potentially blinding complications such as myopic macular degeneration, retinal detachment, and glaucoma will occur more often. In the Netherlands high myopia will become the most important cause of low vision and blindness by 2050. As treatment options are limited once the eye is fully grown, prevention of a long axial length at childhood is the only way to counteract this prospect. Pharmacological interventions have shown a high efficacy in stopping eye growth, in particular eye drops with high dose Atropine (0.5%, 1%). Nevertheless, the high frequency of side effects (photophobia, reading problems) of these Atropine concentrations has favoured the use of low dose Atropine. Atropine 0.01% is the most commonly used and lowest dosage; it has shown stability of refractive error, but not of axial length. Recent studies have shown that Atropine 0.05% has low risk of side effects, but a higher efficacy than 0.01%. Many ongoing trials are now comparing various low dose Atropine to placebo, but none are comparing the highest low dose to the lowest high dose Atropine. ;
