Brief Summary
Myopia (nearsightedness) is increasing in prevalence throughout the world. It is associated with a risk of potentially blinding complications such as retinal detachment and myopic maculopathy. There is a direct association between the degree of myopia and the risk of complications. Myopia develops in childhood and during adolescence. To prevent higher degrees of myopia, we need to halt disease progression in children and teenagers. Low-dose atropine eye drops have been shown to reduce myopia progression by 50% in Asian populations but its effect in non-Asian populations is unknown. The aim of this study is to investigate if low-dose atropine can reduce myopia progression in Danish children and teenagers. The study is an investigator initiated randomized clinical trial conducted as a collaboration between three Danish Eye Departments covering all of Denmark.

Study Arms (3)
Loading dose
EXPERIMENTALIn phase 1 (treatment phase), the participants (n=33) will receive 0.1% atropine loading dose for 6 months followed by 0.01 % atropine for 18 months. The eye drops are administered as one eye drop daily in each eye at bedtime. In phase 2 (washout phase), treatment will be stopped and the participants monitored for 12 months.
Low dose
EXPERIMENTALIn phase 1 (treatment phase), the participants (n=32) will receive 0.01 % atropine for 24 months. The eye drops are administered as one eye drop daily in each eye at bedtime. In phase 2 (washout phase), treatment will be stopped and the participants monitored for 12 months.
Placebo
PLACEBO COMPARATORIn phase 1 (treatment phase), the participants (n=32) will receive placebo eye drops for 24 months. The eye drops are administered as one eye drop daily in each eye at bedtime. In phase 2 (washout phase), treatment will be stopped and the participants monitored for 12 months.
Interventions
0.1% atropine loading dose for 6 months followed by 0.01% atropine for 18 months
Eligibility Criteria
You may qualify if:
- Children aged ≥6-\<9 years: myopia ≤-1 (spherical power) in at least one eye
- Children aged ≥9-≤12 years: myopia ≤-2 (spherical power) in at least one eye
- Cylinder less than 1.5 diopters
You may not qualify if:

- Collagen syndroms (Ehlers-Danlos syndrome, Marfan syndrome and Stickler syndrome)
- Other ocular pathology (e.g., amblyopia, strabismus)
- Previous eye surgery
- Previous use of agents thought to affect myopia progression, e.g. atropine, pirenzepine or 7-methylxanthine (metabolite of caffeine and theobromine) and orthokeratology contact lenses
- Known allergy to atropine or any of the contents of the trial medication (active and in-active ingredients) used in the study
- Non-compliance to eye examinations
- Serious systemic health troubles (e.g., cardiac or respiratory illness) and developmental disorders and delays
