Low-dose Atropine for the Prevention of Myopia Progression in Danish Children (APP)
Low-dose Atropine for the Prevention of Myopia Progression in Danish Children - a Randomized, Double-masked, Multicenter, 36-month Prospective 1:1:1 Study of Safety and Efficacy of 0.1% Atropine Loading Dose to Single 0.01% Atropine and Placebo

Detailed Description
The main hypotheses tested in this study are:
- 0.01% atropine one drop nightly reduces the progression of childhood myopia in Danish children.
- 0.01% atropine one drop nightly is safe and with no significant side effects.
- A 6-month loading dose of 0.1% atropine followed by a 0.01% atropine maintenance dose is superior to single 0.01% atropine.
- 0.1% atropine one drop nightly is safe and has tolerable side effects.
- The rebound effect after stopping both atropine regimens is limited.
- Choroidal thickness is a predictor for the progression of childhood myopia.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Loading dose
In phase 1 (treatment phase), the participants (n=50) 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. |

Experimental: Low dose
In phase 1 (treatment phase), the participants (n=50) 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 Comparator: Placebo
In phase 1 (treatment phase), the participants (n=50) 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. |
