aAL was not included in the standard ophthalmological examination 1 year prior to start of therapy and was not included in the children who stopped atropine treatment.
bAllergies developed after 1 year. First-year data are on treatment, 2nd and 3rd year were without treatment.
cAdverse events included photophobia, reading difficulties, nightmares, and deterioration of behavioral problems in a child with diagnosis of ADHD.
