Importance: Additional data are required regarding atropine treatment regimens for control of myopia progression.
Objective: To investigate the efficacy and safety of different atropine regimens for myopia in children.
Design, Setting, And Participants: This was a secondary analysis of the 3-year results of the 24-Month Myopia Outcome Study of Atropine in Children (MOSAIC) trial, called the MOSAIC2 trial.
Purpose: To investigate 2-year changes in macular choroidal thickness (ChT) in children receiving 0.01% atropine eyedrops and its relationship with spherical equivalent refraction (SER) progression and axial length (AL) elongation.
Methods: A total of 250 myopic children aged 6-16 years (167%-0.
Background/objectives: Axial length, a key measurement in myopia management, is not accessible in many settings. We aimed to develop and assess machine learning models to estimate the axial length of young myopic eyes.
Subjects/methods: Linear regression, symbolic regression, gradient boosting and multilayer perceptron models were developed using age, sex, cycloplegic spherical equivalent refraction (SER) and corneal curvature.
