Key Points

This research aims to investigate the short-term effects of orthokeratology treatment zone decentration on choroidal thickness and vasculature.
Conducted an observational study over a 1-month period
Measured choroidal thickness before and after orthokeratology treatment
Assessed changes in vasculature during the treatment phase
Choroidal thickening was observed after 1 month of orthokeratology treatment
Treatment zone decentration correlated with alterations in choroidal characteristics

Abstract

Orthokeratology treatment zone decentration is associated with choroidal thickening during 1-month orthokeratology treatment. This early change may provide a new perspective for evaluating its potential role in long-term myopia control.
