Changes in choroidal and retinal thickness 6 months before and during 18 months of orthokeratology lens treatment in myopic children

Key Points

• A notable increase in retinal and choroidal thickness occurred during treatment with orthokeratology lenses.
• Choroidal thickness changes were not found predictive of overall eye length growth over time.
• Observational analysis over 18 months assessed the impact of orthokeratology on myopic children's eye structure.
• Further studies are needed to fully understand the structural changes brought about by orthokeratology lenses.
