What is Choroidal Thickness in Young Adults and Its Association with Visual Acuity about?

## Purpose: To describe the choroidal thickness (cht) in a large sample of young adults with the aim of establishing a normative cht profile reference in this demographic cohort and explore its association with best-corrected visual acuity (bcva). ## Design: Cross-sectional study. ## Methods: From a single center, 741 young adults (19-30 years of age, 49% male) were recruited to undergo a comprehensive ophthalmic examination, including bcva measurement, post-cycloplegic autorefraction, ocular biometry, tonometry, and spectral-domain optical coherence tomography (sd-oct) imaging. the enhanced depth imaging mode on the sd-oct was used. the main outcome measure was the central macular cht (0.5-mm radius around the fovea). the chts at the inner (between 0.5-mm and 1.5-mm radius) and outer macular rings (between 1.5-mm and 2.5-mm radius) were also measured. ## Results: The median central macular cht was 370 μm (interquartile range 312-406 μm). the choroid was thickest at the superior-inner, inferior-inner, and central macular regions (370-373 μm) and thinnest nasally at the outer macular region (median 256 μm). decreased central macular cht was associated with younger age, female sex, n
