Choroidal volume variations with age, axial length, and sex in healthy subjects: a three-dimensional analysis.

ABSTRACT:

Purpose

To demonstrate the 3-dimensional choroidal volume distribution in healthy subjects using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT) and to evaluate its association with age, sex, and axial length.

Design

Retrospective case series.

Participants

A total of 176 eyes from 114 subjects with no retinal or choroidal disease.

Methods

The EDI SD-OCT imaging studies of healthy patients who had undergone a 31-raster scanning protocol on a commercial SD-OCT device were reviewed. Manual segmentation of the choroid was performed by 2 retinal specialists. A macular choroidal volume map and 3-dimensional topography were automatically created by the built-in software of the device. Mean choroidal volume was calculated for each Ear
