Choroidal thickness measured by spectral domain optical coherence tomography: factors affecting thickness in glaucoma patients.

ABSTRACT:

Purpose

To measure choroidal thickness and to determine parameters associated with it.

Design

Cross-sectional study.

Participants

Seventy-four glaucoma patients and glaucoma suspects.

Methods

Spectral domain optical coherence tomography (SD-OCT) scans were obtained to estimate average choroidal thickness in a group of glaucoma suspects and glaucoma patients. The average thickness was calculated from enhanced depth SD-OCT images and manually analyzed with Image J software. Open-angle glaucoma, open-angle glaucoma suspect, primary angle-closure glaucoma, primary angle closure, and primary angle-closure suspect were defined by published criteria. Glaucoma suspects had normal visual fields bilaterally. Glaucoma was defined by specific criteria for optic disc damage
