Biometric analysis of pigment dispersion syndrome using anterior segment optical coherence tomography.

Purpose: To compare anterior chamber volume (ACV), iris volume, and iridolenticular contact (ILC) area before and after laser peripheral iridotomy (LPI) in eyes with pigment dispersion syndrome (PDS) using anterior segment optical coherence tomography (AS OCT) and image processing software.

Design: Cross-sectional study.

Participants: Eighteen eyes of 18 patients with PDS; 30 eyes of 30 controls matched for age, gender, and refraction.

Structure-function relationships using spectral-domain optical coherence tomography: comparison with scanning laser polarimetry.

Purpose: To evaluate and compare the regional relationships between visual field sensitivity and retinal nerve fiber layer (RNFL) thickness as measured by spectral-domain optical coherence tomography (OCT) and scanning laser polarimetry.

Design: Prospective cross-sectional study.

Methods: One hundred and twenty eyes of 120 patients (40 with healthy eyes, 40 with suspected glaucoma, and 40 with glaucoma) were tested on Cirrus-OCT, GDx VCC, and standard automated perimetry.
