Ability of cirrus HD-OCT optic nerve head parameters to discriminate normal from glaucomatous eyes.

ABSTRACT:

Purpose

To determine the ability of optic nerve head (ONH) parameters measured with spectral domain Cirrus HD-OCT (Carl Zeiss Meditec, Inc., Dublin, CA) to discriminate between normal and glaucomatous eyes and to compare them with the discriminating ability of peripapillary retinal nerve fiber layer (RNFL) thickness measurements performed with Cirrus HD-OCT.

Design

Evaluation of diagnostic test or technology.

Participants

Seventy-three subjects with glaucoma and 146 age-matched normal subjects.

Methods

Peripapillary ONH parameters and RNFL thickness were measured in 1 randomly selected eye of each participant within a 200 × 200 pixel A-scan acquired with Cirrus HD-OCT centered on the ONH.

Main outcome measures

Optic nerve head topographic parameters, per
