Use of Optical Coherence Tomography by Nonexpert Personnel as a Screening Approach for Glaucoma.

ABSTRACT:

Purpose

This pilot study was conducted to assess optical coherence tomography (OCT) as a screening tool for glaucoma when used by nonexpert personnel.

Methods

This prospective case-control study included 54 patients with open-angle glaucoma and 54 age-matched comparison individuals. Optovue iVue SD-OCT imaging was performed by nonprofessional photographers on undilated patients. The sensitivity, specificity, negative predictive value, and positive predictive value of iVue scan parameters for detecting open-angle glaucoma were evaluated.

Results

The iVue cup to disc vertical ratio had a sensitivity of 0.96 [95% confidence interval (CI), 0.90-1.00] at 90% specificity and was strongly correlated with both the Cirrus HD-OCT cup to disc vertical ratio (Pearson coefficient=
