Quantitative Comparison of Fundus Images by 2 Ultra-Widefield Fundus Cameras.

ABSTRACT:

Purpose

To compare the relative number of retinal pixels and retinal area imaged using the Optos P200DTx (Optos PLC) and Zeiss Clarus 500 (Carl Zeiss Meditec AG) ultra-widefield (UWF) fundus cameras.

Design

Single-center retrospective cross-sectional analysis.

Participants

Seventy-eight eyes of 46 patients.

Methods

Eyes were imaged with Optos P200DTx, single-capture, and Zeiss Clarus 500, 2 capture montages when possible, UWF fundus cameras. Relative number of pixels encompassing all foveal-centered retinal quadrants were measured. Retinal area was measured with Zeiss Clarus 500 images that were registered to the Optos P200DTx images. Patients and technicians were asked for preferences between the machines. Imaging session times were recorded.
