Smartphone-enabled retinal arteriovenous imaging and correlation with coronary SYNTAX score.

ABSTRACT:

Objective

To assess the feasibility of measurement of retinal arteriovenous (AV) ratio using a smartphone, we performed a comparative evaluation with fundus camera imaging and coronary SYNTAX score.

Method

Successive coronary artery disease (CAD) patients who underwent coronary angiography were recruited for smartphone retinal imaging. Following pupillary dilatation, fundus camera images and smartphone photography were performed. Video images were captured with a smartphone, edited and analysed. Retinal artery and vein size at 0.5 and 1 disc diameter (DD) were measured using DICOM software by two independent observers. Another observer calculated SYNTAX score.

Results

Analysable smartphone images were available in 91 (89.2%) of 102 patients. Tobacco use was found in 2
