ARTICLE HIGHLIGHTS
Research background

Coronary artery bypass grafting (CABG) is currently used in most patients with coronary artery diseases. One of the unfavorable reported events following CABG is postoperative vision loss.

Research motivation

Ocular structures are vulnerable to hemodynamic changes, which are expected during and after CABG. Changes in choroidal and retinal structures can be the cause of this complication.

Research objectives

To assess the changes in choroidal and retinal structures after CABG.

Research methods

A total of 49 eyes in 25 candidates for CABG underwent comprehensive ophthalmic and cardiovascular examination before and after surgery.

Research results

A decrease in visual acuity was detected, while changes in choroidal and retinal structures were not significant.

Research conclusions

CABG may lead to visual acuity reduction without affecting the ocular structures. The possibility of cellular or central nervous system damage should be considered.

Research perspectives

Larger studies with further evaluation such as optical coherence tomography angiography are required in this regard.
