“…2,3 Most authors agree that a patient-based approach should be used to determine which patients would be most likely to benefit from each procedure: high-risk patients, patients with a history of cerebral stroke, vascular disease, kidney failure, and liver disease are some of the patients in which OPCAB has been deemed advantageous. 4,5 Hemodynamic changes and the systemic inflammatory response after on-pump surgery have been postulated to cause changes in retinal and choroidal circulation. 6,7 Purtscher-like retinopathy is a prominent example of the effect of onpump CABG-related inflammatory response on the retina.…”

Background: Cardiac surgery has been associated with adverse ocular events. Off-pump coronary artery bypass graft surgery evades the systemic inflammatory response seen in extracorporeal circulation and is superior to on-pump surgery with regard to end-organ dysfunction and neurological outcomes. Objectives: To determine the effects of off-pump (without extracorporeal circulation) coronary artery bypass graft surgery on choroidal thickness, ganglion cell complex, and the retinal nerve fiber layer. Design: Prospective, longitudinal study. Methods: Patients who underwent off-pump surgery were examined preoperatively and postoperatively at 1 week and 6 weeks after surgery. Choroidal thickness, ganglion cell complex, and the retinal nerve fiber layer measurements were recorded, and the effects of off-pump coronary artery bypass on these parameters were assessed. Results: A total of 44 eyes of 44 patients were included in the study. There was a statistically significant increase in subfoveal choroidal thickness from 252.84 ± 56.24 µm preoperatively to 273.82 ± 39.76 µm at 1 week and 301.97 ± 44.83 µm at 6 weeks after off-pump coronary artery bypass graft surgery ( p = 0.044; p ⩽ 0.001). Ganglion cell complex and retinal nerve fiber measurements showed no significant difference compared to preoperative values. Conclusion: Off-pump coronary artery bypass graft surgery showed no negative effects on ganglion cell complex and retinal nerve fiber measurements. A significant increase in subfoveal choroidal thickness was seen after off-pump surgery, which might be advantageous in patients who are at high risk or have preexisting ocular diseases that are affected by the choroid.
