Purpose: To report a series of patients who presented bilateral retinopathy associated with coronary intervention. Methods: Retrospective review of the medical records of seven patients who developed retinopathy following coronary intervention for acute myocardial infarction. All patients were male and mean age was 66.3 year-old. All patients had a history of acute myocardial infarction treated with percutaneous transluminal coronary angioplasty (PTCA) and stent insertion 2-20 days (mean: 9.7 days) prior to ocular examination. In three patients, intra-aortic balloon pumping (IABP) was performed during coronary intervention. Five patients had type 2 diabetes and three had systemic hypertension on presentation. Serum sugar had been well controlled in two of five diabetic patients prior to myocardial infaction. Results: Bilateral cotton wool spots centered around the peripapillary region following coronary intervention was observed in seven patients. In four out of the seven patients, scattered retinal hemorrhage were also observed in both eyes. These retinal findings were similar to microembolic retinopathy secondary to cardiac surgery involving cardiopulmonary bypass (CPB). The retinopathy after coronary intervention resolved spontaneously in all patients. In three out of five diabetic patients, mild nonproliferative diabetic retinopathy remained. Visual impairment was not observed in all cases. Conclusion: Coronary intervention including PTCA and stent insertion can be a cause of retinopathy. Microembolic retinopathy secondary to surgery involving cardiopulmonary bypass (CPB) is well documented as post-pump retinopathy. Although coronary intervention without CPB is less invasive procedure, it can cause retinopathy (Coronary Intervention Retinopathy) similar to post-pump retinopathy.
