In a prospective study of neurological complications of coronary bypass surgery, detailed pre‐ and post‐operative bedside ophthalmological evaluation was undertaken in 312 patients. Post‐operative neuro‐ophthalmological complications developed in 80/312 (25.6%) patients and included: areas of retinal infarction (17.3%); retinal emboli (2.6%); visual field defects (2.6%); reduction of visual acuity (4.5%) and Horner's syndrome (1.3%). Neuro‐ophthalmological complications were not observed in a control group of 50 patients undergoing major peripheral vascular surgery. Ten of 75 patients reviewed at 6 months still had detectable neuro‐ophthalmological abnormalities, but functional disability occurred only in those with persistent visual field defects. Multivariate analysis revealed that extra‐coronary vascular disease, severe and prolonged duration of heart disease prior to operation, and large drop in haemoglobin level during surgery may predispose to neuro‐ophthalmological complications.
