Abstract | BACKGROUND AND OBJECTIVES: Visual loss is an uncommon complication in the postoperative period of non-ocular procedures and its incidence may be confirmed by the increasing number of studies in the international literature. This report aimed at describing a case of anopsia after prone spinal procedure. CASE REPORT: CONCLUSIONS: This case evidences the possibility of visual loss after prone spine surgery. Ischemic optic neuropathy results from the unbalance between optic nerve oxygen supply and demand as a consequence of increased intraocular pressure (IOP) as compared to systemic blood pressure, determining poor nervous tissue perfusion. Although the cause of this complication is still not explained, risk factors may be advanced age, atherosclerosis, diabetes mellitus, hypertension, smoking, changes in vascular supply and procedure duration.
