Abstract
Cortical blindness is characterized by unilateral or bilateral vision loss despite an intact pupillary reflex, full extraocular movements, and normal fundoscopic examination. Common causes include stroke, cardiac emboli, head trauma or rarely, a hypoxic-ischemic event which results to decreased perfusion to the occipital lobes supplied by the posterior cerebral artery. Imaging with computed tomography is usually diagnostic documenting stroke or embolization as well as ensuring an intact cerebral circulation. Prognosis largely depends on the etiology as most reports document an irreversible condition or at least the patient is left with some residual visual symptoms.
We present a case of a 25-year-old male who underwent brachial artery repair with reverse saphenous vein graft interposition after sustaining a right upper arm laceration associated with massive hemorrhage and shock due to delayed consult. He presented with profound bilateral loss of vision 12 h after surgery characterized as right homonymous hemianopsia. Computed tomography of the brain demonstrated ischemic infarcts in the occipital lobes. Close observation was instituted, and his symptom resolved spontaneously within a week. This case highlights the importance of considering atypical causes of perioperative vision loss as early recognition and timely diagnosis are essential to improve patient outcomes. To our knowledge, this is the first report of transient cortical blindness after peripheral vascular trauma.
期刊介绍:
Trauma Case Reports is the only open access, online journal dedicated to the publication of case reports in all aspects of trauma care and accident surgery. Case reports on all aspects of trauma management, surgical procedures for all tissues, resuscitation, anaesthesia and trauma and tissue healing will be considered for publication by the international editorial team and will be subject to peer review. Bringing together these cases from an international authorship will shed light on surgical problems and help in their effective resolution.
