Vision loss after non-ophtalmic surgery is rare but destructive complication, which should be informed to the patient preoperatively.

  • A rare case of 59 year-old male patient who underwent double coronary bypass and successfully weaned from it but lost his vision within a week was reported in this.
  • Visual loss is a rare (0.0008% – 0.002%) and destructive complication for patients undergoing bypass surgery, as per the earlier literature.
  • The present patient was admitted for coronary artery disease, presented loss of senses and unstable angina. CABG was performed and the patient had returned to normal sinus rhythm.
  • Then after, on the afternoon of the fourth day, the patient complained for blindness on the left eye and six hours later had suffered complete visual loss.

  • Oedema and discoloration of the papilla bilateral.
  • Treated with methylprednisolone but could not retrieve the clinical status.
  • VA counting fingers 5 meters OD.
