What are the risks associated with orbital decompressive surgery?

Serious complications from decompressive surgery e.g. loss of vision, are extremely rare. The major potential complication which must be considered is postoperative bleeding and double vision. Significant postoperative bleeding is very rare and can easily managed if recognized early enough. Thus we do advice our patients for an inpatient procedure with close-up monitoring during the first 24 hours after surgery. The incidence of postoperative double vision varies considerably from centre to centre. It is much more of a problem in patients who have some double vision prior to surgery with a risk of up to 30% that this may be worse postoperatively. In patients with no pre-existing double vision, the risk is considerably reduced (<5%). It is rare for any patients who suffer this complication to be left with a significant problem following corrective eye muscle surgery. This risk must, however, be considered very carefully in a patient who wishes to improve cosmesis as this has implications for driving. It may be necessary to wait for some months before muscle surgery can be undertaken to improve double vision. In some patients temporary prisms can be fitted to glasses to improve double vision.
Other potential complications which should be considered:
  • Infection
  • Loss of sensation in the cheek, side of the nose and front teeth
  • Retraction of the lower and/or upper eyelid
