A 60-year-old female patient receiving epidural buprenorphine for post
operative analgesia developed intractable nausea and vomiting not resp
onding to antiemetics. Ophthalmic consultation for congestion of the l
eft eye was sought and the patient was diagnosed as having phakomorphi
c glaucoma. Extracapsular extraction of the left lens was performed af
ter primary anti-oedema measures. Glaucoma as a cause of intractable p
ostoperative nausea and vomiting should be considered in susceptible p
atients.
