Phakomorphic glaucoma--an unusual cause of postoperative vomiting.

A 60-year-old female patient receiving epidural buprenorphine for postoperative analgesia developed intractable nausea and vomiting not responding to antiemetics. Ophthalmic consultation for congestion of the left eye was sought and the patient was diagnosed as having phakomorphic glaucoma. Extracapsular extraction of the left lens was performed after primary anti-oedema measures. Glaucoma as a cause of intractable postoperative nausea and vomiting should be considered in susceptible patients.
