   A Case Report
   Robert E. Windsor, MD, and Samuel Thampi, MD.

This case report is of a 46-year-old patient who developed blurred vision shortly following an opiate pump (Drug AdministrationSystem, DAS) placement for chronic pain  due to chronic lumbar radiculopathy and a multiply operated spine. Following the implant she complained of positional headaches and blurred vision. The headache gradually subsided with rehydration. However, one week after the pump placement she continued to complain of blurred vision and diplopia. Neurologic examination revealed left lateral rectus palsy. A neurologist was consulted who confirmed the diagnosis. The symptoms gradually abated.
