Brief Summary:
Patients with partial seizures currently taking 1-3 antiepileptic medications will have a 50:50 chance to receive Lyrica 300 mg per day or placebo (no active ingredients) added on to their current medications for 3 months. Neither the study doctor nor the patient will know the medication assignment. Vision testing will be performed prior to receiving the study treatment and at the end of the study to see if there are any changes.
