Retinal electrophysiological results in patients receiving lamotrigine monotherapy.

Purpose: To evaluate the effects on vision in patients receiving lamotrigine (LTG) monotherapy.

Methods: Twenty-four consecutive patients taking LTG for partial seizures were referred for a routine ophthalmologic examination including visual acuity testing, tonometry, slit lamp, and fundus examination. Automated kinetic perimetry, electrooculogram (EOG), and electroretinogram were performed after informed consent was obtained.
