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.

Partially reversible quadruple sectoranopia caused by vascular steal due to an arteriovenous malformation.

Background: Lateral, homonymous upper and lower field blind sectors sparing a horizontal zone define quadruple sectoranopia. This rare campimetric deficit involves ischemia or infarction of parts of the lateral geniculate body supplied by the distal anterior choroidal artery.

Methods: A 41-year-old patient presented with a complaint of blurred vision.

The effect on vision of associated treatments in patients taking vigabatrin: carbamazepine versus valproate.

Purpose: To evaluate the effect on visual function of a concomitant antiepileptic drug (AED) in patients treated with vigabatrin (VGB).

Methods: Sixty-four consecutive patients with a history of partial seizures currently treated with VGB with either carbamazepine (CBZ) or valproate (VPA) were examined with automated kinetic perimetry, static perimetry, electrooculogram (EOG), and electroretinogram (ERG). An original device based on kinetic perimetry was developed to quantify the area of perception for each isopter.

Resolution of acute acquired comitant esotropia after suboccipital decompression for Chiari I malformation.

Purpose: To report a case of acute comitant esotropia successfully treated with suboccipital decompression in a 9-year-old male patient with Chiari I malformation.

Design: Interventional case report.

Methods: A 9-year-old male with Chiari I malformation had acute onset of diplopia, headache, and comitant esotropia.
