Vigabatrin, but not Gabapentin or Topiramate, Produces Concentration‐related Effects on Enzymes and Intermediates of the GABA Shunt in Rat Brain and Retina

Abstract

These findings corroborate a previously reported accumulation of VGB in the retina, which may be responsible for the visual field constriction observed clinically. This phenomenon does not appear to extend to other GABAergic drugs, suggesting that these agents might not cause visual field defects.
