Optical coherence tomography in patients exposed to vigabatrin

1 August 2014 | | Retina / Uvea / Vitreous | anti-epileptic drug, drug toxicity, full-field electroretinography, optical coherence tomography, vigabatrin, visual field defect
Vigabatrin is used to treat epilepsy and can lead to increased levels of gamma-aminobutyric acid (GABA) in the brain and in the retina leading to binasal visual field defects. Although not the first line of treatment for adults it is...

Sclerotomy suturing
