She says that, several hours ago, her vision began to get dim, and she sees halos around light sources. This was immediately followed by a severe frontal headache. Past medical history is significant for epilepsy. The patient says her anticonvulsant medication was changed recently but she doesnt remember the name. Slit-lamp examination reveals mild chemosis, injection, and ciliary flush with diffuse stromal haze, along with very shallow peripheral anterior chambers with areas of iridocorneal touch in both eyes. Gonioscopy showed closed angles bilaterally. Which of the following antiepileptic drugs is most likely responsible for this patients condition?? A: Lamotrigine, B: Topiramate, C: Gabapentin, D: Zonisamide, E: Tiagabine,  <response>: This is a clinical case scenario describing a 34-year-old woman who presents with acute vision loss and visual disturbances. She has a history of epilepsy and was recently started on a new anticonvulsant medication. The ocular exam findings of shallow anterior chambers, closed angles on gonioscopy, and symptoms of headache and halos around lights are consistent with acute angle closure glaucoma. The question asks which anticonvulsant medication is most likely responsible for causing this condition. Some anticonvulsants like topiramate and zonisamide are associated with secondary angle closure glaucoma due to ciliochoroidal effusion. Others like gabapentin and tiagabine do not have this adverse effect. Lamotrigine is also not typically implicated in drug-induced angle closure glaucoma.B: Topiramate
