Neurological Literature of Neuro-Ophthalmological Significance

One study suggests establishing zebrafish as a pharmacologic animal model for treating infantile nystagmus, in showing that gabapentin/ memantine significantly reduced nystagmus intensity (1). Implantation of a magnetic oculomotor prosthesis can help patients with acquired disabiliting nystagmus as suggested in a case report in a patient with longstanding upbeat nystagmus due to paraneoplastic syndrome (2). Amantadine as an alternative treatment for periodic alternating nystagmus is suggested by the report of successful treatment in a patient with PAN refractory to baclofen and intolerance to memantine (3).
