“…Palinopsia is usually accompanied by a visual field defect but some cases with a normal visual field have been observed such as that described by Praveen-Kumar and Rajesh ( 10 ), a patient affected by a temporo-occipital anaplastic oligodendrioglioma, or those of Ritsema et al ( 11 ), one with an arteriovenous malformation in the lingual gyrus of the left occipital lobe and one with an ischemic stroke in the left peri-atrial region, near to the left optic radiations. In addition, multiple illicit drugs (marijuana, mescaline, lysergic acid dyethilamide, 3,4-methylenedioxymethamphetamine), and prescription drugs (interleukin 2, topiramate, trazodone, clomiphene citrate, nefazodone) can elicit episodes of palinopsia ( 12 – 14 ). Other known causes include poisoning with carbon monoxide or different other gazes, psychiatric conditions (Charles-Bonnet syndrome, schizophrenia, psychotic depression), metabolic and systemic diseases (non-ketotic hyperglycemia, diffuse cortical pathology), migraine, or diseases limited to the retina or optic nerve ( 3 , 5 ).…”
