Answer

Answer

Occasionally, transient vision loss is familial. Multiple episodes of transient vision loss have been described in children with elicited repetitive stereotyped daily blindness of unknown etiology. This rare condition is associated with childhood epilepsy, hemiplegic migraine, and other epileptic disorders through genetic links such as missense mutations in SCN1A. [12, 13]
