Transient smartphone blindness: Relevance to misdiagnosis in neurologic practice

Transient smartphone blindness (TSB) was recently described in 2 women who experienced recurrent episodes of monocular vision impairment immediately after viewing a smartphone.1 This physiologic phenomenon is caused by temporarily discrepant light adaptation levels between the 2 retinae. We confirm the phenomenon of TSB and its relevance to neurologic practice, including the potential for misdiagnosis as cerebrovascular disease or multiple sclerosis (MS).
