ABSTRACT
In a questionnaire, four of 20 (20%) neurologists indicated they had a photic sneeze reflex. Two kindreds are presented that demonstrate the reflex is inherited in an autosomal dominant mode, but with variable expressivity manifested by sneezing after eyebrow plucking and/or hair pulling. The reflex may result from stimulation of the trigeminal nerve.
