ACHOO syndrome is an autosomal dominant (OMIM:100820) condition affecting ± 25% of the general population, characterised by paroxysms of sneezing when passing from dark to bright light or direct sunlight (the so-called helicociliosternutatogenic reflex) or in response to periocular injections. Two-thirds of photic sneezers are female, 94% are white.
At least one study suggests that it is acquired rather than inherited.
