Pupillometry in congenital central hypoventilation
Category: Critical Care
A total of 316 monocular measurements were taken under dark-adapted conditions with a fixed light stimulus from 22 PHOX2B mutation-confirmed cases with CCHS and 68 healthy controls.These reductions are indicative of both sympathetic and parasympathetic deficits in CCHS , which is in...
