Comments: This short communication is about an uncommon cause of keratoconjunctivitis sicca that is often accompanied by usually unilateral (ipsilateral) dry nose with hyperkeratosis and/or crusting. If nasal lesions are present, damage to the preganglionic parasympathetic fibers proximal to the pterygopalatine ganglion is suspected. Treatment with oral pilocarpine drops appears to yield some benefit. Note: this paper does not provide much detail on nasal lesions, but it explains, in the introduction, the neurologic basis of this syndrome.
