High Pain Sensitivity Linked to Dry Eye Disease
– Reported, August 15 2013
(Ivanhoe Newswire) Researchers at the University Medical Center Groningen, the Netherlands, suggest that high pain sensitivity and low pain tolerance is associated with symptoms of dry eye disease.
Out of the 1,635 female twin volunteers, ages 20 to 83 years from the TwinsUK adult registry, 438 (27 percent) were categorized to have dry eye disease. Qualitative sensory testing using heat stimulus on the forearm was used to assess pain sensitivity (heat pain threshold [HPT]) and pain tolerance (heat pain suprathreshold [HPST]). Women with DED showed a significantly lower HPT and HPST than those without dry eye disease.
Management of DED symptoms is complex, and physicians need to consider the holistic picture, rather than simply treating ocular signs, Jelle Vehof, PhD, and colleagues were quoted as saying.
