Dry, Itchy Eyes Could Mean More Than Just Allergy
Patients with allergic eye symptoms can also have concomitant dry eye disease, and the combination of the two conditions often means that symptoms are more numerous and more severe. The treatment of patients suffering from both allergic conjunctivitis and dry eye disease includes discontinuation of many oral antihistamines, as they have anticholinergic properties that exacerbate dryness.
@nimmy Dry eye disease was more prevalent in the ophthalmology patients than in the allergy patients (51.6% vs 37.5%). However, allergy patients with concomitant dry eyes were more likely to have more severe disease — defined as having more than 4 symptoms — than ophthalmology patients (42.6% vs 15.8%).
