title: Alkaline tear pH in ocular rosacea.
abstract: We compared the tear pH values of 44 normal, healthy volunteers, 20 patients with ocular disorders other than rosacea, seven patients with untreated, active ocular rosacea, and five patients with tetracycline-treated ocular rosacea. The group with untreated, active ocular rosacea had significantly more alkaline tear pH values than the other groups tested. In patients with tetracycline-treated ocular rosacea, tear pH values were not significantly different from those of normal subjects.
