Alkaline tear pH in ocular rosacea.
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.
