Compliance with treatment of patients with chronic open-angle glaucoma.

The compliance with treatment of 168 patients with chronic open-angle glaucoma was studied. 42% of the patients missed at least some of their medication. Patients were more likely to miss doses in the middle of the day than in the morning or evening. Two factors found to improve compliance were the knowledge of the name of their eye disease and the possible ill effects of having no treatment. Patients were more likely to be poor compliers ifthey had been prescribed medication to be used 3 or 4 times a day than if they had been told to use treatment only twice a day.
