Abstract

Taking eyedrops according to prescription is an important factor in the management of glaucoma. In this study, we investigated th causes, forms, and sociological variables associated with patient noncompliance and measures to improve compliance. We surveyed 184 patients using eyedrops as prescribed for glaucoma to evaluate compliance. The frequency of missing eyedrops were as follows. Fifty patients missed taking eyedrops more than once per week, 17 missed once per 2 weeks, therefore, 39% of the total patients missed taking eyedrops more than once per 2 weeks. We defined the good compliance group as those who missed taking eyedrops once or less per month and inquired into the factors affecting compliance. Lesser frequency of taking eyedrops and no experience of side effects, resulted in good compliance, whereas age, sex, duration of disease, the standard of living, understanding the doctor's prescription, marital status, and fear of blindness did not affect compliance. Regarding understanding the doctor's prescription, 74.7% of the patients answered 'fully understood', however, 64.3% of the patients answered 'No' when questioned 'Did you press your punctum or close your eyes for five minutes after taking eyedrops?' showing discrepancy between performance and understanding the doctor's prescription. Therefore, we have to make to make an effort to promote compliance by considering these factors in treatment of glaucoma patients.
