“…Increased vigilance is required to identify patients who cannot instil their drops properly. As in the study by Winfield et al 24 our study has identified dyscompliance as a significant component of non-compliance. It is probably worthwhile for ophthalmologists to ask their patients to demonstrate how they instil their eyedrops and to emphasise proper application techniques.…”

Purpose To document the prevalence of non-compliance and to investigate patients' perceptions concerning glaucoma in a Greek cohort.Methods We investigated 100 consecutive patients referred to our glaucoma clinic and already treated for chronic glaucoma.Compliance and patients' insight were ascertained by two independent observers by means of a predetermined questionnaire. All patients were subsequently assessed for their ability to instil their eyedrops accurately.Results Fifty one per cent of our patients were not aware of the nature of glaucoma, but 80%were afraid it might lead to blindness.Clinically significant non-compliance (more than two doses missed per week) was established in 44% of our patients. Men and those using eyedrops more than 4 times a day were more likely to default. Non-compliant patients exhibited higher mean intraocular pressure (22.9 vs 18.5 mmHg; p > 0.001) and worse visual field loss (10.8 vs 7.0 dB; P = 0.008) compared with compliant patients.Involuntary non-compliance was also common in our group, with only 53% instilling their eye drops accurately.Conclusion Non-compliance is a significant limiting factor in glaucoma therapy in Greece.

“…Although we have not directly observed patient difficulty in using these medicines, we are aware of the impact this has on patient compliance. Winfield's study 4 found over half of the patients report some difficulty in using drops. A total of 21% of patients never administer their own eye drops and 13% could not expel a drop from a hypromellose bottle.…”

“…23 We modified the scale to be appropriate for glaucoma patients and eye drop use with input from four practicing ophthalmologists, 10 glaucoma patients taking glaucoma eye drops, the peer-reviewed literature, and results from our earlier work, 31 in which we asked over 300 glaucoma patients from four practices about their problems and concerns in using their glaucoma medications. [32][33][34][35] The main changes that were made to the medication self-efficacy scale in hypertensive patients scale were that the questions asking about specific side effects to anti-hypertensive medications were modified to reflect specific side effects of glaucoma medications. Also, we added a series of questions focusing on ability to use eye drops correctly.…”

Purpose The purpose of this study was to develop and evaluate the psychometric properties of (a) a glaucoma medication selfefficacy scale and (b) a glaucoma outcome expectations scale.Patients and Methods Two instruments were developed: a glaucoma medication selfefficacy scale and a glaucoma outcome expectations scale. Packets containing (a) the instruments and patient demographic questions and (b) a letter explaining the study were distributed to 225 glaucoma patients from three ophthalmology practices between August and December 2007. The instrument was completed by 191 patients for a response rate of 85%. Principal components factor analysis with a varimax rotation and Cronbach's a reliability were used to analyse the data. To assess discriminant validity, we administered the scales and two self-reported measures of adherence in a separate sample of 43 glaucoma patients who were currently using at least one glaucoma medication.Results Our results yielded a 21-item self-efficacy in overcoming barriers that might interfere with the use of glaucoma medications scale, a 14-item self-efficacy in carrying out specific tasks required to use eye drops correctly scale, and a four-item glaucoma outcome expectations scale. Results of the Cronbach's a reliability indicated that the scales are internally consistent. The selfefficacy scales were both significantly associated with two patient self-reported measures of glaucoma medication adherence, which show discriminant validity.Conclusions Eye care providers and researchers can use these scales to identify patients with low self-efficacy in using their glaucoma medications and patients who do not believe that following their eye care providers' advice can help their vision.
