ABSTRACT
Objective:
To determine adherence to glaucoma eye drops in patients from Glaucoma Project (Ministry of Health) by Morisky scale of 8 items.
Methods:
We conducted a cross-sectional study through a questionnaire applied to 237 patients diagnosed with glaucoma regularly enrolled in the Glaucoma Project at Institutode Olhos de Maceio, adapting the Morisky scale, already validated in Portuguese, for eyedrops. The variables were adherence to antiglaucoma eyedrops, age, sex, race, glaucoma diagnosis time, eyedrops number used, systemic diseases, education, subjective vision (categorized in bad, reasonable or good) and the factors correlated with poor adherence. Statistical analysis between variables was performed with the statistical test Chi-square test for categorical variables and test Mann-Whitney test for continuous outcomes, considering a 5% significance level.
Results:
The rate of adherence to the glaucoma drops was 54%. The age and number of drops (p = 0.02 and 0,03 respectively), and quality of vision (p<0,001) were statistically significant for the inappropriate use of the therapy and the most common reason both adherent group as the non-adherent was forgetfulness (23% and 76,15% respectively).
Conclusion:
Using the Morisky scale adapted to antiglaucoma eyedrops the adherence was 54%.
