A Study on Adherence of Anti-Glaucoma Medications in Adults – An Observational Hospital based Study

Abstract

Introduction: Glaucoma is chronic progressive optic neuropathy which causes irreversible visual filed loss. Antiglaucoma
medication is the mainstay of treatment due to recent advances in the field. Due to increased life expectancy and availability
of newer investigation technology for early diagnosis of glaucoma, duration of treatment is long. Strict adherence is
required to prevent progression.
Aim: We aim to assess factors affecting adherence in a tertiary care setting.
Materials and Methods: 40 diagnosed cases of glaucoma, who were using on medication at least for 6 months, were
enrolled in the study after proper consent. All patients were asked about nature of drug intake based on standardized
questionnaire. Data were analysed using epi-info7 software.
Results: 40% study population were non adherent; it was comparable in males and females (p=.5). The factors like age,
sex, number of drugs didn’t show statistically significant association. Only parameter with significant association is
higher educational level (p=0.004).
Conclusion: Drug adherence is a complex process; various factors need to be considered before prescribing medication. In
case of chronic, progressive, blinding disease like glaucoma, educating patient about need to strict drug dosing, possible
side effects, cost-effectivity and regular follow up is required.
