Abstract:
Introduction: At least 2.2 billion individuals suffer from glaucoma, which is an
asymptomatic chronic eye illness leading to complete blindness. Increased intraocular
pressure is a clinical contributor to glaucoma; thus, to reduce intraocular pressure, ocular
hypotensive eye drops are most commonly used. Unlike oral medications, patients’
knowledge on self-administration can lead to a great prognosis. As a result, good
awareness, and support from healthcare professionals about eye drop instillation is crucial
to lead a quality life in glaucoma patients.
Objective: To assess the knowledge of self-administration of eye drop instillation and the
associated factors among glaucoma patients attending Eye clinic, Teaching Hospital
Jaffna.
Methodology: A hospital-based descriptive cross-sectional study was carried out in 2023.
A systematic random sampling method was used to identify 161 participants and an
interviewer-administered questionnaire was used to collect the data. The chi-square test
was performed in SPSS to find the association with knowledge and possible factors. Ethical
approval was obtained from the Ethics Review Committee, Faculty of Medicine,
University of Jaffna.
Results: The total sample size was 161. The respondent rate was 87.5%. The age of the
participants varied from 26 years to 83 years old with a mean age of 58.93 (SD=15.40).
More than half of the participants (54%) were female and the majority of them were
married (76.4%). A small portion of participants (33.6%) have educational qualifications
above ordinary level. Nearly half of the participants (48.4%) had poor knowledge about
self-eye drop instillation and only 11.8% of the participants had good knowledge. Although
64.6% of the patients were unable to identify the name of the drug, they were using them.
The factors associated with knowledge were age (p<0.001), educational qualification
(p<0.001), employment status (p<0.001), previous health education (p<0.05) and duration
of disease (p<0.05).
Conclusion: Knowledge on self-administration of eye instillation is poor among glaucoma
patients who attend the Eye Clinic, Teaching Hospital Jaffna. It is recommended that
healthcare providers should be more attentive towards patients’ knowledge regarding eye
drop administration. Interventions such as demonstration programs, proper health
education and distributing handouts can be carried out in future.
