Aims: Prevalence of glaucoma increases with age and this potentially blinding condition requires regular instillation of eye drops. But with aging itself and accompanying co-morbidities, self instillation of eye drops gets affected. This study was designed to study the subjective difficulties associated with self instillation of eye drops in glaucoma patients and to quantitatively assess their impact on intraocular pressure (IOP). Settings and Design: Prospective interventional study at primary eye care center. Materials and Methods: A total of 69 persons diagnosed with glaucoma or ocular hypertension (OHT), who were self instilling their eye drops, were included in this study. Patients were interviewed for subjective difficulties being faced during self instillation using a formatted questionnaire. The patients were then subjected to assisted eye drop instillation for 4 weeks. The change IOP and consumption of eye drop bottles were compared between self installation and assisted instillation periods. Statistical Analysis: Paired t-test was applied at 5% significance level to compare pre and post interventional change of parameters. Results: Fifty three percent of patients reported subjective difficulties while self instilling their eye drops. Non-compliance was self-reported in 18% of the patients. The IOP dropped by 10-13% (P-value < 0.0001) and consumption of eye drop bottles was 14% (P-value < 0.0001) higher during self instillation. Conclusion: Assisted eye drop instillation may be beneficial to achieve better IOP control.
