Insights
Glaucoma patients in Jamaica often present with advanced disease and poor treatment adherence. Further research is needed to develop region-specific data and improve eye care equity.
Area of Science:
- Ophthalmology
- Public Health
- Medical Imaging
Background:
- Glaucoma is a leading cause of irreversible blindness globally.
- Characterizing glaucoma in specific populations is crucial for targeted interventions.
- Jamaica's largest public eye care facility serves a diverse patient demographic.
Purpose of the Study:
- To describe the clinical, demographic, and imaging characteristics of adult glaucoma patients at Kingston Public Hospital (KPH).
- To identify key features of glaucoma presentation in a Jamaican population.
- To inform strategies for improving glaucoma management in the region.
Main Methods:
- Retrospective, cross-sectional chart review of 324 adult glaucoma patients (2018-2023).
- Inclusion criteria: ≥2 ophthalmic exams and ≥1 high-quality optical coherence tomography (OCT) scan.
- Data collected: demographics, intraocular pressure (IOP), visual acuity, OCT parameters (optic nerve head, RNFL), visual field (VF) metrics, comorbidities, and treatment adherence.
Main Results:
- 51% of patients presented with advanced glaucoma; 17.3% reported consistent medication use.
- Common comorbidities: hypertension (80.3%) and diabetes (38.8%).
- Mean RNFL thickness: 75.2 ± 14.9 μm; mean cup-to-disc ratio: 0.73 ± 0.10. Moderate visual field loss observed, with worse outcomes in men.
Conclusions:
- Glaucoma in Jamaica is characterized by a high prevalence of advanced disease and low treatment adherence.
- Significant gaps exist in longitudinal monitoring of visual field progression.
- Need for prospective studies to establish ancestry- and region-specific OCT reference data for equitable glaucoma care.
Purpose:
To characterize the clinical, demographic, and imaging features of glaucoma among adults receiving care at Kingston Public Hospital (KPH) Ophthalmology clinic, Jamaica's largest public eye care facility.
Methods:
We conducted a retrospective, cross-sectional chart review of adult glaucoma patients seen at the KPH Ophthalmology Clinic between January 2018 and March 2023. Included patients had documentation of at least two comprehensive ophthalmic examinations and one high-quality optical coherence tomography (OCT) scan (signal strength ≥ 6). Extracted data included demographics, intraocular pressure (IOP), visual acuity, OCT-derived optic nerve head and retinal nerve fiber layer (RNFL) parameters, visual field (VF) metrics, glaucoma severity, comorbidities, and self-reported treatment adherence. Comparisons were performed by age group (< 40 vs. ≥ 40 years) and sex.
Results:
A total of 324 patients (619 eyes) were included (mean age 58.3 ± 12.3 years; 66.0% female). At presentation, 51.0% had advanced-stage glaucoma, and only 17.3% reported consistent medication use. Hypertension and diabetes were common comorbidities (80.3% and 38.8%, respectively). Mean Goldmann IOP was 22.0 mmHg, mean RNFL thickness was 75.2 ± 14.9 μm, and mean cup-to-disc ratio was 0.73 ± 0.10. VF indices demonstrated moderate functional loss, with worse mean deviation among men. Longitudinal VF data were limited; only 17% of patients had more than one documented test, limiting cohort-wide assessment of functional progression.
Conclusion:
This clinic-based characterization of glaucoma in Jamaica reveals a high burden of advanced disease at presentation, low treatment adherence, and gaps in longitudinal monitoring, supporting the need for prospective studies to develop ancestry-and region-specific OCT reference data and improve equitable glaucoma care.
