BACKGROUND: Glaucoma is a significant cause of blindness worldwide. It is more common, presents earlier and is more aggressive in those of African descent. Non-adherence and poor knowledge of glaucoma is a significant barrier to treatment and has been associated with low health literacy. We aim to establish the factors contributing to late presentation, treatment non-adherence and disease progression in glaucoma patients in Sierra Leone. This will help better understand the challenges eye services face, highlight fields requiring development in patient-clinician interaction and identify areas or specific vulnerable patient groups in which resources should be focused. METHODS: Prospective, consecutive recruitment of 120 patients with POAG attending the Lowell and Ruth Gess Eye Hospital and the Connaught Government Teaching Hospital, Freetown, Sierra Leone between February and April 2020. Data were collected from 3 sources: (1) review of clinical notes since first attendance, (2) semi-structured interviews and (3) assessment of study participant's drop instillation technique using a structured checklist. Descriptive statistics was performed for demographic data and other relevant data points. Logistic regression was used for analysis of target variables. RESULTS: The average age was 62 years with more males (52.6%). Agricultural workers and informal street traders represented 13.2% of participants' occupation. 25.8% of participants had no formal school, and 47.4% had either a degree or a diploma. This is out of proportion with the general population and may represent a hidden demographic of glaucoma patients. Drop instillation technique was successful in 52% of study participants. Notable responses to the questionnaire were 30% of patients did not know the name of their eye condition and 22% had no knowledge of glaucoma. CONCLUSION: Investment in a wide-ranging and robust screening programme and public health campaigns targeting these vulnerable groups and high-risk individuals, for example with a positive family history, alongside improved patient education and staff training is required to improve glaucoma care. Support from government, international organisations and the private sector is required to reduce the economic burden of blindness in Sierra Leone.
