Abstract
Glaucoma currently accounts for 11% of irreversible visual loss worldwide. Due to many factors, patients do not access the glaucoma care pathway and present late with poor vision, while many are undiagnosed or untreated. These factors may be personal-level dispositions or Institutional-level dispositions, limiting the awareness, diagnosis, and treatment of glaucoma or adherence to medications or follow-up clinic visits. This scoping review followed the JBI methodology for scoping reviews and was pre-registered on the open science platform (https://osf.io/wqx57/?view_only=727eb6c803764509a2809e5d0794e214). The PUBMED, EMBASE, WEB OF SCIENCE, AJOL, and GOOGLE SCHOLAR databases were systematically searched for studies published in English between 1990 and June 2023. Data were extracted and analysed along a conceptualised framework of factors limiting access to glaucoma care in Nigeria. Of the 336 records retrieved, 13 studies were included in this scoping review. These included one (1) mixed method (quantitative/qualitative) study, three qualitative studies, and nine quantitative studies spanning 2008-2022 covering eight states and 2,643 sampled respondents. Nine studies reported personal-level dispositions limiting glaucoma care, including low levels of education, unemployment, gender, living distance from the hospital, cost of care, and faith/religion. Four reported institutional-level dispositions, including the lack of proper equipment and expertise to diagnose or manage glaucoma. The factors limiting Glaucoma care in Nigeria are varied and may act alone or combined with other elements to determine the awareness or knowledge of glaucoma, uptake of glaucoma surgery, medication adherence, or clinic follow-up. While most of these factors limiting glaucoma care in Nigeria may be amenable to policy, a bottom-up approach is needed to improve the community's awareness and uptake of glaucoma services. A shift from the over-dependence and reliance on tertiary hospitals, which are often far away from the people who need them, is required to bridge the information and service gap currently being witnessed.

Surv Ophthalmol 2023; 68:567-577. [PMID: 37004793 PMCID: PMC10875963 DOI: 10.1016/j.survophthal.2023.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 03/22/2023] [Accepted: 03/27/2023] [Indexed: 04/03/2023]
Abstract
In this scoping review, we examine underlying causes of loss to follow-up for chronic (glaucoma) and acute (corneal ulcers) eye conditions using the Penchansky and Thomas access to care framework. We explore barriers by World Health Organization income levels and by studying geographical location. We identified 6,363 abstracts, with 75 articles retrieved and 16 meeting inclusion criteria. One article discussed barriers to follow-up care for people with corneal ulcers, and the other 15 were for people with glaucoma. The most frequent barriers to care were affordability, awareness, and accessibility. The international studies had a greater percentage of studies report acceptability as a barrier to loss to follow-up. Countries with universal healthcare included affordability as a loss to follow-up barrier, emphasizing that cost goes beyond the ability to pay for direct treatment costs. Understanding and addressing barriers to follow-up care can aid the goal of continued care and decrease the risk of poor outcomes and vision loss.

Abstract
PRECIS In the absence of prophylactic anti-inflammatory therapy, anterior chamber inflammation (characterized by cells and less commonly flare) is minimal and transient after selective laser trabeculoplasty in Afro-Caribbean glaucoma patients. PURPOSE The purpose of this study was to characterize the prevalence, severity, and duration of anterior chamber inflammation (cells and flare) following selective laser trabeculoplasty (SLT) in Afro-Caribbean eyes with primary open-angle glaucoma (POAG). METHODS In total 144 eyes of 72 POAG patients underwent first-time 360-degree SLT treatment following washout of all topical medications in the prospective West Indies Glaucoma Laser Study. No anti-inflammatory therapy was used post-SLT. Anterior chamber cells and flare were characterized pre-SLT after medication washout, and 1 week, 6 weeks, and 3, 6, 9 and 12 months post-SLT using the standardized methodology described by the Society for Uveitis Nomenclature (SUN) in which cells and flare are each graded on a scale of 0-4+ using specific slit-lamp settings. RESULTS Mean cell scores in both right and left eyes rose significantly (P<0.0001) from baseline to week 1 after SLT before returning to baseline values at all subsequent time points. Mean flare scores in right eyes (P=0.0185) but not left eyes (P=0.1816) rose from baseline to week 1 after SLT before returning to baseline values at all subsequent time points. Cells appeared in 40.3% of eyes and flare appeared in 9.7% of eyes after SLT. One subject developed bilateral symptomatic anterior iritis one day postoperatively and reported a previously undisclosed history of recurrent iritis; the iritis resolved with topical steroid therapy. CONCLUSIONS SLT in Afro-Caribbean people with POAG is associated with mild, short-lived and self-limited anterior chamber inflammation. Routine anti-inflammatory therapy to suppress posttreatment inflammation after SLT is unnecessary in this population.

JOURNAL OF WEST AFRICAN COLLEGE OF SURGEONS 2020; 10:16-22. [PMID: 35814968 PMCID: PMC9267041 DOI: 10.4103/jwas.jwas_48_22] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 04/07/2022] [Indexed: 11/11/2022]
Abstract
Background: Community eye outreach (CEO) screening is an important model which has been widely employed to detect eye conditions such as cataract and glaucoma in high-risk groups. There is a dearth of data on the eye care practices of glaucoma patients identified using this model in South West Nigeria. Objectives: The aim of this article is to assess the eye care practices, knowledge, and attitudes of glaucoma patients/suspects identified at CEO screenings in Nigeria. Design of the Study: This was a mixed method study with quantitative and qualitative approaches. Setting in Which the Study Took Place: The study was carried out at 24 outreach screening centres in communities in Oyo and Osun states. Materials and Methods: The quantitative component of this study was a cross-sectional survey of patients with suspected glaucoma identified at routine CEO in South West Nigeria. Surveys were administered by trained personnel and gathered information on knowledge and attitudes towards glaucoma. The qualitative component consisted of structured interviews with providers to assess their knowledge and perspectives of glaucoma patients’ attitudes and behaviours. Results: A total of 1881 patients were screened at 24 outreach screenings in South West Nigeria, among which 120 glaucoma cases/suspects were identified. Fifty-six (46.7%) of the glaucoma patients were aware of glaucoma, but only 39 (32.5%) patients could answer at least one knowledge question correctly. Predictors of awareness of glaucoma were minimum of secondary school education [adjusted odds ratio (OR) 8.76; 95% confidence interval (CI) 3.18–24.13] and having had an eye check-up in the past (adjusted OR 5.87; 95% CI 1.92 – 17.92). Patients said cost and ‘not knowing the disease was serious’ were reasons for not following up at the main hospital. Health workers interviewed said that cost and poor knowledge were the main reasons glaucoma patients frequently attended free outreach screening events rather than seeking definitive care. Conclusion: Although CEO screenings improve access to eye care, provision of appropriate health education programs and strengthening of the health insurance scheme are needed to improve its impact in glaucoma care.

Abstract
PURPOSE Severe corneal disease contributes significantly to the global burden of blindness. Corneal allograft surgery remains the most commonly used treatment, but does not succeed long term in every patient, and the odds of success fall with each repeated graft. The Boston keratoprosthesis type I has emerged as an alternative to repeat corneal allograft. However, cost limits its use in resource-poor settings, where most corneal blind individuals reside. METHODS All aspects of the Boston keratoprosthesis design process were examined to determine areas of potential modification and simplification, with dual goals to reduce cost and improve the cosmetic appearance of the device in situ. RESULTS Minor modifications in component design simplified keratoprosthesis manufacturing. Proportional machinist time could be further reduced by adopting a single axial length for aphakic eyes, and a single back plate diameter. The cosmetic appearance was improved by changing the shape of the back plate holes from round to radial, with a petaloid appearance, and by anodization of back plate titanium to impute a more natural color. CONCLUSIONS We have developed a modified Boston keratoprosthesis type I, which we call the "Lucia." The Lucia retains the 2 piece design and ease of assembly of the predicate device, but would allow for manufacturing at a reduced cost. Its appearance should prove more acceptable to implanted patients. Successful keratoprosthesis outcomes require daily medications for the life of the patient and rigorous, frequent, postoperative care. Effective implementation of the device in resource-poor settings will require further innovations in eye care delivery.

Abstract
Glaucoma is the leading cause of irreversible blindness in Africa. The condition is treatable but not curable. There are numerous obstacles to glaucoma care in Africa, including availability, accessibility and affordability of treatments, as well as medication nonadherence among patients. Medical therapy is costly relative to the average income in Africa and it requires daily self-dosing by patients. Surgery is of limited availability in many regions in Africa, and a high proportion of patients refuse surgery because it is expensive. Selective laser trabeculoplasty (SLT) proves to be a favorable alternative to medical or surgical care, as it is highly effective and safe in people of African descent, more cost-effective than medical therapy, quick and easy to perform, and portable. The procedure also requires no postoperative care, thus obviates the issue of nonadherence. In uncontrolled studies, SLT has a high response rate and it lowers intraocular pressure by 30% to 40%, which exceeds the goal in international guidelines for initial therapies. The African Glaucoma Consortium (AGC), a member-driven stakeholder collective, has been formed in part to develop the infrastructure for continent-wide improvements in glaucoma care. It embraces SLT as a potential key tool in their development plans. The mission of AGC includes improving clinical care by educating existing and new health care professionals to expand the provider network, by conducting trials to identify optimal care strategies for glaucoma in Africa, and by facilitating the development of an integrated network of Centers of Excellence to bring SLT and other crucial glaucoma therapies to communities throughout Africa.

Abstract
OBJECTIVES The present study was conducted to develop an instrument for measuring adults' glaucoma knowledge levels and to establish the instrument's validity and reliability. MATERIALS AND METHODS The study group consisted of 811 persons aged 40-80 years who presented to primary health care institutions and did not have a glaucoma diagnosis. A 27-item questionnaire measuring level of glaucoma knowledge was created by the study team. Following expert consultation, it was structurally evaluated. The difficulty index and discrimination index were calculated for each item. Factor analysis was used to determine construct validity, Cronbach's alpha internal consistency coefficient and item-total correlations were calculated to determine reliability. Confirmatory factor analysis was used to assess the extent to which the factor structure of the scale fit. We analysed correlation with the National Eye Health Education Program (NEHEP) Eye-Q scale in order to evaluate the validity of the scale. RESULTS The final glaucoma knowledge level questionnaire comprised 10 items in one dimension. The discrimination index and difficulty index ranged between 0.28 to 0.65 and 33 to 61%, respectively. According to factor analysis, the Kaiser-Meyer-Olkin score was 0.760 and Bartlett's test indicated p<0.001. Confirmatory factor analysis showed acceptable scale fit and fit indices. Validity assessment revealed a positive correlation between the total score of the items of the NEHEP scale and glaucoma knowledge level questionnaire score (r=0.522; p<0.001). Scores were higher in participants who were aged 40-64, living in the city, had education level of high school or above and had previous eye examination or intraocular pressure measurement. CONCLUSION The glaucoma knowledge level questionnaire has the distinction of being the first valid and reliable scale for assessing level of glaucoma knowledge in Turkey.

Abstract
Glaucoma in Africa is sometimes referred to as the silent thief of sight. In Nigeria, glaucoma is common, it is serious, ophthalmologists face many constraints in managing it, people do not even know they have it until it is advanced, patients do not understand or comply with treatment after they are diagnosed and the poor are more likely to be glaucoma blind. Available evidence indicates that the health system in Nigeria is failing to meet the needs of patients with glaucoma. Based on evidence, we propose future directions for improving services for glaucoma care in Nigeria, and the implications for policy and programmes to control glaucoma blindness, using a health system-oriented approach. Three complementary strategies are required: (i) strengthening clinical services for glaucoma-by developing models of glaucoma care, improving clinical treatment options, making medicines and equipment available, financing glaucoma care and training eye care workers; (ii) introducing initiatives for earlier detection of glaucoma in the clinic and approaches in the community and (iii) strengthening health system governance. Glaucoma is a complex disease to manage and addressing it as a public health problem is challenging. However, we need to change the paradigm to recognise that glaucoma is a potentially avoidable cause of blindness in Africa.

Abstract
BACKGROUND Glaucoma in sub-Saharan Africa has been described as a surgical disease because of the high cost of medical treatment, poor compliance and unavailability of medications. AIM This study reports the long-term outcomes and complication rates following trabeculectomy with 5-fluorouracil in a case series of Nigerians. DESIGN OF STUDY This was a retrospective, observational, non-comparative case series. SETTING University College Hospital, Ibadan, Nigeria. METHODOLOGY Each patient had complete ophthalmic evaluation. The post-operative intraocular pressure (IOP), visual acuity outcomes and post operative complications were assessed. The World Glaucoma Association consensus on surgical outcome was used to evaluate surgical outcome. RESULTS Of the 292 patients who presented with glaucoma during this period, a total of 47 eyes of 31 patients (10.6%) had trabeculectomy with 5-FU. The mean presenting intraocular pressure (IOP) was 31.8±12.2mmHg. At three years post-operatively, 48.5% achieved complete success without medications while 90.9% achieved success with or without medications at an IOP cut off of ≤21mmHg. At the same time point of 3 years and an IOP cut off of ≤15mmHg, 63.6% achieved success with or without medications. At a mean post-operative period of 43± 19.6 months, (range 12-86 months), mean IOP had reduced from a preoperative mean of 31.8±12.2mmHg to 15.4±4.7mmHg (P<0.001). CONCLUSION Trabeculectomy with 5-Fluorouracil is effective in the long term in reducing IOP with minimal complications in this population of Nigerians.
