Social, Educational and Medical Aspects after Cataract Surgery of Bilaterally Blind Children in Kinshasa-Perception of Parents and Children.

The study investigated the influence of bilateral cataract surgery on the social and educational development of previously bilaterally blind children in Sub-Saharan Africa (SSA), where the prevalence of blindness due to cataract is higher than in high-income countries. The views of both, parents and children, were evaluated with structured interviews based on a newly developed questionnaire related to surgery, follow-up, and family life after surgery. The mean age of the children at interview was 14.4 ± 8.1 years, with 27 females and 26 males. Satisfaction with the outcome of the surgery was reported by 91% of parents. Parents would recommend surgery, because of the children being happy and able to act more independently, with personal, educational and familial factors essentially contributing to the reported satisfaction. The results also showed that 85.0% of children did not wear eyeglasses. Reasons given were mainly cost-related, but also included limited communication between families and health institutions. Providing and maintaining a high-quality and accessible pediatric cataract surgery and healthcare service for follow-up is a major requisite to reduce childhood blindness in SSA. Our study proved the necessity and effectiveness of a community-based rehabilitation program that cares about each individual child, whatever his or her social background.

Online Faculty Development on Curriculum Design in Simulation-based Education by International Collaboration - An Example from the Democratic Republic of the Congo.

PURPOSE: Faculty development for procedural specialists is intended to improve clinical education and surgical/procedural skills. Despite challenging in under-resourced settings, this may be enhanced by developing international collaboration agreements and supported by online learning experiences. The Congolese Society of Ophthalmology and the International Council of Ophthalmology agreed to collaborate on implementing an online educational program to form a community of practice (CoP) of ophthalmologists educators and enhance competence in curriculum design and simulation-based education (SBE) on cataract surgery. METHODS: Ten Congolese ophthalmologists, faculty for the "Centre de Formation Ophthalmologique pour l'Afrique Centrale" (CFOACF), participated in a group-mentored 12-webinar modular program on curriculum design, in 2019. Considering the geo-social-cultural learning environment, we developed a curriculum framework incorporating social constructivism and experiential learning principles to facilitate the implementation of learning. Educational strategies included flipped, practice-based and social learning, group mentoring, and individual and collective reflection opportunities. A CoP was virtually nurtured using WhatsApp. Program evaluation relied on (a) feedback survey per module and 3 months upon conclusion, (b) individual declarative knowledge assessment, and (c) group assignment to test competence improvement. RESULTS: The CFOACF formed a virtual CoP, commented on an enjoyable opportunity to develop scholar teaching competence, expressed intention in systematically building educational curricula design that includes active learning strategies and effective feedback and showed individual learning and team-competence improvement. CONCLUSION: This first iteration of our online faculty development program nurtured the formation of a CoP of ophthalmologists' educators and enabled to practice a scholar teaching approach, especially applied to SBE.

Ocular Morbidity-A Critical Analysis to Improve Outpatient Services in an Eye Department in a Sub-Saharan Megacity.

The aim of this study was to analyse outpatient services in an ophthalmic clinic of a church-run hospital providing secondary level care in an African megacity, paying special attention to the poorest users of the services. The range of examination was reviewed from 500 patient records of all ages consecutively chosen on random days attending the outpatient department for the first time in order to optimize workflow and to analyse the offered treatment modalities. Mean age was 41.9 ± 21.9 years, and 53.6% of the patients were female. Of the patients, 74.8% presented with visual impairment. The most frequent findings were refractive errors (35.8%), presbyopia (21.2%), allergic conjunctivitis (14.0%), cataract (13.2%) and glaucoma (6.4%). Patient management consisted of optical treatment (49.6%), surgery (11.4%) and medical treatment (39.0%). These results show the importance of the demand in refractive services and the need to train specific service providers. Knowing the frequencies of common conditions enables more appropriate diagnostic and treatment strategies, e.g., the importance of refractive errors, and should lead to improvements in training, staffing, therapeutics and patient outcomes. This approach can be applied to many other outpatient services and should be evaluated in light of the city's impoverished health outreach and educational situation.

Comparison of platforms for testing antibodies to Chlamydia trachomatis antigens in the Democratic Republic of the Congo and Togo.

Trachoma, caused by repeated ocular infection with Chlamydia trachomatis (Ct), is targeted for elimination as a public health problem. Serological testing for antibodies is promising for surveillance; determining useful thresholds will require collection of serological data from settings with different prevalence of the indicator trachomatous inflammation-follicular (TF). Dried blood spots were collected during trachoma mapping in two districts each of Togo and Democratic Republic of the Congo. Anti-Ct antibodies were detected by multiplex bead assay (MBA) and three different lateral flow assays (LFA) and seroprevalence and seroconversion rate (SCR) were determined. By most tests, the district with > 5% TF (the elimination threshold) had five-sixfold higher seroprevalence and tenfold higher SCR than districts with < 5% TF. The agreement between LFA and MBA was improved using a black latex developing reagent. These data show optimization of antibody tests against Ct to better differentiate districts above or below trachoma elimination thresholds.

Role of a Community-based Program for Identification and Referral of Pediatric Cataract Patients in Kinshasa, Democratic Republic of the Congo.

PURPOSE: The purpose of this study is to describe the methodology and to assess the effectiveness of a community-based rehabilitation (CBR) program to identify and refer children with blinding cataract for the management and surgery to reduce the burden of childhood blindness due to cataract in Kinshasa. METHODS: Church-based volunteers were trained to identify children with presumed eye disorders in their localities and households and to refer them for cataract identification by an ophthalmic nurse during parishes' visits. Volunteers were parishioners living in the quartiers where identification took place and worked as community workers with the CBR program. Nurses used a lamp-torch to rule out cataract. Selected children were referred to the tertiary eye health facility at St Joseph Hospital for diagnosis and management. RESULTS: Identification took place in 31 out of 165 parishes in the Archdioceses of Kinshasa from 2000 to 2016 and 11,106 children aged <16 years were screened. Among them, 1277 children (11.5%) were presumed to have cataract. Ninety-two children among them died before surgery; 107 children were lost to further follow-up and did not report to the CBR center for referral. Reasons given were change of home address, moving in their lieu of origin, death, and refusal of treatment by the parents. Finally, only 1078 children were referred to the pediatric ophthalmologist and 705 children (65.4%) were definitively diagnosed to have treatable cataract, while in 373 children (34.6%), cataract surgery was not indicated for several reasons. There was a positive history of familial cataract in 36 children (2.8%). CONCLUSION: Using church-based volunteers and ophthalmic nurses during community screening proved efficient in the identification and referral of pediatric cataract. Keeping regular identification activities in the community and maintaining high-quality and accessible pediatric cataract surgery services can help to clear up the backlog of cataract blind children.

Trachoma in the Democratic Republic of the Congo: Results of 46 Baseline Prevalence Surveys Conducted with the Global Trachoma Mapping Project.

PURPOSE: Trachoma was suspected to be endemic in parts of the Democratic Republic of the Congo (DRC). We aimed to estimate prevalences of trachomatous inflammation-follicular (TF), trichiasis, and water and sanitation (WASH) indicators in suspected-endemic Health Zones. METHODS: A population-based prevalence survey was undertaken in each of 46 Health Zones across nine provinces of DRC, using Global Trachoma Mapping Project methods. A two-stage cluster random sampling design was used in each Health Zone, whereby 25 villages (clusters) and 30 households per cluster were sampled. Consenting eligible participants (children aged 1-9 years and adults aged ≥15 years) were examined for trachoma by GTMP-certified graders; households were assessed for access to WASH. RESULTS: A total of 32,758 households were surveyed, and 141,853 participants (98.2% of those enumerated) were examined for trachoma. Health Zone-level TF prevalence in 1-9-year-olds ranged from 1.9-41.6%. Among people aged ≥15 years, trichiasis prevalences ranged from 0.02-5.1% (95% CI 3.3-6.8). TF prevalence in 1-9-year-olds was ≥5% in 30 Health Zones, while trichiasis prevalence was ≥0.2% in 37 Health Zones. CONCLUSION: Trachoma is a public health problem in 39 of 46 Health Zones surveyed. To meet elimination targets, 37 Health Zones require expanded trichiasis surgery services while 30 health zones require antibiotics, facial cleanliness and environmental improvement interventions. Survey data suggest that trachoma is widespread: further surveys are warranted.

Diabetic foot syndrome and corneal subbasal nerve plexus changes in congolese patients with type 2 diabetes.

BACKGROUND: To study the severity of diabetic neuropathy, diabetic retinopathy and grades of diabetic foot syndrome for correlations with corneal subbasal nerve plexus (SBP) changes in Congolese patients with type 2 diabetes. METHODOLOGY/PRINCIPAL FINDINGS: Twenty-eight type 2 diabetes patients with diabetes-related foot ulceration were recruited in a diabetic care unit in Kinshasa, Democratic Republic of Congo. Corneal SBP was investigated by confocal laser-scanning microscopy to analyse nerve fibre density (NFD) [µm/ µm²], number of branches [n] and number of connectivity points [n]. Foot ulceration was graded using the Wagner ulcer classification. Corneal sensitivity (Cochet-Bonnet), Neuropathy Symptom Score (NSS), Neuropathy Disability Score (NDS), ankle-brachial index (ABI) and ophthalmological status were evaluated. Foot ulceration was ranked as mild (Wagner 0-1: 13 patients/46.4%), moderate (Wagner 2-3: 10 patients/35.7%) and severe (Wagner 4-5: 5 patients/17.9%). The correlation between Wagner Score and NFD (p=0.017, r = - 0,454), NDS and NFD (p=0,039, r = - 0.400) as well as Wagner Score and HbA1c (p=0,007, r = - 0.477) was stated. Significant differences in confocal SBP parameters were observed between Wagner 0-1 and Wagner 4 5 (number of branches (p=0.012), number of connectivity points (p=0.001), nerve fibre density (p=0.033)) and ABI (p=0.030), and between Wagner 2-3 and Wagner 4-5 (number of branches (p=0.003), number of connectivity points (p=0.005) and nerve fibre density (p=0.014)). Differences in NDS (p=0.001) and corneal sensation (p=0.032) were significant between Wagner 0-1 and Wagner 2-3. Patients with diabetic retinopathy had significantly longer diabetes duration (p=0.03) and higher NDS (p=0.01), but showed no differences in SBP morphology or corneal sensation. CONCLUSIONS/SIGNIFICANCE: While confirming the diabetic aetiology of foot ulceration due to medial arterial calcification, this study indicates that the grade of diabetic foot syndrome correlates with corneal SBP changes and corneal sensation in patients in sub-Saharan Africa.
