ABSTRACT
OBJECTIVE: To determine the frequency, demography, aetiology and mechanisms of ocular injuries associated with childhood traumatic cataract in Nigeria. METHODS: A retrospective multicentre study conducted across ten child eye health tertiary facilities in Nigeria between January 2017 and December 2021. Clinic records of all children aged 0-17 years who had been diagnosed with cataract at the various participating centres were reviewed. Information collected include: biodata, mechanism of injury; laterality, place of injury; object responsible; person responsible; duration before presentation and surgical intervention. RESULTS: A total of 636 out of 1656 children (38.4%) had traumatic cataracts during the study period. Their mean age was 109.4 ± 45.2 months with a male-to-female ratio of 2:1. Most injuries were unilateral, two (0.3%) children had bilateral involvement. Only 78 (15.3%) children presented within 4 weeks of the injury. Closed globe injuries were responsible for the traumatic cataract in 475 (74.7%) children, while open globe injuries were more likely to present within 24 h (P < 0.001). The commonest objects of injury were cane, sticks, plant, wood and play materials. Self-inflicted injuries occurred in about 82 (13%) children while 407 (64.0%) were caused by close relatives and contacts. The location where trauma occurred was home in 375 (59.8%) and school in 107 (16.8%) children. CONCLUSION: This multicentre study demonstrates that more than one-third of all childhood cataracts in Nigeria are trauma-related and majority are due to closed globe injuries. Public health interventions to reduce the occurrence of ocular trauma and to encourage early presentation after trauma are advocated.
ABSTRACT
Background: The access to universal eye health is still poor in many developing countries. There are various initiatives to address this problem, but the initiatives are majorly under the support of external funding. This study reports community outreaches supported by community-based organisations over a 7-year period in resource-poor settings in Ilorin, Kwara State, Nigeria. Aims and Objectives: This study aims to describe the processes/procedures, output, and funding of eye care services provided in the rural communities over a 7-year period. The study seeks to present the process, demographical profiles, disease pattern, challenges, and recommendation in finding the core area of development to improving eye care services for these communities as well. The setting of this research work is 65 rural communities around the Ilorin metropolis of Kwara State, Nigeria. The design of the study is a retrospective review. Materials and Methods: This is a descriptive study of 7-year community eye outreaches in Ilorin, Nigeria. Data were analysed with IBM-Statistical Package for Social Sciences (SPSS-20). Results: A total of 65 communities with 235 visits were carried out between the years 2013 and 2019, with a total of 13,661 persons screened. The major eye diseases seen were refractive errors, allergic conjunctivitis, cataract, and pterygium. Common surgical eye problems were cataract, pterygium, and glaucoma. Community-based organisation direct financial support built up from USD 855 in 2013 and totalled USD 27,250 in 2019. Community-based organisation funding is an alternative and useful means of meeting the unmet needs of eye care in resource-poor communities. Subsidised care was provided to community-sourced patients due to support by local community-based organisations. This subsidy assisted in reaching the outreach numerical goal. However, it was still inadequate to meet the total needs as seen by the lower number of clinical care and surgeries rendered against the total numbers identified. Conclusion: To achieve sustainable and wider coverage of care, a combination of local source and external funding is required. This study shows that community eye care programme can be supported by local or indigenous sponsors in a sustainable manner, thereby contributing considerably to addressing prevalent cases of avoidable blindness.
ABSTRACT
OBJECTIVES: Retinopathy of prematurity (ROP) will become a major cause of blindness in Nigerian children unless screening and treatment services expand. This article aims to describe the collaborative activities undertaken to improve services for ROP between 2017 and 2020 as well as the outcome of these activities in Nigeria. DESIGN: Descriptive case study. SETTING: Neonatal intensive care units in Nigeria. PARTICIPANTS: Staff providing services for ROP, and 723 preterm infants screened for ROP who fulfilled screening criteria (gestational age <34 weeks or birth weight ≤2000 g, or sickness criteria). METHODS AND ANALYSIS: A WhatsApp group was initiated for Nigerian ophthalmologists and neonatologists in 2018. Members participated in a range of capacity-building, national and international collaborative activities between 2017 and 2018. A national protocol for ROP was developed for Nigeria and adopted in 2018; 1 year screening outcome data were collected and analysed. In 2019, an esurvey was used to collect service data from WhatsApp group members for 2017-2018 and to assess challenges in service provision. RESULTS: In 2017 only six of the 84 public neonatal units in Nigeria provided ROP services; this number had increased to 20 by 2018. Of the 723 babies screened in 10 units over a year, 127 (17.6%) developed any ROP; and 29 (22.8%) developed type 1 ROP. Only 13 (44.8%) babies were treated, most by intravitreal bevacizumab. The screening criteria were revised in 2020. Challenges included lack of equipment to regulate oxygen and to document and treat ROP, and lack of data systems. CONCLUSION: ROP screening coverage and quality improved after national and international collaborative efforts. To scale up and improve services, equipment for neonatal care and ROP treatment is urgently needed, as well as systems to monitor data. Ongoing advocacy is also essential.
ABSTRACT
PURPOSE: Routine eye examination in early life is not the practice in most resource-limited countries. Delay in the presentation for eye problems is typical. Community health officers are often consulted by caregivers for all health problems during routine immunization and well-baby clinics in primary healthcare for children aged 0-2 years. This study evaluated the value and limitation of interview, Bruckner red reflex test, and instrument vision screener by noneye care middle-level staff of rural and urban well-baby immunization clinics, in early detection and referral for childhood eye disorders. MATERIALS AND METHODS: This was a cross-sectional study. Middle-level community health workers (CHWs) working at well-baby/immunization clinics were trained to perform vision screening using interview of caregivers, red reflex eye examination with ophthalmoscope, and instrument vision screener (Welch Allyn SPOT™ Vision Screener) without mydriatic drugs during routine immunization of children aged 0-2 years. IRB approval was obtained. RESULTS: Over a 6-month period in 2017, the CHWs screened 5609 children. Overall, 628 (11.2%) patients were referred to the tertiary child eye care unit. Referred cases included cataract, glaucoma, congenital nasolacrimal duct obstruction, ophthalmia neonatorum, retinoblastoma, and significant refractive errors. Referral from the interview of mothers was enhanced if specific questions to elicit visual function were asked. Bruckner red reflex test was more effective than instrument vision screener in the detection of cataract and life-threatening diseases such as retinoblastoma. Instrument vision screener was preferred by parents and better at detecting amblyopic risk factors. CONCLUSION: Preschool vision screening during routine immunization by primary healthcare workers in resource-limited settings was effective. Whenever instrument vision screener does not give any recommendation during screening, consider vision- or life-threatening pathology and refer.
ABSTRACT
Chronic recurrent multifocal osteomyelitis (CRMO) has rarely been associated with uveitis. The authors report a case of new CRMO in a 15-year-old boy with HLA-B27 positive chronic anterior uveitis controlled with methotrexate. This case highlights a potential association between chronic uveitis and CRMO. [J Pediatr Ophthalmol Strabismus. 2019;56:e38-e40.].

PURPOSE: The study compared ocular biometry values using applanation and immersion techniques to determine the most applicable method for our tertiary training centre where personnel with different levels of experience and expertise in biometry take measurements used in calculation of required intraocular lens before cataract surgery. METHODS: The study was a prospective cross-sectional comparative study of different techniques of ocular biometry from diagnostic equipment (biometry probe 10 MHz Sonomed(®) A-scan (PACSCAN 300A, USA). Measurement variables were obtained among children and adults undergoing cataract surgery. Scleral (Prager) shell was used for the immersion technique followed by the contact technique by the same examiner. RESULTS: The biometry values of 92 eyes of 92 adult were taken. Their ages ranged from 18 to 95 years with a mean of 64.7 (SD ± 12.9) years. There were 55 (59.8%) males and 37 (40.2%) females, with a male to female ratio of 1.5:1. Average axial length (22.0-24.4 mm) eyes were the most common eyes measured in 75 (81.5%) of the cases. The means of the axial lengths biometry values with immersion and contact technique were 23.66(±1.36) and 23.46 mm (±1.46); the axial length differences was 0.2 ± 0.26 mm (range 0.0-0.94 mm) and statistically significant (95% CI of the Difference 0.15 to 0.26, p = 0.000). The Standard deviation SD (mm) of Individual Eye Axial Length showed a mean of 0.03 ± 0.04 (0.0-0.3) mm for immersion and for contact technique 0.14 ± 0.12(0.0-0.6)mm. CONCLUSION: There was a significant difference in ocular biometry measurement with the contact and immersion ultrasound techniques. The immersion technique had better repeatability, thus it is ideal in a training hospital setting in a typical in sub-Saharan Africa who have limited resources to employ a dedicated person to do biometry; and where the different operators of A-scan machines have different levels of experience and expertise.
