Background: Low/middle-income countries have the highest burden of blindeness and visual impairment, which directly affects the children and indirectly affects their community. Furthermore, the number of blind years suffered by children with low vision or blindness creates a self-perpetuating ripple effect on their development, health and the socio-economic development of their communities. This systematic review aims to interrogate the existing evidence on the prevalence and causes of blindness and visual impairment in Nigerian children to provide evidence to drive health policy. Methods: This was a systematic review without meta-analysis (SwiM) using a narrative synthesis of the evidence reported using the PRISMA guidelines. All primary cross-sectional studies (in English) reporting the prevalence and causes of visual impairment among Nigerian children under 20 years old between 2003 and 2022 were included in this review. PUBMED, AJOL, BASE and ProQuest databases were searched for eligible studies between 6 June and 15 July 2023. The quality of the included studies was assessed using the AXIS tool. Results were extracted and summarised using descriptive statistics. Visual impairment and blindness using the presenting visual acuity in the better eye were reported using the WHO classification. Results: Seventeen studies, involving 16,924 children from 13 states across five geo-political zones in Nigeria, were included in the final analysis of this review. The prevalence of visual impairment was 3.9%, 2.7% and 0.3% for mild, moderate and severe visual impairments, respectively, due to ametropia, cataracts, glaucoma, etc. The prevalence of blindness was 0.2% due to cataracts, corneal scars and optic atrophy. Conclusion: Blindness and visual impairment is still a significant clinical and public health burden among Nigerian children. Hence, there is still a need for clinicians, especially opthalmologists, public health specialists, policy-makers, and other relevant stakeholders to intensify efforts towards the prevention and control of this burden.

The sustainable development goals (SDGs) of providing universal health coverage for all and ending poverty by 2030 aim to make healthcare accessible and available for all, irrespective of status, gender or race. Unfortunately, access to universal healthcare is still hampered by preventable inequalities, especially amongst the Low-Middle income countries (LMICs). Cataracts are the leading cause of preventable blindness globally, affecting over 17 million people; 80% of these people reside in the LMICs and cost-effective cataract surgery is the only way to treat it. However, barriers exist that prevent access to cataract surgery amongst these people. Despite widespread reports of these barriers to cataract surgical access, the complex relationships between the barriers and cataract surgical access have yet to be fully explored by researchers or policy-makers. A randomised control trial involving three groups is proposed and presented in this paper to test the relationship between well-known barriers to cataract surgical access in resource-poor communities and programmes designed to overcome them.

Objectives: To investigate the effects of the COVID-19 pandemic on childhood immunisation programmes in West African Countries.Design: The study was a systematic review of available evidence of the impact of the COVID-19 pandemic on childhood immunisation programmes in West AfricaSetting: An online literature search was conducted using PubMed, Embase, Scopus and Web of Science for all peer-reviewed longitudinal, descriptive, observational, prospective and retrospective studies on childhood immunisation programmes in West Africa published between January 2020 and May 2022Participants: All West African childhood immunisation programmes.Interventions: NoneMain Outcome Measures: Change in immunisation volumes during the COVID-19 pandemicResults: 353 studies were identified during the literature search, and eight were included in this review. The studies comprised six quantitative studies, one mixed-method (quantitative/qualitative) study and one qualitative study. Changes to immunisation services ranged between 53% and 52% for MCV and Penta3 vaccines in Guinea, lasting longer than August 2020, to 0.3% and 1% in Liberia for BCG and MCV vaccines lasting no longer than May 2020. Factors contributing to the observed disruptions in vaccine coverage during the pandemic included the fear of contracting the virus expressed by caregivers and healthcare workers and general misinformation about the COVID-19 virus.Conclusion: While the changes were greater than 50% and lasted longer in some countries, they were brief and short-lived in others, emphasising that the COVID-19 pandemic's effect in each country differed.
