Background: Information on the visual health of school children can assist in developing strategies to reduce preventable causes of visual impairment (VI) and maintain good vision.Aim: This study aimed to determine the magnitude and causes of VI amongst basic school children aged 6–16 years in the Bono Region of Ghana.Setting: The study site included five basic schools in 12 administrative districts of the Bono Region of Ghana.Methods: A multistage random sampling technique was used to enrol 645 participants from five selected public schools.Results: Overall, 1.4% of the sample had some form of VI that was worse than mild or no VI, and ocular conditions were present amongst 45.1% of the participants. Uncorrected refractive error (URE) was found amongst 9.8% of the study participants (n = 63) and was an important cause of VI. Other ocular conditions detected in the sample included allergic conjunctivitis (n = 174), cataract (n = 2) and keratoconus (n = 2). Overall, 632 (98.0%) participants recorded a visual acuity (VA) of 20/20 – 20/60, 11 (1.7%) participants had a VA of 20/60 – 20/200, 1 (0.15%) participant had a VA of 20/200 – 10/200 and 1 (0.15%) participant had a VA of 10/200.Conclusion: The presence of ocular conditions was high amongst the study participants (45.1%). However, the prevalence of VI was found to be low (1.4%) with URE being the most common cause. This study supports the need to intensify awareness of ocular conditions and/or VI in basic schools through regular vision health screening and education.

A number of factors and conditions hinder and restrict access to the health care system and its different services; these barriers to access put at risk the health of people by affecting adequate processes. Objective: To carry out a literature review on barriers to access to the health care system and visual health services in Colombia and around the world. Methodology: A literature review was carried out based on a search of the Medline, ScienceDirect, and Pubmed databases, as well as indexed public health journals and the websites of the Local Health Authority, the World Health Organization, the Pan American Health Organization, the UNESCO, and the Brien Holden Vision Institute. Results: The main barriers related to demand, both in general services and in visual health, are the lack of perception on the need for service and lack of economic resources; at the offer level, the existing policies constitute a real obstacle. Conclusions: Awareness-raising in the population, together with the implementation of health policies that grant equal access to health care services, are fundamental to prevent people from being affected, to a large extent, by barriers related to demand or offer, regardless of their location or level of income.
