Indeed, conservative estimates of the

annual incidence of glaucoma in other African countries have been higher at approximately 400 cases per 1 million of the population.11 This suggests technical support the true annual incidence of glaucoma could be double what is being diagnosed by the glaucoma services in Botswana. Conclusions from this study must be interpreted cautiously. Glaucoma is a challenge to the eye services in the country, as some patients have poor access to services, limited awareness and understanding of the disease, and limited treatment options from the resources available. Further research into the incidence and prevalence of glaucoma in Botswana is required, as well as the need to establish effective treatments in eye health service.

Air pollution has been linked to the development and exacerbation of a number of health problems. This link seems especially clear for cardiovascular and respiratory diseases such as ischaemic heart disease, heart failure, asthma, influenza and lung cancer.1–4 It is well established that the ambient levels of air pollution in a region can have an impact

on the health status of the population which inhabits it.5 Air pollution levels should therefore be taken into account when considering the wider determinants of public Cilengitide health and the impact that changes in air pollution might have on the health of a population. Warwickshire is an English county within the UK approximately 112 km North-West of London. The issue of air pollution has been highlighted in Warwickshire recently by the setting up of Air Quality Management Areas (AQMAs) in a number of different parts of the county. These are specific areas in the county that have been identified as places where, without a focused local council strategy to reduce air pollution, future government targets for air pollutant concentrations may not be met.
