BackgroundUnconventional settings, outside general medical practice, are an underutilised resource in the attempt to identify the large numbers of people with undiagnosed diabetes worldwide.
AimThe study investigated the feasibility of using optometry practices (opticians) as a setting for a diabetes screening service.
Design and settingAdults attending high street optometry practices in northern England who selfreported at least one risk factor for diabetes were offered a random capillary blood glucose (rCBG) test. Those with raised rCBG levels were asked to visit their GP for further investigations.
ResultsOf 1909 adults attending practices for sight tests, 1303 (68.2%) reported risk factors for diabetes, of whom 1002 (76.9%) had rCBG measurements taken. Of these, 318 (31.7%) were found to have a rCBG level of ≥6.1 mmol/l, a level where further investigations are recommended by Diabetes UK; 1.6% of previously undiagnosed individuals were diagnosed with diabetes or pre-diabetes as a result of the service. Refining the number of risk factors for inclusion would have reduced those requiring screening by half and still have identified nearly 70% of the new cases of diabetes and pre-diabetes.
ConclusionScreening in optometric practices provides an efficient opportunity to screen at-risk individuals who do not present to conventional medical services, and is acceptable and appropriate. Optometrists represent a skilled worldwide resource that could provide a screening service. This service could be transferable to other settings.

18Likewise, optometrists (opticians) are providers of routine, non-emergency care and may be accessed by those who are not receiving medical care. The age of onset of presbyopia and the subsequent deterioration in near vision coincides with the age that screening for diabetes is recommended by both Diabetes UK and the American Diabetes Association (ADA). This again may provide opportunities for optometrists to provide tests to those who may not access other healthcare services, particularly if they have no other medical problems.Optometrists provide eye health care worldwide and have the potential to provide services in both developed and developing countries. In the UK, 17 million sight tests are performed yearly, over one-third on people aged 60 years or over. 19 Optometrists are in a position to ask patients about diabetes risk factors during the course of a sight test. In Australia, it has been shown that around 80% of optometrists always or often ask patients aged over 40 years about diabetes. 20 Optometrists may be in a good position to reach a section of the population that may no...
