A latest suggestion for enhanced services to reach the news desk is from Durham University in the shape of a diabetes finger prick test. Its studies found that 32 per cent of high risk group patients needed further medical advice after blood glucose test trials within optical practices. Redcar-based optometrist Faye McDearmid said testing was a great opportunity, but rightly cautioned that funding was not yet available. And should NHS funds become available, many are unconvinced it would be sufficient to cover the extra cost of such a service, never mind help make money. Indeed, an extra revenue stream is only a welcome one if it proves profitable, whether it is diabetes, glaucoma or red eye clinics. It remains unclear whether enhanced services will equate to enhanced revenues. Meanwhile, a survey by Vision Express this week revealed that only 30 per cent of parents never take their child for an eye test, while the Optical Confederation's Children's Eye Health campaign and marketing drives by the multiples seek to re-address the balance. It compares to 90 per cent of children being taken to the hairdressers every year, which would be expected, but spare a though for the remaining 10 per cent who never have a haircut. Now they must be really be struggling to see.
