The Health Technology Assessment Programme is accepting stage 1 applications to their commissioned workstream for this primary research topic:
19/38 Scanning confocal ophthalmoscopy for diabetic eye screening
The prevalence of diabetes in the UK continues to increase and amongst other things,
complications of diabetes can lead to sight loss. The NHS Diabetic Eye Screening Programme was
established to systematically screen anyone over the age of 12 with type 1 or type 2 diabetes for
signs of retinopathy each year.
Depending on the severity of any abnormalities found, patients are referred to specialist ophthalmic
care for further assessment and treatment as required.
The screening programme in England uses two-field digital photography of the retina and requires
mydriatic dilatation of the pupil. Programmes in Wales and Northern Ireland are broadly similar. In
Scotland different eye screening protocols are used.
Scanning confocal ophthalmoscopy technologies are of interest to the NHS screening
programmes. It is an imaging technology, which does not routinely require pupil dilatation and
different machines can operate in a number of different modes: narrow, normal, wide field or ultra
wide field. How well it performs in a screening programme and how these compare to existing
digital photography has not yet been adequately assessed.
