We installed our first digital camera in 2003 and quickly placed retinal cameras in all of our practices. They have proved to be a tremendously useful way to inspect and document the retinal appearance.
The cameras use infra red light for focusing and alignment before the flash so that we can usually capture good pictures without the use of drops. One of the great assets of the camera is the 30 degree field of view. Much better than the traditional technique of fundus inspection with a direct ophthalmoscope. If a patient finds it hard to keep their eyes open or stationary during the examination a still photograph can be a great help.
The retina is one of the few areas of the body where blood vessels can be directly observed. Abnormalities of their calibre, reflections and crossings can indicate vascular disease. Retinal haemorrhages and exudates can arise from a number of conditions including diabetes. The camera records these features very well. Our retinal photography should not be seen a substitute for attending the national diabetic retinopathy retinal screening programme. We recommend that all diabetics attend their retinal screening when called and approach their GP if they are not enrolled in the screening programme (unless already having such checks under the care of an ophthalmologist).
There is a £10 professional fee to adults for this entirely optional retinal camera service.
The drusen formed in Macular Degeneration can be photographed with digital retinal photography. Macular changes can be investigated in detail using higher resolution techniques for the retinal layers such as optical coherence tomography (OCT) which is available in our Barton practice..
