In some diabetics, but certainly not all, there can be leakage from the retinal
blood vessels.
The images below are photographs of the back of the eye of persons' with this condition
captured by
Digital Retinal Photography.
In the first image, leakage shows as red or yellow spots or larger areas which can
damage vision. In this particular eye the patient was unaware of any problem.
This emphasises the importance of regular eye examinations
In the second image, some leakage from the retinal blood vessels can be seen in
the form of small red spots as before. However, previous leakage has been reduced
by using a laser and this can be seen as a circle of light dots in the central part
of the retina. This works almost like a spot welder.
