The test is called Diabtic Retinopathy Screening, and is safe and a definate test to undertake every year, the special photographs take the picture of inside the eye and at the retina, they are looking for changes that accur and they are a alert to any possible eye problems. They are annual and when you go have an eye test as well, to check on the overall sight of your eyes, both of these are free to diabetics. There is no pain, and just be careful when walking about afterwards.
The pictures are clear and after they have been examined by 2 people to check the results, you will then be written to giving you the results, if everything is fine then, they will be incontact in a year for the next screening session. Please dont be worried it is part of the diabetic care package, the other parts will be shown to you.
