Diabetes can affect the eye in a number of ways. The most serious of these involve the Retina in your eye. The blood vessels in the Retina (the light sensitive area at the back of the eye) can become “leaky” or blocked, leading to a condition called Diabetic Retinopathy. This condition may lead to bleeding or scarring in the centre of the Retina, which if severe cases can lead to loss of sight. In the early stages you cannot tell if your eyes have been damaged by Diabetes. That is why it is important that you have your eyes screened every year, so that if any problems are found then treatment can begin, to stop them getting worse. Once a year people with Diabetes will be invited via letter to attend for their eyes screening. Primary Grading – This is undertaken by one of the Retinal Screeners who have been trained to the required National Standard. If the primary grading assessment shows no abnormalities then a letter is sent directly to the patient and GP Secondary Grading – Secondary grading is undertaken if any type, or severity, or abnormality is detected during Primary grading. In addition to this, a random 10% of all images identified as normal on Primary grading undergo secondary grading, for quality assurance purposes Arbitration Grading – This grading stage provides a quality assurance measure. For any images where there is a difference in opinion between the primary and secondary grading, the image is graded for a third time. Our aim is to provide a screening appointment that is as convenient as possible, therefore, alongside the fixed screening sites at Barnsley and Rotherham Hospitals, we also attend a number of community venues. Please contact us for further information regarding our community venue locations and clinic details. Information for outpatients Find out what you need to know if you are visiting the hospital.
