Diabetes causes damage to the fine blood vessels throughout the body, including those at the back of the eye. The damaged blood vessels can leak fluid and blood into the retina, leading to vision loss and blindness. The risk of diabetic eye disease increases with the time since onset of diabetes and when diabetes (sugar levels) are not well controlled.
What does a diabetic eye examination involve?
A routine diabetic examination will involve applying eye drops that temporarily dilate (enlarge) your pupils. This is important so that the whole retina can be examined. A report of the examination results are then provided to your GP.
It’s best you don’t drive for a few hours after the examination and to bring some sunglasses on the day.
What would I see if my eyes were affected by diabetes?
In the early stages, it may be difficult to notice any changes in your vision. At later stages, you may experience: blurry vision, headaches, fluctuating vision (clear some days, blurry other days), eye strain and glare sensitivity.
