Eye condition
High blood sugar damages the small blood vessels of the retina. It causes no symptoms in the early stages, which is why everyone with diabetes needs a dilated eye check every year. Found early, treatment can prevent most serious vision loss.
At a glance
Have a diabetic eye check every year, even when vision seems fine. Get same-day eye care for sudden loss of vision, a shower of floaters or a curtain across vision.
The doctor decides which you need. Every test is done at the clinic.
