How will my opthalmologist check for eye problems if I have diabetes?

At your appointment, you'll read from an eye chart. The doctor will use a tool called an ophthalmoscope to look at your retina. Your doctor might use eye drops to dilate your pupils and view the retina with lenses and a special light called a slit lamp. A test called fluorescein angiography can show changes in your retinal blood vessels. For this test, the doctor injects a fluorescent yellow dye into one of your veins and then photographs your retina as the dye outlines the blood vessels. Your eye exam will likely also include a check for glaucoma and cataracts.
