If you have diabetes, follow the dilated-eye-exam schedule recommended by your care team even when vision seems clear.
Changes can be silent
Diabetic retinopathy develops when diabetes affects tiny blood vessels in the retina. Early stages may have no symptoms. Later changes can blur vision or lead to vision loss. A good score on a central acuity chart does not prove the retina is healthy.
Control of blood glucose, blood pressure, and cholesterol helps protect health, but eye exams remain necessary. The right interval depends on the individual and the findings of previous exams.
What screening looks for
A clinician may use a dilated exam and retinal photographs or scans to look for changes. Some settings use authorized AI tools to analyze retinal images for referable disease; those tools have a defined purpose and do not replace every part of eye care.
Common questions
Can vision feel normal with diabetic retinopathy?
Yes. Early diabetic retinopathy can have no noticeable symptoms, so waiting for blur can miss a chance to intervene. Follow the exam schedule your diabetes and eye-care teams recommend.
Does a retinal photograph replace a dilated exam?
Photography can be valuable for screening, and AI may assist in certain settings. Whether it substitutes for a particular visit depends on the care pathway, image quality, and your risk. It does not assess every eye problem.
For persistent changes or symptoms, arrange an eye examination. Seek urgent medical care for sudden vision loss, a new curtain or shadow, many new floaters with flashes, severe eye pain, an eye injury, or sudden double vision.
