Diabetic retinopathy is an eye condition caused by damage to the blood vessels in the retina due to high blood sugar levels. It is a common complication of diabetes and can affect both eyes. In its early stages, vision may not change much, but as the disease progresses, it can cause blurriness, floaters, or vision loss. Regular eye exams help detect changes before serious damage occurs.

In advanced stages, new fragile vessels may form and bleed into the eye. These changes blur vision and, if untreated, can lead to permanent loss of sight. Early treatment helps slow or stop progression.
The condition develops when prolonged high blood sugar damages the tiny vessels that supply the retina. Poorly managed diabetes, high blood pressure, and high cholesterol can increase the risk. Both type 1 and type 2 diabetes can cause it. Maintaining good blood sugar control helps protect the eyes.
Doctors perform a dilated eye exam to look for bleeding, swelling, or abnormal blood vessels in the retina. Imaging tests like fluorescein angiography and optical coherence tomography (OCT) provide detailed views of retinal changes. These tests help determine the stage of the disease and guide treatment decisions.
If you have diabetes, schedule routine eye exams even if your vision seems fine. You should also see an eye doctor immediately if you notice blurry vision, dark spots, or sudden vision changes. Diabetic retinopathy can progress silently, and early treatment helps prevent vision loss and protect long-term eye health.
Regular eye exams are one of the best ways to detect and manage eye diseases early. Many eye conditions develop gradually and may not show noticeable symptoms until they start affecting vision. Visiting an eye doctor routinely helps protect your eyesight and maintain good eye health over time.
Yes. Early stages can cause no noticeable vision change, which is why routine dilated eye exams matter for anyone with diabetes. Damage can be detected on imaging before you feel it. Catching it early gives more options to slow progression.
Many people with diabetes are advised to have at least yearly dilated eye exams, but frequency depends on findings, blood sugar control, and pregnancy status. Your eye doctor may recommend more frequent visits if retinopathy is present. Sticking to the schedule helps protect long-term vision.
Yes. Better long-term blood sugar control lowers the risk of progression, and managing blood pressure and cholesterol also helps. Even after retinopathy starts, good control can reduce the chance of worsening. Pair medical management with regular eye monitoring for the best protection.
Depending on stage and swelling, treatment can include anti-VEGF injections, laser therapy, or surgery for bleeding or traction. The right approach depends on whether there is macular edema, new vessel growth, or vitreous hemorrhage. Your retinal specialist will explain the goal of treatment and the expected follow-up plan.
