Diabetic Retinopathy is a serious eye condition caused by diabetes, affecting the retina's blood vessels and threatening your vision. Find top retina specialists listed with Specialty Vision, dedicated to providing expert care and preserving your sight.
Diabetic Retinopathy is one of the most common complications of diabetes, arising from the damage that elevated blood sugar levels inflict on the tiny blood vessels supplying the retina. The retina, the tissue responsible for capturing light and transmitting visual signals to the brain, is especially vulnerable to the harmful effects of uncontrolled diabetes. Over time, the weakened vessels may leak fluid or blood, setting off a chain reaction that can ultimately impair vision.
Diabetes damages the retina by affecting the small blood vessels that supply it with oxygen and nutrients. Over time, high blood sugar levels weaken these blood vessels, making them more prone to leaking, swelling, or becoming blocked. This process leads to a condition called diabetic retinopathy, which can progressively impair vision and, if untreated, cause blindness. The damage occurs in stages, from early mild changes to severe retinal complications that threaten sight.
The retina relies on a fine network of capillaries to function properly. In a healthy eye, these blood vessels are tightly sealed, preventing unwanted leakage. However, when diabetes is uncontrolled, prolonged exposure to high blood sugar (hyperglycemia) damages the walls of these tiny vessels. This damage causes several changes:
As diabetes-related damage continues, the retina responds by trying to compensate. The body attempts to grow new blood vessels to replace those that are damaged or blocked. However, these new vessels are abnormal—fragile, leaky, and prone to breaking. This leads to a more advanced and dangerous form of retinal disease known as proliferative diabetic retinopathy (PDR). In PDR, these abnormal blood vessels can:
The timeline for diabetic retinal damage varies from person to person. However, studies show that after 20 years of diabetes:
Nearly 99% of people with type 1 diabetes will have some form of diabetic retinopathy.
Approximately 60% of those with type 2 diabetes will show signs of retinal damage.
While diabetes-related retinal damage is serious, it can often be slowed or prevented with proper management. Early detection and intervention are crucial. With prompt treatment, such as laser therapy, anti-VEGF injections, or surgery, diabetic retinopathy and its complications can be managed effectively to help preserve vision. Key steps include:
Keeping your blood sugar within target ranges helps reduce damage to the small blood vessels in your retina.
Managing blood pressure and cholesterol levels supports overall vascular health, which is vital for protecting your eyes.
Regular dilated eye exams (at least once a year) help detect early signs of retinal damage before significant vision loss occurs.
Not smoking is essential, as smoking worsens blood vessel damage and increases the risk of severe diabetic eye disease.
Proliferative Diabetic Retinopathy (PDR) is the most advanced stage of diabetic retinopathy. It occurs when widespread damage to the retinal blood vessels triggers the growth of new, abnormal blood vessels in an attempt to compensate for areas where circulation has been lost. While this process may seem like the body’s way of repairing the damage, these new vessels are fragile, prone to leaking, and can lead to severe vision-threatening complications, including bleeding into the eye, retinal detachment, and even total blindness if left untreated.
Unlike earlier stages of diabetic retinopathy, PDR often leads to more noticeable symptoms, including:
Early detection of PDR is critical in preventing irreversible vision loss. The condition is diagnosed through a comprehensive dilated eye exam, often combined with advanced imaging tests such as:
Because PDR carries a high risk of severe vision loss, early and aggressive treatment is necessary. Several options are available, each aimed at reducing abnormal blood vessel growth and preventing further complications.
Diabetic eye disease, including diabetic retinopathy and diabetic macular edema (DME), is a leading cause of vision loss in people with diabetes. However, with early detection, proper management, and timely treatment, vision loss can often be prevented or minimized. Our retina specialist plays a crucial role in protecting your sight by providing expert evaluation, advanced diagnostic testing, and state-of-the-art treatments tailored to your specific needs.
Many people with diabetic retinopathy do not experience symptoms in the early stages. This is why regular, comprehensive eye exams are essential for detecting changes in the retina before vision loss occurs. Our retina specialist conducts detailed evaluations using:
By identifying diabetic eye disease early, our specialist can recommend interventions that slow its progression and reduce the risk of severe vision loss.
Managing diabetic eye disease requires a personalized approach based on your level of retinal damage, overall health, and diabetes control. Our retina specialist works closely with you and your primary care physician or endocrinologist to develop a plan that includes:
If diabetic retinopathy or DME progresses, our retina specialist provides the most advanced treatments available to preserve your vision. These include:
Medications such as ranibizumab (Lucentis), aflibercept (Eylea), bevacizumab (Avastin), and faricimab (Vabysmo) target vascular endothelial growth factor (VEGF), the protein responsible for abnormal blood vessel growth and leakage. These injections:
Laser treatment is highly effective in managing diabetic eye disease. Our retina specialist may recommend:
In severe cases of diabetic retinopathy, where vitreous hemorrhage or tractional retinal detachment threatens vision, vitrectomy surgery may be required. Our retina specialist performs this procedure to:
Nonproliferative Diabetic Retinopathy (NPDR) is the earliest stage of diabetic retinopathy, where damage to the retinal blood vessels occurs but without the growth of new abnormal vessels. It is the most common form of diabetic retinopathy and can range from mild to severe. While NPDR may not initially cause noticeable vision changes, it can progress and lead to more serious complications, including diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR), which pose a greater threat to vision.
In NPDR, prolonged exposure to high blood sugar levels weakens the tiny blood vessels in the retina, leading to:
NPDR is classified into different stages based on the severity of the retinal changes:
At this stage, the risk of progressing to proliferative diabetic retinopathy (PDR) within a year is high.

Many people with NPDR do not experience noticeable vision changes in the early stages. However, as the condition progresses, symptoms may appear, such as:
Certain factors increase the likelihood of NPDR worsening over time. These include:
There is no direct treatment for NPDR itself, but the focus is on preventing progression to more severe stages. The key to managing NPDR is strict control of diabetes and associated conditions. Strategies include:
In most cases, NPDR does not require immediate medical intervention. However, if diabetic macular edema develops, treatment is necessary to prevent further vision loss. Available treatments include:
Since NPDR can progress to more severe forms of diabetic eye disease, patients should have regular follow-ups based on their condition:
A major complication of diabetic retinopathy is diabetic macular edema (DME), which occurs when damaged blood vessels leak fluid into the macula. The macula, the central part of the retina responsible for sharp vision, becomes swollen due to fluid leakage from damaged blood vessels. This swelling distorts vision, making it difficult to read, recognize faces, or see fine details. DME is a leading cause of vision loss in diabetic retinopathy and can occur at any stage of the disease. DME can cause significant vision loss if untreated, even in patients with mild or moderate NPDR.
If you have diabetes, you should see an eye doctor for a comprehensive dilated eye exam at least once a year. However, you may need to see a retina specialist if:
Early intervention by a retina specialist can help prevent vision loss by offering advanced treatments such as laser therapy or anti-VEGF injections.
Not necessarily. While diabetes increases the risk of vision loss, most people with diabetes do not go blind, especially if the condition is detected early and managed properly. You can protect your vision by:
If diabetic retinopathy progresses to an advanced stage without treatment, it can lead to permanent vision impairment or blindness.
Some symptoms indicate that diabetic retinopathy may be progressing rapidly and requires urgent care. You should see a retina specialist immediately if you experience:
These symptoms can be signs of vitreous hemorrhage, macular edema, or retinal detachment—all of which require immediate treatment to prevent permanent vision loss.
Yes, while anyone with diabetes can develop diabetic retinopathy, certain factors increase the risk, including:
In the early stages (nonproliferative diabetic retinopathy or NPDR), controlling diabetes can sometimes slow or even partially reverse some of the damage. However, once the disease progresses to the proliferative stage (PDR) or causes diabetic macular edema (DME), vision loss becomes more difficult to reverse.
Available treatments—such as anti-VEGF injections, laser therapy, and vitrectomy surgery—can slow progression, prevent further damage, and, in some cases, improve vision. However, the best way to protect your sight is to prevent diabetic retinopathy from worsening through early detection and diabetes management.
While there is no guaranteed way to avoid diabetic retinopathy, you can significantly lower your risk by:
Taking these steps can help prevent diabetic eye disease or slow its progression.
