Understanding Diabetic Retinopathy
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.

How Diabetes Affects the Retina
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.
.ecp-accordion.ecp-instance-4mkcYUwsev.ecp-accordion-theme-qanda .ecp-accordion-item:first-child{border-color: !important;}.ecp-accordion.ecp-instance-4mkcYUwsev .ecp-accordion-trigger{font-size:16px;color:#1b2432;background-color:#ffffff;border-width:0px;}.ecp-accordion.ecp-instance-4mkcYUwsev .ecp-accordion-trigger .ecp-accordion-trigger-icon-default{color:#1bbfdd;}.ecp-accordion.ecp-instance-4mkcYUwsev .ecp-accordion-trigger .ecp-accordion-trigger-icon-active{color:#a8a8a8;}.ecp-accordion.ecp-instance-4mkcYUwsev .ecp-accordion-content{padding:20px;} Blood Vessel Damage in the RetinaThe 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:
- Microaneurysms: Tiny bulges form in weakened vessel walls, which can rupture and leak blood into the retina.
- Retinal Hemorrhages: Small spots of bleeding appear as the vessel walls deteriorate, interfering with vision.
- Fluid Leakage: Damaged vessels leak fluid and proteins, leading to swelling in the retina, particularly in the macula-the area responsible for sharp central vision.
- Capillary Closure: Some retinal blood vessels become completely blocked, cutting off the blood supply to areas of the retina, leading to tissue damage and loss of function.
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:
- Leak large amounts of blood into the vitreous (the gel-like substance inside the eye), causing sudden vision loss.
- Form scar tissue that can contract and pull on the retina, potentially leading to a tractional retinal detachment, which may require surgery.
- Lead to increased eye pressure (neovascular glaucoma) when new blood vessels grow abnormally in the front of the eye, blocking normal fluid drainage.
One of the most significant ways diabetes affects the retina is through diabetic macular edema (DME). 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.
How Quickly Does Retinal Damage Develop?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. Key steps include:
- Keeping blood sugar levels within target ranges to reduce damage to blood vessels.
- Controlling blood pressure and cholesterol to maintain overall vascular health.
- Scheduling regular dilated eye exams (at least once a year) to detect early signs of damage.
- Avoiding smoking, as it 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.

- Neovascularization Elsewhere (NVE): Abnormal vessel growth extends to other parts of the retina.
- Vitreous Hemorrhage: Fragile vessels rupture, causing bleeding into the vitreous gel, leading to sudden vision loss or floaters.
- Tractional Retinal Detachment: Scar tissue forms as part of the healing process, pulling the retina away from its normal position and causing severe vision loss.
- Neovascular Glaucoma: Abnormal vessels can also grow in the front of the eye (on the iris), blocking normal fluid drainage and causing dangerously high eye pressure.
Unlike earlier stages of diabetic retinopathy, PDR often leads to more noticeable symptoms, including:
- Sudden appearance of floaters (dark spots or cobweb-like streaks in vision) due to bleeding inside the eye.
- Blurred vision or sudden vision loss if blood obscures the retina.
- Dark or empty areas in the field of vision.
- Distorted vision, particularly if the macula is affected.
- In advanced cases, complete vision loss if retinal detachment or severe bleeding occurs.
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:
- Fundus Examination: Using a slit-lamp and special lenses, an ophthalmologist inspects the retina for neovascularization and bleeding.
- Optical Coherence Tomography (OCT): High-resolution imaging that helps assess retinal thickness and detect associated macular edema.
- Fluorescein Angiography: A dye-based test that highlights abnormal blood vessel growth and leakage.
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.

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:
- Dilated Eye Exams: Special eye drops widen the pupils, allowing a clear view of the retina to detect early signs of damage.
- Optical Coherence Tomography (OCT): A high-resolution imaging scan that helps assess retinal swelling and structural damage.
- Fluorescein Angiography (FA): A dye-based test that highlights abnormal blood vessels, leakage, and areas of poor circulation in the retina.
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:
- Blood Sugar Control Guidance: Helping you understand the importance of maintaining stable blood sugar levels to prevent further damage to retinal blood vessels.
- Blood Pressure and Cholesterol Management: Addressing risk factors that contribute to worsening diabetic retinopathy.
- Regular Monitoring: Establishing a schedule for eye exams and imaging tests to track changes over time.
If diabetic retinopathy or DME progresses, our retina specialist provides the most advanced treatments available to preserve your vision. These include:
Anti-VEGF Injections
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:- Reduce swelling in the retina and macula.
- Slow or reverse vision loss caused by DME and proliferative diabetic retinopathy (PDR).
- Are administered in-office under local anesthesia with minimal discomfort.
Laser Therapy (Panretinal Photocoagulation & Focal Laser)
Laser treatment is highly effective in managing diabetic eye disease. Our retina specialist may recommend:- Panretinal Photocoagulation (PRP): A laser procedure that shrinks abnormal blood vessels in PDR, reducing the risk of bleeding and retinal detachment.
- Focal or Grid Laser Treatment: Targeted laser therapy to seal leaking blood vessels in DME, helping to stabilize or improve vision.
Vitrectomy Surgery for Advanced Cases
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:- Remove blood from the vitreous cavity, restoring clear vision.
- Eliminate scar tissue that pulls on the retina.
- Prevent further complications that could lead to permanent blindness.
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.

Retinopathy (NPDR)
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.
.ecp-accordion.ecp-instance-9MoupetgVv.ecp-accordion-theme-qanda .ecp-accordion-item:first-child{border-color: !important;}.ecp-accordion.ecp-instance-9MoupetgVv .ecp-accordion-trigger{font-size:16px;color:#1b2432;background-color:#fafafa;border-width:0px;}.ecp-accordion.ecp-instance-9MoupetgVv .ecp-accordion-content{padding:20px;} What Happens to the Retina in NPDR?In NPDR, prolonged exposure to high blood sugar levels weakens the tiny blood vessels in the retina, leading to:
- Microaneurysms: Tiny bulges in the retinal capillaries form due to weakened vessel walls. These may leak small amounts of blood or fluid into the retina.
- Retinal Hemorrhages: If microaneurysms rupture, they can cause small areas of bleeding within the retina.
- Hard Exudates: Deposits of cholesterol and other lipids that leak from damaged vessels and form yellowish spots in the retina.
- Soft Exudates (Cotton Wool Spots): Small, fluffy white spots on the retina caused by areas of poor blood flow and oxygen deprivation.
- Venous Beading: The veins in the retina become abnormally twisted and enlarged due to irregular blood flow.
- Capillary Closure: Some small retinal blood vessels become blocked, cutting off blood supply to certain areas of the retina, which can lead to vision loss over time.
NPDR is classified into different stages based on the severity of the retinal changes:
- Mild NPDR: Characterized by a few microaneurysms and small areas of hemorrhaging. Vision is usually not affected at this stage.
- Moderate NPDR: Increased number of microaneurysms, dot-and-blot hemorrhages, hard exudates, and mild venous abnormalities. Some patients may start to experience mild vision changes.
- Severe NPDR: Defined by the “4-2-1 rule”:
- Severe retinal hemorrhages in all four quadrants.
- Venous beading in at least two quadrants.
- Intraretinal Microvascular Abnormalities (IRMA) in at least one quadrant.
A major complication of NPDR is diabetic macular edema (DME), which occurs when damaged blood vessels leak fluid into the macula-the part of the retina responsible for sharp, central vision. DME can cause significant vision loss if untreated, even in patients with mild or moderate NPDR.Symptoms of DME include:
- Blurred or distorted vision.
- Difficulty reading or recognizing faces.
- Colors appearing faded or dull.
Many people with NPDR do not experience noticeable vision changes in the early stages. However, as the condition progresses, symptoms may appear, such as:
- Blurred or fluctuating vision.
- Dark spots or floaters in the field of vision.
- Difficulty seeing in dim lighting.
- A dark or empty area in the center of vision if DME develops.
Certain factors increase the likelihood of NPDR worsening over time. These include:
- Poor blood sugar control (high hemoglobin A1c levels).
- High blood pressure (hypertension).
- High cholesterol levels.
- Longer duration of diabetes.
- Smoking, which worsens blood vessel damage.
- Pregnancy (diabetic retinopathy can worsen during pregnancy).
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:
- Blood Sugar Control: Keeping A1c levels below 7% significantly reduces the risk of worsening diabetic retinopathy.
- Blood Pressure and Cholesterol Management: Controlling hypertension and high cholesterol helps protect retinal blood vessels.
- Regular Eye Exams: Monitoring NPDR closely allows for early detection of worsening disease.
- Lifestyle Modifications: A healthy diet, regular exercise, and smoking cessation improve overall vascular health.
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:
- Anti-VEGF Injections: Medications such as ranibizumab, aflibercept, or bevacizumab are injected into the eye to reduce fluid leakage and swelling in the macula.
- Laser Therapy (Focal/Grid Photocoagulation): A laser is used to seal leaking blood vessels and reduce swelling.
- Steroid Injections: In some cases, corticosteroids are used to manage inflammation and fluid buildup.
Since NPDR can progress to more severe forms of diabetic eye disease, patients should have regular follow-ups based on their condition:
- Mild NPDR: Yearly eye exams.
- Moderate NPDR: Exams every 6 to 12 months.
- Severe NPDR: Exams every 3 to 6 months due to the high risk of progression to PDR.

However, you may need to see a retina specialist if:
- Your eye doctor detects signs of diabetic retinopathy or macular edema.
- You experience sudden changes in vision, such as blurriness, dark spots, or floaters.
- You are diagnosed with moderate or severe diabetic retinopathy, which requires specialized care.
- You have a high risk of progression to proliferative diabetic retinopathy (PDR).
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:
- Keeping your blood sugar levels stable.
- Managing blood pressure and cholesterol to protect blood vessels.
- Getting annual eye exams to catch problems early.
- Seeking prompt treatment if you develop diabetic retinopathy.
Some symptoms indicate that diabetic retinopathy may be progressing rapidly and requires urgent care. You should see a retina specialist immediately if you experience:
- Sudden vision loss in one or both eyes.
- New or worsening floaters (dark spots or cobweb-like lines in your vision).
- Flashes of light, which may indicate retinal detachment.
- Severe blurriness that does not improve with blinking.
- A dark curtain or shadow in your vision, which may signal a retinal detachment.
- Pain or redness in the eye, which could indicate neovascular glaucoma.
Yes, while anyone with diabetes can develop diabetic retinopathy, certain factors increase the risk, including:
- Having diabetes for a long time-after 20 years, nearly 99% of type 1 and 60% of type 2 diabetics have some degree of retinopathy.
- Poor blood sugar control (high hemoglobin A1C levels).
- High blood pressure (hypertension).
- High cholesterol levels.
- Pregnancy-diabetic retinopathy can worsen during pregnancy.
- Smoking, which accelerates blood vessel damage.
- Ethnicity-studies show that African American, Hispanic, and Native American populations have a higher risk of developing severe diabetic eye disease.
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.
What can I do to prevent diabetic retinopathy?While there is no guaranteed way to avoid diabetic retinopathy, you can significantly lower your risk by:
- Keeping blood sugar levels within a healthy range (A1C below 7%).
- Monitoring and controlling blood pressure and cholesterol.
- Getting annual dilated eye exams to catch changes early.
- Eating a healthy diet and staying physically active.
- Avoiding smoking and excessive alcohol consumption.
- Following your doctor’s recommendations for diabetes management.
