Blood flow problems in the diabetic retina can cause serious vision issues if not managed properly. Our experienced eye doctors are here to guide you through effective monitoring and treatment tailored for your needs.
This guide covers the essentials of diabetes-related retinopathy, including its overview, stages, symptoms, causes, diagnostic methods, treatment options, preventative measures, and the importance of coordinated care.
Diabetes-related retinopathy is a condition that affects the blood vessels in the retina, the light-sensitive tissue at the back of your eye. It develops because high blood sugar levels damage and weaken these essential blood vessels, leading to leakage and the formation of new, fragile vessels that can further compromise your vision. This condition, while serious, can be managed with careful monitoring and timely treatment coordinated by our eye doctors.
Diabetes-related retinopathy is a complication of diabetes that gradually damages the small blood vessels in your retinas. As these vessels weaken, they begin to leak and eventually close off, which deprives the retina of needed oxygen and nutrients. In response, your eye may grow new blood vessels that are not fully developed and tend to leak, posing additional risks to your vision.
Your retina is a delicate layer of tissue that collects light and sends signals to your brain to form images. When high blood sugar levels are present over time, the walls of the retinal blood vessels become compromised. Initially, in a stage known as nonproliferative diabetes-related retinopathy (NPDR), these vessels develop tiny bulges and may start leaking fluid or blood. As the condition advances, the more severe stage of proliferative diabetes-related retinopathy (PDR) may occur as new, abnormal blood vessels form on the surface of the retina. These new vessels are prone to leakage and bleeding, which can lead to complications such as retinal detachment.
Diabetes-related retinopathy unfolds in two main stages, each with distinct changes in your retina. Understanding these stages can help you recognize the importance of early detection and treatment.
In the early stage of diabetes-related retinopathy, known as NPDR, the small blood vessels in the retina start to leak due to weakened walls from prolonged high blood sugar. The leakage can result in fluid accumulation, known as macular edema, which specifically affects the central portion of your retina responsible for clear, detailed vision. Although there may not be any noticeable changes in your vision initially, these subtle modifications are detectable during a dilated eye exam by our eye doctors.
As diabetes-related retinopathy progresses, it may evolve into proliferative diabetes-related retinopathy, the more advanced stage of the condition. Here, the retina begins to grow new blood vessels in response to the reduced oxygen supply; however, these vessels are brittle and prone to leakage. The leaking blood and fluid from these new vessels can lead to vitreous hemorrhage—a condition where blood accumulates in the gel-like substance of the eye—and even cause retinal detachment, both of which significantly elevate the risk of permanent vision loss.
In the early stages of diabetes-related retinopathy, many patients do not notice any symptoms. This lack of symptoms is why routine eye exams are so essential for individuals with diabetes. As the disease advances, you might notice changes that affect your day-to-day sight and quality of life.
Many patients may experience little to no vision changes at first, but it is important to be aware of potential early symptoms.
As diabetic retinopathy worsens, the symptoms generally become more pronounced and may include:
The primary cause of diabetes-related retinopathy is prolonged high blood sugar, which damages the small blood vessels that supply your retina. Over time, these vessels become leaky or completely blocked, triggering a cascade of events that result in the formation of abnormal vessels. This ongoing process is strongly linked with the overall management of your diabetes and related health conditions.
At the core of diabetes-related retinopathy is the body's struggle to manage elevated blood sugar levels. Over time, consistently high blood sugar can have numerous negative effects on your body, particularly on the tiny blood vessels throughout your retina. Our eye doctors emphasize that good diabetes control is critical in preventing or delaying the complications associated with retinopathy.
Aside from high blood sugar, several other factors may increase your risk for developing diabetes-related retinopathy:
Because many patients do not experience symptoms early on, a thorough and regular eye examination is essential for detecting diabetic retinopathy. Our eye doctors use a comprehensive dilated eye exam to carefully inspect the back of your eyes, including your retina, for any signs of damage.
During a dilated eye exam, special instruments are used to provide a detailed view of your retina. The dilation process allows our eye doctors to look for early changes such as:
These findings can be present even in patients who are not yet experiencing noticeable vision problems, highlighting the importance of regular annual or more frequent exams for those with diabetes.
If initial examinations raise concern for diabetic retinopathy, our eye doctors may recommend further tests. One such test is the fluorescein angiogram, during which a special dye is injected into your bloodstream to highlight the blood vessels in your retina. This test allows us to capture detailed images that can pinpoint the areas where leakage or abnormal vessel growth is occurring. Such early detection methods are critical in planning the most effective treatment strategy.
Although diabetic retinopathy is a lifelong condition, early detection and timely treatment can significantly slow its progression and reduce the risk of permanent vision loss. Managing diabetes through lifestyle changes and medical therapies is crucial, and our eye doctors work closely with you to monitor both your eye health and overall diabetic management.

Since high blood sugar is the primary trigger for diabetic retinopathy, keeping your blood sugar levels as close to normal as possible can help prevent or delay damage to your retinas. Here are some strategies that have been shown to help:
Once diabetic retinopathy is detected, several eye-specific treatment options may be recommended. Although these treatments are not a cure, they can help slow the progression of the disease and prevent substantial vision loss:
Our eye doctors tailor treatment options to your specific condition, working closely with you and your primary care provider to ensure that both your diabetes and your eye health are managed effectively.
Prevention is always preferable to treatment when it comes to diabetes-related retinopathy, and there are several proactive steps you can take to safeguard your vision. Regular follow-up appointments and open communication with our eye doctors can make a significant difference in early detection and effective management.
Maintaining control over your diabetes and monitoring your overall health are the cornerstones of preventing complications from diabetic retinopathy:
If you have diabetes, taking an active role in your health begins with scheduling regular eye exams and adhering to your diabetic treatment plan. This vigilance not only helps in the early detection of changes in your vision but also informs our eye doctors about any adjustments needed to better manage your eye health. It is essential to view these appointments not only as a precaution but as an opportunity to keep your eyes functioning at their best.
