Diabetes is an increasingly major cause of eye problems including diabetic retinopathy, cataracts, muscle problems, and retinal detachments. The underlying cause of each of these can be related to the increase blood sugar levels which are associated with poorly controlled diabetes. As these problems become more prevalent, the treatment options have expanded, and many can be reversed or improved through treatment and lifestyle changes.
How Diabetes Impacts the Eyes
Diabetes results in changes in the eyes when the blood sugar level remains high for an extended period of time as the body cannot break down and store glucose appropriately.
After time, this can lead to damage to the blood vessels themselves and result in weakening of the blood vessel walls.
In diabetic retinopathy, the blood vessels in the eyes may break and have blood leak out due to this weakening.
Other problems may result from the interruption of blood supply due to this type of rupture or blockage including a stroke which impairs the muscles controlling the eye movements.
Diagnosing Diabetic Eye Problems
Any time there are changes to vision or the eyes, especially in a diabetic patient, a comprehensive eye examination should be performed to identify the source of the changes.
In addition to an eye examination, brain imaging may be helpful if the root cause of the issue is a blockage in blood vessels in the brain or spinal cord.
Symptoms of Diabetic Eye Problems
There are a wide range of symptoms that can be related to a diabetic eye problem. Things ranging from blurred vision over time to sudden double vision or loss of vision can all be related to diabetes.
Given the variety of presentations, it is important to discuss all symptoms with your eye doctor and seek care quickly when a new symptom presents.
Treatment for Diabetic Eye Problems
Once there is a diagnosis made and the cause of an eye problem is identified as being related to the diabetes, treatment can begin.
Almost all treatment protocols will include some amount of lifestyle modification or systemic disease management alongside a primary care doctor to attempt to prevent additional problems both in the eyes and in the rest of the body from the diabetes.
Specific treatment for the eyes may also include injections of medication into the eye, surgical repair or treatment, or prescribing different glasses.
Can Diabetic Eye Problems Be Reversed
With the appropriate treatment and systemic management of the blood sugar, most of the changes from diabetes can be reversed.
While some changes – such as cataract formation or a retinal detachment – are not reversible and will require medical attention to improve the condition, other problems are manageable with good blood sugar control.
Your eye doctor will likely want to monitor you closely to watch for any changes or worsening symptoms while the blood sugar stabilizes, and any eye problems are improved over time.
Once the problem has been reversed or resolved, your eye doctor and primary care doctor will work together to determine the best course of action moving forward.

Diabetic retinopathy is a potentially serious eye condition that affects individuals with diabetes. Among its various forms, proliferative diabetic retinopathy (PDR) is the most advanced stage and requires immediate attention. In this blog, we will delve into the causes, symptoms, and treatment options for PDR to increase awareness and understanding of this sight-threatening condition.
What is Proliferative Diabetic Retinopathy (PDR)?
Proliferative diabetic retinopathy is a complication of long-term, poorly controlled diabetes. It is characterized by the abnormal growth of new blood vessels on the retina, the light-sensitive tissue at the back of the eye. These new blood vessels are fragile and prone to leaking blood and other fluids, leading to visual complications and potentially causing serious vision loss.
Causes and Risk Factors
The primary cause of proliferative diabetic retinopathy is prolonged, uncontrolled diabetes. Chronically high blood sugar levels can damage the blood vessels in the retina, triggering a cascade of events that lead to the growth of abnormal blood vessels. Additional risk factors for PDR include:
Duration of Diabetes: The longer an individual has diabetes, the higher the risk of developing PDR.
Poor Blood Sugar Control: Inadequately managed blood sugar levels significantly increase the likelihood of developing diabetic retinopathy, including PDR.
Hypertension: High blood pressure can exacerbate the progression of PDR and increase the risk of severe vision loss.
Poor Blood Cholesterol Control: High levels of cholesterol can contribute to the development and progression of PDR.
Symptoms of PDR
In its early stages, proliferative diabetic retinopathy may not cause noticeable symptoms. However, as the condition progresses, individuals may experience the following symptoms:
Floaters: The appearance of spots or dark strings in the field of vision caused by blood leakage into the vitreous, the gel-like substance in the center of the eye.
Blurred Vision: Blood leakage and swelling of the retina can lead to blurry or distorted vision.
Loss of Vision: In advanced stages, PDR can cause severe vision loss or even blindness if left untreated.
Fluctuating Vision: Vision may change throughout the day due to fluctuating blood sugar levels.
If you experience any of these symptoms, it is crucial to seek immediate medical attention from an eye care specialist or ophthalmologist.
Treatment Options for PDR
Prompt diagnosis and treatment are vital in managing proliferative diabetic retinopathy to prevent further vision loss. The following are common treatment options:
Laser Photocoagulation (Panretinal Photocoagulation): This procedure uses a laser to create small burns on the peripheral areas of the retina. The purpose is to shrink abnormal blood vessels and prevent their growth, reducing the risk of bleeding and vision loss.
Intravitreal Injections: Medications called anti-vascular endothelial growth factors (anti-VEGF) can be injected directly into the eye. These drugs help inhibit the growth of abnormal blood vessels and reduce the risk of bleeding and visual complications.
Vitrectomy: In cases where there is significant bleeding or severe traction on the retina, a surgical procedure called a vitrectomy may be performed. During this surgery, the vitreous gel is removed, and any scar tissue is carefully peeled away to restore retinal health.
In addition to these treatments, it is crucial for individuals with PDR to manage their diabetes effectively. This includes maintaining stable blood sugar levels, controlling blood pressure and cholesterol levels, and following a healthy lifestyle with regular exercise and a balanced diet.

With diabetic patients, it is crucial to prioritize their eye health by scheduling an annual dilated eye exam. This particular exam plays a vital role in managing their condition effectively. Unlike other parts of the body, the eye provides a unique opportunity to directly visualize and assess the state of active blood vessels through a non-invasive procedure. Here, we will explore why diabetic patients need a dilated eye exam each year and the significance it holds in the management of their condition.
The Link Between Vascular Damage and Diabetic Retinopathy
The development of diabetic retinopathy, a condition characterized by damage to the blood vessels in the retina, is a common occurrence in individuals with diabetes. The retina is the light-sensitive tissue at the back of the eye responsible for transmitting visual signals to the brain. When blood vessels in the retina are affected by diabetes, it can lead to leakage, swelling, or abnormal growth of blood vessels, resulting in vision problems and even blindness if left untreated.
However, diabetic retinopathy is not limited to the eye alone. Vascular damage caused by diabetes can also affect other parts of the body, such as the kidneys and extremities. This is where the importance of annual dilated eye exams becomes evident.
The Eye as an Indicator of Systemic Vascular Health
The eye, being the only part of the body where active blood vessels can be directly visualized with a non-invasive procedure, acts as a diagnostic window that reflects the state of the body’s overall vascular health. By examining the blood vessels in the retina, eye care professionals can identify early signs of vascular damage that may extend beyond the eye itself. This makes the annual dilated eye exam a valuable tool for managing diabetes comprehensively.
Annual Dilated Eye Exams as Additional Data Points for Diabetes Management
Having an annual dilated eye exam offers numerous benefits in the management of diabetes. Firstly, it provides an opportunity to detect and diagnose diabetic retinopathy at an early stage when treatment options are more effective. Early intervention can help preserve vision and prevent further complications.
Additionally, by identifying signs of vascular damage in the eye, healthcare providers can gain insight into the patient’s overall vascular health. Diabetic patients with diabetic retinopathy may be at a higher risk of developing other complications, such as kidney disease or peripheral vascular disease. Detecting these additional risks allows healthcare providers to implement appropriate preventive measures and adjust the patient’s treatment plan accordingly.
Why is Dilation Important
A comprehensive eye examination alone is valuable, but the dilation of the pupils to assess the entire retina is the most important portion of the examination for diabetic care.
When the pupils are dilated, the entire retina, along with all of the retinal blood vessels can be visualized and assessed for even small changes from the diabetes.
If dilation is declined, the view of the retina will be limited to the central portion of the retina and a large area will not be able to be assessed. When determining overall health and possibly adjusting care plans based on the retinal health, it is important to not miss this part of the retina in the assessment.
