In State College, where long winters and screen-heavy routines are part of daily life, your eyes already face enough challenges. For the 1 in 10 residents living with diabetes, the risks are even higher.
Diabetic eye disease is one of the leading causes of blindness in working-age adults, but it’s also highly manageable when caught early. That’s why Advanced Eye Care Services is highlighting the importance of comprehensive eye exams and awareness this November.
What Is Diabetic Eye Disease?
Diabetic eye disease develops when high blood sugar damages the blood vessels in the retina, leading to issues like leaking fluid, swelling, and reduced oxygen supply. These changes often happen gradually and without symptoms at first, making the condition easy to overlook. Over time, this damage can cause blurry vision, distorted images, or even permanent vision loss if not properly managed.
What Causes Diabetic Eye Disease?
High blood sugar is the main culprit. It damages blood vessels in the retina and triggers inflammation. Over time, this disrupts oxygen delivery to parts of your eyes and leads to abnormal vessel growth or retinal scarring.
Several risk factors can increase the likelihood of developing diabetic eye complications:
- Poor control of blood sugar levels
- High blood pressure and cholesterol
- Smoking
- Long duration of diabetes
Certain local factors can amplify these issues. In Central Pennsylvania, where access to public transportation is limited, some patients delay follow-up care. Cold, dry winters can also aggravate preexisting eye conditions, especially in people managing diabetes.
Diabetic Eye Disease Stages and Symptoms
Here’s a breakdown of the diabetic eye disease stages; knowing where you stand helps guide diabetic eye disease management and prevent severe outcomes:
1. Mild NPDR
In this earliest stage, tiny swellings called microaneurysms form in the retinal blood vessels. These changes are usually invisible to the patient, meaning there are no noticeable symptoms. However, damage is already beginning and can progress without timely care.
2. Moderate NPDR
At this point, blood vessels become more compromised. Leakage of fluid or blood into the retina increases, which may lead to slight blurring of vision. Patients often still feel functional but may struggle in dim lighting or notice subtle changes in their focus.
3. Severe NPDR
More blood vessels become blocked, limiting oxygen to parts of the retina. This increases the risk of abnormal new vessel growth. Patients may begin experiencing more significant vision fluctuations, and without close monitoring, this stage can quickly progress to vision-threatening complications.
4. Proliferative Diabetic Retinopathy (PDR)
This advanced stage is marked by the growth of fragile, abnormal blood vessels in the retina. These vessels may bleed into the vitreous or form scar tissue, which can tug at the retina and cause retinal detachment. Diabetic retinopathy can cause vision loss at a rapid and severe rate if not treated.
5. Diabetic Macular Edema (DME)
DME can occur at any point, but it is more common in advanced stages. Swelling in the macula—the part of the retina responsible for central vision—leads to blurry vision, difficulty reading, or difficulty seeing fine details. Colors may appear dull, and straight lines can look distorted.
How Diabetic Eye Disease Is Diagnosed
One of the most important steps in protecting your vision is scheduling your comprehensive eye exam. During this visit, the optometrist places special drops in your eyes to widen the pupils and get a clear view of the retina. This allows them to spot:
- Damaged or leaky blood vessels
- Swelling in the macula
- Abnormal blood vessel growth
- Scar tissue or signs of retinal detachment
At Advanced Eye Care Services, we use advanced imaging tools to track even the smallest changes over time.
Diabetic Eye Disease Treatment Options
There’s no one-size-fits-all approach to diabetic eye disease treatment, but there are effective options to preserve your vision and reduce progression:
- Laser treatment: Targets abnormal blood vessels and helps seal leaks in the retina.
- Anti-VEGF injections: Help shrink abnormal vessels and reduce swelling.
- Steroid injections or implants: Manage inflammation linked to diabetic macular edema.
These treatments are often paired with managing the underlying diabetes itself; your eye health is closely tied to your overall health.

Diabetic Eye Disease FAQs
Can diabetic eye disease be reversed?
While early stages may improve with treatment and blood sugar control, advanced damage often cannot be fully reversed. That’s why early diagnosis is so important.
How often should people with diabetes get an eye exam?
The American Diabetes Association recommends a comprehensive dilated eye exam once a year—or more frequently if you have existing eye changes.
Can high blood sugar really affect your eyes that much?
Yes. High blood sugar damages retinal blood vessels, leading to leakage, swelling, and abnormal growth that can eventually cause vision loss.
