Diabetes is a condition with high blood sugar levels. It can harm the eyes over time. The high sugar damages the blood vessels in the eyes, causing vision problems12.
Eye diseases like diabetic retinopathy, macular edema, glaucoma, and cataracts are common in people with diabetes12. Keeping blood sugar, blood pressure, and cholesterol in check helps prevent these eye issues. Regular eye checks are also key.
Key Takeaways
- Diabetes is the leading cause of blindness in American adults.
- Diabetic retinopathy can lead to blurred or distorted vision due to macular swelling.
- Diabetes increases the risk of developing neovascular glaucoma and accelerates the progression of cataracts.
- Regular eye exams are crucial for early detection and treatment of diabetic eye diseases.
- Controlling blood sugar levels can help slow down the development of diabetic eye complications.
Introduction to Diabetic Eye Disease
Diabetic eye disease covers several eye issues linked to diabetes. These include diabetic retinopathy, diabetic macular edema, glaucoma, and cataracts3. Diabetes harms the tiny blood vessels in the eyes, causing vision problems if not treated. Early detection and managing diabetes can lower the risk of losing sight3.
What is Diabetic Eye Disease?
Diabetic eye disease is a set of eye problems that can happen in people with diabetes4. High blood sugar from diabetes damages the blood vessels in the eyes over time4. This can cause blurred vision, loss of central vision, and even blindness if not treated.
The types of diabetic eye disease include:
- Diabetic retinopathy: Damage to the blood vessels in the retina, which can lead to vision loss.
- Diabetic macular edema: Swelling of the macula, the part of the eye responsible for central vision.
- Glaucoma: Increased eye pressure that can damage the optic nerve and cause vision loss.
- Cataracts: Clouding of the eye’s lens, which can impair vision.
Keeping blood sugar levels in check, regular eye exams, and early treatment can prevent or manage these vision threats4. By understanding and tackling diabetic eye disease, people with diabetes can protect their sight and quality of life.
“Diabetic eye disease is a leading cause of vision loss in the United States, but it can be treated and prevented if caught early.”
Diabetic Retinopathy
Diabetic retinopathy is a common and serious eye problem for people with diabetes. It happens when the retina’s blood vessels change, causing leaks or new, abnormal blood vessels to grow5. Anyone with type 1 or type 2 diabetes can get diabetic retinopathy5. Those with high blood sugar, high blood pressure, high cholesterol, or diabetes for a long time are more likely to get it5.
In the early stage, diabetic retinopathy can make blood vessels weak and bulgy. If it gets worse, new blood vessels grow on the retina, causing serious vision issues5. People with diabetes over 12 years old should get their eyes checked5. If diabetic retinopathy wasn’t found in the last two check-ups, they should get checked every two years5.
Symptoms of diabetic retinopathy include getting worse vision, sudden loss of vision, seeing floaters, blurred vision, eye pain, redness, and trouble seeing in the dark56. Making lifestyle changes and getting treatment can stop it from getting worse if caught early5. Treatment options include laser treatment, eye injections, or surgery to clear out blood or scar tissue5.
A 2018 survey found many Americans didn’t know about diabetic eye diseases or how to check for them6. Hispanics and African Americans and pregnant women are more likely to get diabetic retinopathy6. People with high blood pressure and high cholesterol are also at higher risk6.
Macular Edema
Diabetic macular edema (DME) is a serious eye condition that can happen to people with diabetic retinopathy7. It makes the macula, which is key for sharp central vision, swell or thicken7. This swelling, caused by leaky blood vessels, can make vision blurry or distorted. It makes everyday tasks like reading, driving, and seeing faces hard7.
Impact on Central Vision
Macular edema often strikes those with diabetic retinopathy signs. If not treated, it can cause permanent vision loss7. This condition hits the central vision we need for daily life hard7.
But, there are treatments for diabetic macular edema8. Medicines like aflibercept, bevacizumab, faricimab-svoa, ranibizumab, dexamethasone, and fluocinolone acetonide can help8. Laser therapy and vitrectomy are also options, though they come with risks8.

Regular eye checks and managing diabetes well are key to avoiding and handling diabetic macular edema7. Keeping blood sugar, blood pressure, and cholesterol in check lowers the risk of this eye problem7. Catching it early and treating it quickly is vital for saving central vision and keeping life quality high7.
Glaucoma
Diabetes can raise the risk of getting glaucoma, which harms the optic nerve and can lead to losing vision9. About 80 million people worldwide have glaucoma, with over three million in the U.S9.. People with diabetes are twice as likely to get glaucoma than others. Over 20 years, they are 48% more likely to get open-angle glaucoma than those without diabetes9.
One type of glaucoma, neovascular glaucoma, is caused by diabetes10. This rare glaucoma type is often linked to diabetes10. High blood sugar can hurt the retina’s blood vessels. This leads to new, abnormal vessels on the iris, raising eye pressure and causing glaucoma9.
It’s key for diabetic patients to get regular eye checks to catch glaucoma early9. Keeping blood sugar under control can lower the risk of eye problems for diabetics9. There are many treatments to lower eye pressure for glaucoma patients. Surgery like laser, MIGS, or traditional methods might be needed for severe cases9.
Early eye care and managing diabetes are key to preventing and handling glaucoma for those with both conditions.
Cataracts
People with diabetes face a higher chance of getting cataracts, a clouding of the eye’s lens11. High sugar levels from diabetes can speed up cataract development by changing the eye’s lens structure11. In fact, those with diabetes might be twice as likely to get cataracts than those without12.
Cataracts are more common in older people but can strike younger if you have diabetes11. Your risk of cataracts goes up if you have diabetes for a long time, often have high blood sugar, and have macular edema11. The CDC says 32% of adults over 45 with diabetes also have cataracts12.
Signs of cataracts include cloudy or blurry vision, seeing double in one eye, and halos around lights11. To prevent cataracts, eat lots of fruits and veggies, quit smoking, wear UV sunglasses, and keep your glucose levels in check11.
For cataracts, surgery is usually the go-to, replacing the cloudy lens with an artificial one11. This surgery is usually done as an outpatient or in a hospital, taking about 10 minutes, followed by several hours of recovery11. The National Eye Institute says 90% of people see better after surgery12.

After surgery, you might need eye drops, avoid rubbing your eye, and wear protective glasses for a few weeks to fully recover11. Rarely, surgery can have complications, so it’s key to talk to an eye doctor about your options11.
| Key Findings | Source |
|---|---|
| Cataracts are common in the aging population but can also occur at a younger age when an individual has diabetes. | 11 |
| High blood sugar levels from diabetes can accelerate the development of cataracts due to structural changes in the lens of the eye. | 11 |
| People with diabetes are at a greater risk of developing cataracts based on the duration of diabetes, frequency of high glucose levels, and presence of macular edema. | 11 |
| Symptoms of cataracts include cloudy or blurry vision, double vision in one eye, halos around lights, light sensitivity, night vision difficulties, and faded colors. | 11 |
| People with diabetes may be twice as likely to develop cataracts as those without diabetes. | 12 |
| 32% of adults aged 45 and over who have diabetes also have cataracts, according to the Centers for Disease Control and Prevention (CDC). | 12 |
| 90% of people can see better after having cataract surgery, according to the National Eye Institute. | 12 |
In summary, diabetic cataracts are a big concern for those with diabetes. High sugar levels can make cataracts develop faster, and people with diabetes are at higher risk. Knowing about symptoms, prevention, and treatment is key to keeping your eyes healthy and your vision clear.
diabetes affect the eyes
Diabetes can harm eye health by damaging small blood vessels in the body, including those in the eyes5. High blood sugar levels can weaken these vessels, causing eye problems.
Diabetic retinopathy is a main issue caused by high blood sugar5. If not treated, it can lead to blindness5. This condition has three stages: background, pre-proliferative, and proliferative retinopathy5.
Some things increase the risk of diabetic eye problems, like poor blood sugar control, high blood pressure, high cholesterol, and smoking5. People like African Americans, American Indians, Hispanics/Latinos, and older adults face a higher risk of losing vision to diabetes5.
| Risk Factor | Impact on Diabetic Eye Disease |
|---|---|
| Long-standing diabetes | 5 Increases the risk of developing diabetic retinopathy. |
| High blood sugar level | 5 Can lead to the development and progression of diabetic retinopathy. |
| High blood pressure | 5 Increases the risk of diabetic eye problems. |
| High cholesterol | 5 Contributes to the development of diabetic eye disease. |
| Smoking | 5 Raises the risk of diabetic eye complications. |
| Ethnicity | 5 African Americans, American Indians, and Hispanics/Latinos are at greater risk of vision loss from diabetes. |
People with diabetes should take steps to manage their condition and watch their eye health5. Regular eye checks, treating eye problems quickly, and living a healthy life can lower the risk of diabetic eye disease5.
Symptoms and Early Detection
In the early stages of diabetic eye disease, there may be no noticeable13 symptoms. Vision may stay clear until the disease gets worse. But, you might see blurry or wavy vision, changes in vision from day to day, dark areas or vision loss, poor color vision, and more floaters or flashes of light13.

Regular eye exams are key for catching diabetic eye problems early. They help eye doctors spot issues before vision loss gets worse13. Dilated eye exams, where eye drops make the pupils bigger, are especially useful for finding diabetic retinopathy and other conditions13.
Retinopathy is the main reason for vision loss in adults in their working years14. About half of people with diabetic retinopathy get macular edema14. Catching eye diseases early can stop permanent vision loss14.
Diabetes also raises the risk of open-angle glaucoma, and neovascular glaucoma can happen from diabetic retinopathy14. Swelling in the macula from diabetic macular edema can make vision blurry14. And, cataracts might come earlier in life if blood sugar isn’t well-controlled14.
By getting regular eye exams, people with diabetes can spot and manage eye problems early. This helps keep their vision good and prevents long-term damage13.
Prevention and Management
To prevent or delay diabetic eye disease, managing diabetes well is key. This means keeping blood sugar levels in check, controlling blood pressure and cholesterol, and stopping smoking15. Keeping the “diabetes ABCs” under control can greatly lower the risk of eye problems or slow down existing ones15. Also, protecting your eyes from UV rays and eating a healthy diet can boost your eye health.
Controlling Blood Sugar and Other Factors
For diabetics, managing blood sugar, blood pressure, and cholesterol is crucial to avoid eye disease15. Studies prove that keeping these levels in check can reduce eye disease and vision loss risks15. Catching diabetic retinopathy early and treating it can stop most people from going blind15.
Some groups face a higher risk of diabetic eye disease, like African Americans, Hispanics/Latinos, or American Indians/Alaska Natives15. Those with a family history of glaucoma, over 60, or certain ethnic groups are also at greater risk15. Getting regular eye exams is key to spotting these eye diseases early in diabetics15.
| Diabetes-Related Eye Conditions | Risk Factors |
|---|---|
| Diabetic Retinopathy | Type 1, type 2, or gestational diabetes15 African Americans, Hispanics/Latinos, or American Indians/Alaska Natives15 |
| Glaucoma | Family history of glaucoma15 Age 60 and older15 Specific ethnic groups15 |
| Cataracts | Diabetes15 |
By actively managing diabetes and focusing on eye health, diabetics can greatly lower their risk of vision loss151617.
“More than 90% of diabetes-related vision loss can be avoided with early detection and treatment.”16
Treatment Options
Doctors may suggest different treatments for diabetic eye disease based on its severity18. For mild cases, anti-VEGF injections can be used to stop abnormal blood vessels from growing and reduce fluid leakage19. Laser treatments can also help by sealing off leaking blood vessels or destroying bad ones18. For severe cases, surgery like vitrectomy might be needed to clear out blood or scar tissue from the eye19. The best treatment plan depends on the person’s condition and how far the eye disease has progressed.

Anti-VEGF injections might cause some discomfort, like burning or pain, for a day or two after18. Laser treatments can make vision blurry for a day too18. While new treatments show promise, we need more studies to know how well they work and if they’re safe18. Researchers are testing new ways to treat diabetic retinopathy18.
Spotting and treating diabetic eye disease early is key to saving vision and avoiding more problems19. By working with a healthcare team, people with diabetes can get the right treatment for their eyes and improve their overall health. This can lower the chance of losing sight19.
| Treatment Option | Mechanism of Action | Potential Side Effects |
|---|---|---|
| Anti-VEGF Medications | Block the growth of abnormal blood vessels and reduce fluid leakage | Mild discomfort (burning, tearing, or pain) for up to 24 hours after injection |
| Laser Treatments | Seal leaking blood vessels or destroy abnormal vessels | Blurred vision for about a day after the procedure |
| Vitrectomy Surgery | Remove blood or scar tissue from the eye | Risks associated with any surgical procedure |
The right treatment for diabetic eye disease depends on the person’s condition and how bad the eye disease is19. Regular eye check-ups and quick action are key to keeping vision good and preventing more eye problems19.
“Proper management of diabetic eye disease is essential for maintaining good vision and quality of life.”
By following advice from healthcare providers and sticking to treatment plans, people with diabetes can help manage their eye health. This can lower the risk of losing vision19.
Conclusion
Diabetes can seriously affect eye health, leading to vision-threatening conditions like diabetic retinopathy, macular edema, glaucoma, and cataracts20. But, by managing diabetes well and getting regular eye exams, people with diabetes can lower their risk of these eye problems. This helps them keep their vision20.
It’s key to get regular eye exams because many diabetic eye issues don’t show symptoms early on20. Keeping blood sugar, blood pressure, and cholesterol in check is vital to stop eye problems from coming back and to keep vision healthy20. With the right treatments like lasers, injections, surgery, and eye drops, people with diabetes can protect their sight and cut down the risk of losing vision20.
This summary highlights the main points about how diabetes affects eye health, the need for regular eye exams, and the importance of managing diabetes to prevent vision issues2021. Now, readers know how crucial eye health is and how managing diabetes can protect their vision and improve their life quality.
