Diabetic macular edema (DME) is a condition that affects the macula, the central part of the retina responsible for sharp, central vision. DME occurs when blood vessels in the retina leak fluid and lipids into the macula, causing it to swell. This swelling can distort vision, making it difficult to see fine details, read, or drive. DME is a common complication of diabetes, especially in people who have had the condition for a long time or who have poor blood sugar control.
DME is a serious condition that can lead to vision loss if left untreated. However, early diagnosis and treatment can help to prevent vision loss and preserve sight. Treatment options for DME include laser therapy, injections of anti-VEGF medications, and surgery.
If you have diabetes, it is important to have regular eye exams to check for DME and other eye problems. Early diagnosis and treatment of DME can help to protect your vision and preserve your quality of life.

DME is a serious condition, but it can be managed with early diagnosis and treatment. If you have diabetes, it is important to have regular eye exams to check for DME and other eye problems.
Symptom
Blurred vision and distorted vision are common symptoms of diabetic macular edema (DME). DME is a condition that occurs when blood vessels in the retina leak fluid and lipids into the macula, the central part of the retina responsible for sharp, central vision. This swelling can distort vision, making it difficult to see fine details, read, or drive.
The severity of blurred vision and distorted vision can vary depending on the stage of DME. In the early stages, people may only experience mild blurring or distortion. However, as the condition progresses, vision can become more severely impaired. In some cases, people with DME may even lose their central vision.
It is important to note that blurred vision and distorted vision are not always caused by DME. Other conditions, such as cataracts, glaucoma, and macular degeneration, can also cause these symptoms. However, if you have diabetes and are experiencing blurred vision or distorted vision, it is important to see an eye doctor right away to rule out DME and other serious eye conditions.
Early diagnosis and treatment of DME is important to prevent vision loss. Treatment options for DME include laser therapy, injections of anti-VEGF medications, and surgery.
Cause
Diabetic macular edema (DME) is caused by leakage of fluid and lipids from blood vessels in the retina. The retina is the light-sensitive tissue that lines the back of the eye. It is responsible for converting light into electrical signals that are sent to the brain. The macula is the central part of the retina that is responsible for sharp, central vision.
-
Facet 1: Increased permeability of blood vessels
In DME, the blood vessels in the retina become more permeable, allowing fluid and lipids to leak out. This leakage can cause the macula to swell, which can lead to blurred vision and other vision problems.
-
Facet 2: Inflammation
Inflammation is also a contributing factor to DME. Inflammation can damage the blood vessels in the retina, making them more permeable. Inflammation can also lead to the formation of new blood vessels, which can also leak fluid and lipids.
-
Facet 3: Oxidative stress
Oxidative stress is another factor that can contribute to DME. Oxidative stress is caused by an imbalance between the production of free radicals and the body’s ability to neutralize them. Free radicals can damage the cells in the retina, including the blood vessels.
-
Facet 4: Genetic factors
Genetic factors may also play a role in the development of DME. Some people are more likely to develop DME if they have a family history of the condition.
The leakage of fluid and lipids from blood vessels in the retina is the primary cause of DME. This leakage can lead to swelling of the macula, which can cause blurred vision and other vision problems. Early diagnosis and treatment of DME is important to prevent vision loss.
Risk factor
Diabetes is a major risk factor for diabetic macular edema (DME). People with diabetes are more likely to develop DME than people without diabetes. The longer a person has diabetes, the greater their risk of developing DME. Poor blood sugar control is also a major risk factor for DME. People with diabetes who have poor blood sugar control are more likely to develop DME than people with diabetes who have good blood sugar control.
There are a number of reasons why diabetes and poor blood sugar control increase the risk of DME. First, diabetes causes damage to the blood vessels in the retina. This damage can lead to the leakage of fluid and lipids from the blood vessels into the macula. Second, poor blood sugar control can lead to inflammation in the retina. This inflammation can also damage the blood vessels and lead to the leakage of fluid and lipids.
DME is a serious condition that can lead to vision loss. Early diagnosis and treatment of DME is important to prevent vision loss. People with diabetes should have regular eye exams to check for DME and other eye problems.
There are a number of things that people with diabetes can do to reduce their risk of developing DME, including:
- Keeping their blood sugar levels under control
- Having regular eye exams
- Eating a healthy diet
- Getting regular exercise
- Quitting smoking
By following these tips, people with diabetes can reduce their risk of developing DME and protect their vision.
Diagnosis
Diabetic macular edema (DME) is a serious eye condition that can lead to vision loss. Early diagnosis and treatment of DME is important to prevent vision loss.
A comprehensive eye exam is the first step in diagnosing DME. During an eye exam, your doctor will check your visual acuity, examine your retina, and measure your intraocular pressure.
Optical coherence tomography (OCT) is a non-invasive imaging test that can provide detailed images of the retina. OCT is used to diagnose and monitor DME. OCT can show the thickness of the retina and the presence of fluid in the macula.
A combination of an eye exam and OCT is the most effective way to diagnose DME.
If you have diabetes, it is important to have regular eye exams to check for DME and other eye problems. Early diagnosis and treatment of DME can help to prevent vision loss.
Treatment
Diabetic macular edema (DME) is a serious eye condition that can lead to vision loss. Early diagnosis and treatment of DME is important to prevent vision loss. There are a number of different treatment options for DME, including laser therapy, injections of anti-VEGF medications, and surgery.
-
Laser therapy
Laser therapy is a procedure that uses a laser to seal leaking blood vessels in the retina. This can help to reduce the swelling in the macula and improve vision. Laser therapy is a common treatment for DME.
-
Injections of anti-VEGF medications
Anti-VEGF medications are drugs that block the growth of new blood vessels. These medications can be injected into the eye to help reduce the swelling in the macula and improve vision. Anti-VEGF medications are a common treatment for DME.
-
Surgery
In some cases, surgery may be necessary to treat DME. Surgery can be used to remove blood from the macula or to repair damaged blood vessels. Surgery is a less common treatment for DME, but it may be necessary in some cases.
The best treatment for DME will vary depending on the individual patient. Your doctor will work with you to determine the best course of treatment for you.
Prevention
Diabetic macular edema (DME) is a serious eye condition that can lead to vision loss. It is caused by damage to the blood vessels in the retina, which leads to leakage of fluid and blood into the macula. The macula is the central part of the retina that is responsible for sharp, central vision.
Good blood sugar control is essential for preventing DME. High blood sugar levels can damage the blood vessels in the retina, making them more likely to leak. Regular eye exams are also important for detecting DME early so that treatment can be started right away.
A study published in the journal JAMA Ophthalmology found that people with diabetes who had good blood sugar control were less likely to develop DME than people with diabetes who had poor blood sugar control. The study also found that people with diabetes who had regular eye exams were more likely to have DME detected early and treated promptly.
Preventing DME is important for preserving vision. Good blood sugar control and regular eye exams are essential for preventing this serious eye condition.
