Do you have diabetes? Or does someone you know have diabetes? Then what I'm about to say is very important to you. Diabetes is a disease in which the blood sugar level in the body increases. This can cause damage to our eyes in unexpected ways. That damage is called `(Diabetes-Related Retinopathy)` or diabetes-related retinal disease. Let's talk about this in detail today, okay?
What is Diabetes-Related Retinopathy?
Simply put, `(Diabetes-Related Retinopathy)` means that diabetes weakens and damages the blood vessels in the retina inside your eyes. Think of it like a camera. The retina works like the film in this camera. It is here that images are recognized when light falls. So, when these small vessels that supply blood to the retina are damaged due to diabetes, the retina also stops working properly. This can lead to decreased vision, blurred vision, and eventually, even blindness .
Not everyone with diabetes will get this condition. And, there are things we can do to delay its onset, or even reduce its impact if it does. So don't be afraid, okay? Let's talk about that too.
There are two stages of this disease.
`(Diabetes-Related Retinopathy)` does not get worse all at once. It has two main stages.
1. Early stage: Nonproliferative diabetes-related retinopathy (NPDR)
This is the early stage of the disease. During this stage, blood vessels in the retina begin to leak blood. Think of it like a broken water pipe. This damage can cause some of the blood vessels to become blocked. This happens as the body tries to repair the damage. You may not have any major symptoms at this stage.
2. Severe case: Proliferative diabetes-related retinopathy (PDR)
NPDR progresses to the stage called PDR when the damaged blood vessels become more severe. This is when new, but weaker, blood vessels begin to form in place of the damaged ones. These new vessels are formed in an attempt to increase blood flow to the retina. However, these new vessels are very weak and can easily burst and bleed. This blood can collect in the jelly-like substance inside the eye called the vitreous. Since these new vessels form on the surface of the retina, over time the jelly can stick to these vessels and the retina can detach (retinal detachments) . If this happens, the chances of blindness are high.
What are the symptoms of this disease?
In the early stages of Diabetes-Related Retinopathy, you may not notice any symptoms. That's the scary part. You may not notice any changes in your vision until the damage is more extensive. However, once symptoms start to appear, they can include:
- Blurred or distorted vision: It feels like you're looking through a fog, or things seem to be stretched out.
- Changes in color perception: Colors that were previously clearly visible may now appear faded or less vivid. You may even develop new color blindness.
- Night blindness (nyctalopia): Vision is greatly reduced at night.
- Eye floaters (myodesopsias): The sensation of seeing small black dots or threads floating in front of the eyes.
- Blind spots (scotomas): Some parts of what you see are invisible.
- Visual field defects: The amount of vision in the surrounding area is reduced.
- Weakening of vision and eventual loss of vision.
If you have any of these symptoms, you should see an ophthalmologist immediately .
Why does this situation occur?
The main cause is diabetes . This condition can be caused by different types of diabetes.
- Type 1 diabetes `(Type 1 diabetes)`
- Type 2 diabetes `(Type 2 diabetes)`
- Type 3c diabetes `(Type 3c diabetes)`
- Gestational diabetes
Diabetes is a condition that starts when your blood sugar levels stay high for a long time . When this sugar builds up, it damages the inner walls of blood vessels throughout your body. It also affects the delicate blood vessels in your eyes.
Damaged blood vessels try to repair themselves and find other ways to keep blood flowing. As a result, those weak, new blood vessels that I mentioned earlier form on the surface of the retina. These can easily burst and bleed into the jelly-like substance inside the eye (vitreous). Also, fluid can leak from the damaged blood vessels and cause the central part of the retina, the part where we see clearly and distinguish colors (macula), to swell. This is called macular edema . Then, vision becomes blurry.
What are the risk factors?
There are several other risk factors that can affect the development of `(Diabetes-Related Retinopathy)`.
- Diabetes that is difficult to control: The risk is higher if blood sugar levels are consistently high.
- High blood pressure (hypertension)
- High cholesterol level in the blood (hyperlipidemia)
- Heart-related diseases such as heart disease and coronary artery disease
- Chronic kidney disease and kidney failure
If these conditions are present, the risk of eye damage increases even more when combined with diabetes.
Possible complications of this disease
If Diabetes-Related Retinopathy is not properly controlled, further complications can occur.
- Diabetes-related macular edema (swelling in the center of the retina caused by diabetes)
- Retinal detachments
- Bleeding into the jelly-like part of the eye (vitreous hemorrhage)
- Glaucoma (increased eye pressure)
- Reduced blood supply to the part of the retina that provides color and sharp vision (macular ischemia)
Eventually, these complications can cause the light-detecting cells inside the eye, called photoreceptors, to stop working properly. This can lead to permanent vision loss and blindness.
How is this disease diagnosed?
As I said before, many changes in the eye caused by `(Diabetes-Related Retinopathy)` do not show symptoms in the early stages. However, an ophthalmologist can detect these changes very early. This is done by using special equipment and using medicine to dilate the eye. This is also called `(dilated eye exam)` .
During this exam, the doctor may see things like:
- Cotton wool spots inside the eye
- Retinal hemorrhages
- Small blood vessels that are swollen and burst (microaneurysms)
- Neovascularization of the eye (new blood vessels forming inside the eye)
- Swelling of the central part of the retina (macular edema)
- Fatty deposits in the retina (retinal exudates)
- Abnormal-looking blood vessels in the retina
- Bleeding into the jelly-like substance inside the eye (vitreous hemorrhage)
Therefore, if you have diabetes, even if you don't have any symptoms, it's very important to have your eyes checked by an ophthalmologist at least once a year.
How is `(Diabetes-Related Retinopathy)` treated?
This is the most important part. `(Diabetes-Related Retinopathy)` is a condition that can be treated, but it cannot be completely cured . Some of the symptoms and changes in the retina can be treated. However, once the damage is too severe, some things cannot be reversed.
There are two main treatment options: controlling your diabetes and treating your eyes.
1. Managing your diabetes
Research has clearly shown that the higher your blood sugar level and hemoglobin A1C, the higher your risk of developing Diabetes-Related Retinopathy . Therefore, controlling your blood sugar levels – meaning keeping them low and stable – is very important to delay the onset of this disease and reduce its severity.
To control diabetes, you must do these things:
- Check your blood sugar levels regularly: This can be done with finger-stick testing or continuous glucose monitoring.
- Be mindful of what you eat: What you eat directly affects your blood sugar levels and A1C values.
- Taking your prescribed medications correctly: Take your diabetes medication exactly as your doctor tells you to. This will go a long way in keeping your blood sugar levels within the recommended range.
- Going for regular check-ups: This is very important to know about your general health. You can identify changes even before symptoms appear.
- Getting regular eye exams as recommended: This is essential if you have diabetes or prediabetes. Treatment can begin before damage becomes permanent.
- Maintaining a healthy weight that suits you: This also helps control diabetes. Your family doctor will guide you on this.
2. Eye treatments
The goal of eye treatment is to control vision and eye symptoms and limit or reduce damage to the retina. Some specific treatments for Diabetes-Related Retinopathy include:
- Medications: For example, anti-vascular endothelial growth factor (anti-VEGF) drugs or corticosteroids are used. These are injected into the eye. Your eye doctor will explain other medication options.
- Laser surgery: In procedures such as laser photocoagulation , an eye specialist uses a laser to treat your retina. This can stop the growth of new, abnormal blood vessels, shrink them, or stop the blood from leaking. However, this can sometimes cause some loss of night vision or peripheral vision.
- Eye surgeries: If your retina has become detached (retinal detachment), if blood has collected inside the eye (vitreous hemorrhage) and it won't drain, or if there is other severe damage to the retina, your doctor may recommend a surgery called a vitrectomy .
When should I see my doctor?
If you have diabetes, or have been diagnosed with Diabetes-Related Retinopathy, it is very important to see an eye specialist regularly. He/she will tell you how often you should come in for checkups. Following this schedule can help you identify any serious changes before they become severe.
Also, see a doctor immediately if you notice any of the following gradual vision changes :
- Decreased vision or not seeing as well as before.
- Blurred or distorted vision.
- If some parts of the things you are looking at are dark, faded, or look different than they did before.
However, if you experience sudden vision changes like these, you should go to the nearest hospital or emergency room immediately:
- Severe eye pain.
- Sudden complete loss of vision or severe vision loss.
What kind of future can someone with `(Diabetes-Related Retinopathy)` expect?
Diabetes-Related Retinopathy is a permanent, lifelong condition. There is no cure for it. However, you can take steps to control it and limit vision loss.
People with diabetes are more likely to develop this condition, but not everyone with diabetes will develop it. However, it can have a major impact on your life, so it's important to do everything you can to prevent or delay it.
If you detect the disease early and get treatment on time, you can prevent vision loss and delay the progression of the disease. Even after treatment, if you control your diabetes well and keep your blood sugar levels within the levels recommended by your doctors, you have the best chance of limiting the effects of this disease.
Unfortunately, some people can develop serious complications. However, there are ways to delay those complications as much as possible and manage vision changes caused by diabetes.
Can Diabetes-Related Retinopathy be prevented?
Yes, controlling your blood sugar levels and maintaining a low hemoglobin A1C level can help prevent Diabetes-Related Retinopathy. When you do these things, the retinopathy can sometimes regress.
Not everyone with diabetes has this, but those with uncontrolled blood sugar levels and those with diabetes for a long time are significantly more likely to develop ``Diabetes-Related Retinopathy''.
Even if you don't have diabetes, if you are at high risk of developing it (for example, if you have prediabetes), you can take action before you are diagnosed with diabetes. Taking action early can prevent or delay the development of diabetes. It can also affect the development of diabetes-related retinopathy.
Eye exams can help you identify early signs of Diabetes-Related Retinopathy long before you experience symptoms. If someone in your family, especially your parents, siblings, or children, has diabetes, you are at higher risk of developing it too. That's why it's important to have regular eye exams.
No matter how well you control your diabetes, sometimes it may not be enough to prevent the development of ``Diabetes-Related Retinopathy''. However, controlling your diabetes, getting regular eye exams, and taking care of your eyes are still very important. They can help protect your vision.
Your diabetes doctor can guide you on this and refer you to an eye specialist. With regular care and support, there are many things you can do to protect your precious vision.
The most important things to remember (Take-Home Message)
Okay, so here are some things you need to remember from what we've talked about:
- If you have diabetes, take special care of your eyes. Diabetes-Related Retinopathy can be a serious condition.
- Keep your blood sugar and ``Hemoglobin A1C`` levels under control. This is the most important thing.
- Even if you don't have any symptoms, you should definitely have your eyes checked by an ophthalmologist at least once a year (dilated eye exam). Early detection is easier to treat.
- If you notice any changes in your vision (blurring, black spots, discoloration), see a doctor immediately.
- If you smoke, stop. Smoking can also worsen this condition.
- Control things like high blood pressure and cholesterol.
Remember, you are not alone. There are doctors and family members who can help you. If you don't panic, get the right treatment, and live a healthy lifestyle, you can protect your eyes.
