Several people suffer from diabetes, but aside from the condition alone, it may also lead to further complications. Among them is how it could eventually affect one’s vision. Read on to know more about the types and stages of diabetic retinopathy.
As the name suggests, diabetic retinopathy refers to an eye condition due to diabetes. This complication weakens the blood vessels in the retina (thin light-sensitive tissue layer in the back of your eyes).
Most people have no symptoms of diabetic retinopathy in the early phases. You may not notice any changes in your vision until the condition worsens. Symptoms may appear and disappear for some people. Some of the notable symptoms include:
Diabetic retinopathy is more likely to develop as your diabetes progresses over time. This, in turn, affects both eyes.
When you have high blood sugar levels for an extended period of time, fluid can build up in the lens inside the eye, which controls focusing. This alters the curvature of the lens, resulting in vision changes. But, when blood sugar levels are under control, the lens will usually return to its original shape. Hence, improving your vision. Those who can better control their blood glucose levels will have a slower onset and progression of the eye condition.
Similar to any other disease, diabetic retinopathy also has some particular types.
This type refers to the early disease stage wherein blood vessels swell and leak. It may appear as a fluid, hemorrhage, or lipid in the retina. These blood vessels eventually close, resulting in ischemia, or low blood flow. In some cases, it can also lead to macular edema (retinal swelling), which can lead to mild vision loss.
As the disease advances, the abnormal blood vessels tend to develop as a reaction to ischemia. These vessels can rupture and leak into the clear watery gel, which fills the eye. Thus, resulting in severe vision loss.
A person with this condition may also have other serious eye conditions like diabetic macular edema and neovascular glaucoma.
Diabetic retinopathy is an eye condition that can manifest f in different stages as it progresses. Your eye doctor may conduct several tests with a complete health history and eye exam to diagnose it. A visual acuity test is a common eye chart test measuring the central vision ability at different distances.
In this stage, there are tiny bulges (microaneurysms) that have formed in the blood vessels of the retina. This then allows small amounts of blood to leak, which is quite common to people with diabetes.
During this stage:
The second stage puts your eyes, particularly your retina, to severe and widespread changes. Bleeding into the retina may also take place.
At this stage:
Upon reaching the third stage, there is the formation of new blood vessels and scar tissues on the retina. Thus, causing massive bleeding which may lead to retinal detachment. This is a condition wherein the retina pulls away from the back of the eye.
At this stage:
There are those instances wherein the blood vessels in the central part of the retina (macula) could become leaky or blocked.
If the doctor discovers this in your eyes:
The treatment for diabetic retinopathy varies according to the severity of the disease. Some may require laser surgery to seal leaking blood vessels or to prevent other blood vessels from leaking. An optometrist may also need to inject medications into the eye to reduce the inflammation or stop the formation of new blood vessels. But those with advanced type may need more than these two common treatments. They may undergo a surgical operation, such as a vitrectomy, to remove and replace the vitreous, gel-like fluid in the retina. A retinal detachment may also demand eye surgery.
If you have diabetes, you can help minimize or slow down the progression of diabetic retinopathy by doing the following:
Although preventing diabetic retinopathy can be difficult, there are still ways to reduce the chances of it worsening.
Getting a diabetic eye exam at least once a year and following your diabetes management plan are helpful steps to keep things at bay.
