Diabetes is a medical condition that occurs when your body is unable to properly regulate blood sugar levels. It is a chronic condition that can lead to a variety of health problems, including vision problems.
In this article, we will discuss the relationship between diabetes and vision problems and what you need to know to protect your eyesight.
How Diabetes Affects Vision
When you have diabetes, your body either doesn’t produce insulin (type 1 diabetes) or doesn’t use insulin properly (type 2 diabetes). Insulin is a hormone that plays a crucial role in regulating blood sugar levels.
When blood sugar levels are consistently high, it can damage the small blood vessels in the retina, causing a condition called diabetic retinopathy.
Diabetic retinopathy is a serious eye condition that can lead to blindness if left untreated. It is the most common cause of blindness in adults with diabetes.
The condition occurs when high blood sugar levels cause damage to the delicate blood vessels in the retina, leading to swelling, leakage, and the growth of abnormal blood vessels.
Types of Diabetic Retinopathy
There are two main types of diabetic retinopathy:.
Non-Proliferative Diabetic Retinopathy (NPDR)
In this type of diabetic retinopathy, the early stage, the damaged blood vessels in the retina leak fluid or blood, causing swelling in the macula (the part of the retina responsible for central vision).
This swelling can affect your ability to see clearly and may cause distorted or blurry vision. If left untreated, the condition can progress, causing more severe damage to the blood vessels in the retina.
Proliferative Diabetic Retinopathy (PDR)
Proliferative diabetic retinopathy occurs when new blood vessels grow on the surface of the retina. These new vessels are weak and can leak blood into the vitreous (the clear gel that fills the space between the lens and the retina).
This can cause blurred vision, floaters (spots or strings that float in your vision), and even complete vision loss. In severe cases, the abnormal blood vessels can lead to the formation of scar tissue in the retina, pulling it away from the back of the eye and causing a condition called retinal detachment.
Other Vision Problems Associated with Diabetes
In addition to diabetic retinopathy, diabetes can also increase the risk of developing other eye conditions, including:.
Cataracts
Cataracts are a clouding of the lens in the eye, which can cause blurred vision and difficulty seeing in low light situations. People with diabetes are two to five times more likely to develop cataracts than those without diabetes.
Glaucoma
Glaucoma is a condition that damages the optic nerve and can lead to vision loss. People with diabetes are twice as likely to develop glaucoma than those without diabetes.
Preventing Vision Problems with Diabetes
The good news is that you can take steps to lower your risk of developing vision problems associated with diabetes. Here are some things you can do to protect your eyesight:.
Control Your Blood Sugar Levels
The most important thing you can do to prevent diabetic retinopathy and other vision problems is to keep your blood sugar levels within a healthy range.
This can be achieved by following a healthy diet, staying active, taking medication as prescribed by your doctor, and monitoring your blood sugar levels regularly.
Manage Your Blood Pressure and Cholesterol
High blood pressure and high cholesterol can also damage the blood vessels in your eyes. You can lower your risk by following a healthy diet, exercising regularly, and taking medication as prescribed by your doctor.
Get Regular Eye Exams
It is important to have regular eye exams to catch diabetic retinopathy and other eye conditions early, when they are more treatable.
Your eye doctor can perform a comprehensive dilated eye exam to check for signs of diabetic retinopathy, cataracts, glaucoma, and other eye conditions.
Quit Smoking
Smoking can increase your risk of developing diabetic retinopathy and other eye conditions. If you smoke, quit as soon as possible to lower your risk.
Treatment for Diabetic Retinopathy
If you are diagnosed with diabetic retinopathy, your treatment will depend on the severity of your condition. Treatment options may include:.
Laser Treatment
Laser treatment can be used to seal leaking blood vessels in the retina and slow the growth of new blood vessels. This can help to preserve your remaining vision and prevent further vision loss.
Injections
Injections of medication (such as anti-VEGF drugs) can be used to slow the growth of new blood vessels and reduce inflammation in the eye.
Surgery
If you have advanced diabetic retinopathy or a retinal detachment, surgery may be necessary to repair the retina and preserve your vision.
Conclusion
Diabetes is a chronic condition that can lead to a variety of health problems, including vision problems. Diabetic retinopathy is a serious eye condition that can lead to blindness if left untreated.
However, by controlling your blood sugar levels, managing your blood pressure and cholesterol, getting regular eye exams, and quitting smoking, you can take steps to protect your eyesight. If you are diagnosed with diabetic retinopathy, there are effective treatments available to slow the progression of the disease and preserve your vision.
