Diabetes and its effects on eye health


Next Wednesday marks the "Diabetes Day", and about this complicated disease, it's always good to remember some concepts for the benefit of the community, especially for diabetics and how to live a regular life for a better quality of life.

Diabetes is a disease that affects the body's ability to produce or use insulin efficiently to control blood sugar levels. Although glucose is an important energy source for body cells, excess glucose in the blood for a long time can cause damage to many parts of the body, including the heart, kidneys, blood vessels and small blood vessels. from the eye.

When blood vessels in the retina of the eye (light sensitive tissue that lines the back of the eye) swell or close completely, or if new abnormal blood vessels grow on the surface of the retina, it appears. called diabetic retinopathy.

People who are most at risk of developing diabetic retinopathy are those who have diabetes or poor blood sugar control, pregnant women and people with high blood pressure, high blood lipids or both. The risk also increases with the duration of diabetes. For example, a woman develops diabetic retinopathy after living with diabetes for approximately 25 years. In addition, people from certain ethnic groups, such as African-Americans, Hispanics and Native Americans, are more likely to develop diabetic retinopathy. In fact, a new study confirms that diabetes is a higher percentage risk factor for vision loss among Hispanics.

According to the Centers for Disease Control and Prevention (CDC), about 90 percent of vision associated with diabetes can be prevented, but early detection is the key. Diabetics must undergo an annual eye examination, even before they have signs of loss of vision. However, research shows that sixty percent of diabetics do not take the tests their doctors recommend.

Something to remember: Diabetes can cause changes in vision, even if you don't have retinopathy. If your blood sugar levels change rapidly, it can affect the shape of the lens of the eye, causing blurred vision, which returns to normal after stable blood sugar levels.

Did you know that there is also a connection between diabetes and cataracts? Permanent blurring of vision due to cataracts may also be a result of changes in excess blood sugar crystal products. Maintaining good control of your blood sugar helps reduce episodes of transient blurred vision and prevents turbidity that requires surgery to correct the poor vision.

If you have diabetes, you are at a higher risk of certain eye diseases, including diabetic retinopathy, glaucoma and cataracts. The good news is that you can maintain your vision and reduce the possibility of eye disease.

Follow these steps now to make sure you maintain your vision for years to come:

1. Get a comprehensive eye exam with your eye doctor at least once a year.

In the first stage, diabetic eye disease often has no symptoms. Widespread eye examination allows your ophthalmologist to examine the retina and optic nerve more closely for signs of damage before you see changes in your vision. Regularly, monitoring your eye health allows your ophthalmologist to start treatment as soon as possible if signs of disease appear.

2. Control blood sugar

When blood sugar levels are too high, it can affect the shape of the eyepiece, causing blurred vision, which returns to normal after your blood sugar is stable. High levels of sugar in the blood can also damage the blood vessels of the eye. Maintaining your blood sugar control well helps prevent this problem.

3. Maintain healthy blood pressure and cholesterol levels

High blood pressure and high cholesterol can make your eyes and eyesight lose a higher risk of disease. Keeping it under control will not only help your eyes, but also your overall health.

4. Stop smoking

If you smoke, the risk of diabetic retinopathy and other eye diseases associated with diabetes is higher. Termination of tobacco will help reduce that risk.

5. Exercise

Exercise is good for the eyes. This is also good for your diabetes. Regular exercise can help keep your eyes healthy as possible while helping to control diabetes.

If you have diabetes, you can maintain a good vision. Be sure to actively control your illness with your eye doctor in a way that reduces the risk of aggravating eye disease.


If you have diabetes, there are many important reasons to follow your doctor's instructions about diet and blood sugar control. One reason: avoid cataracts. People with diabetes are more likely to develop cataracts than non-diabetics.

Cataracts are diseases of the natural lens transparent eyes that become opaque. Light does not pass through the lens properly and is not sufficiently reflected in the retina (light-sensitive tissue that lines the back of the eye). As a result, vision becomes cloudy, distorted or blurred. In general, cataracts are associated with age-related changes in the eye, although other factors, such as drugs, surgery, exposure without control), increase sugar levels in aqueous humor and in the lens; The high level of glucose in the lens causes it to swell, which affects visual clarity. The lens also has an enzyme that converts glucose into a substance called sorbitol. When sorbitol forms in the lens, it can affect cells and proteins that come from nature, making the lens less transparent and more opaque. This condition eventually leads to cataract formation, making the world around them appear blurred, yellowish or discolored, and increasing brightness. If there are doubts, from the Ophthalmological Society of Santiago del Estero, we recommend that you always go to Oculist for control checks and to prevent all types of diseases.
