Diabetes and its effect on eye health


The following Wednesday is marked by the "Day of Diabetes", and on this complex disease it is always good to remember some concepts for community wellbeing, especially for diabetics and how to lead a neat life for a better quality of life.

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

When the blood vessels in the eye retina (tissue sensitive to the light that connects the back of the eye) are swollen or completely obliterated or new abnormal blood vessels appear on the retinal surface. which is called diabetic retinopathy.

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

According to Centers for Disease Control and Prevention (CDC), about 90 percent of visual impairment associated with diabetes can be prevented, but early detection is the key. People with diabetes must have annual eye exams, even before they have signs of loss of vision. However, studies show that 60 percent of diabetics do not carry out tests that doctors recommend.

Something to Remember: Diabetes can cause changes in the form, even if you do not have retinopathy. If the level of blood sugar changes rapidly, it can affect the shape of the eye lens, which causes blurred vision, which returns to normal after the level of blood sugar stabilizes.

Did you know that there is a connection between diabetes and cataracts? Permanent clouding of vision due to cataract can be due to changes in the crystal product of excess blood sugar. Maintaining a good blood sugar control helps to reduce temporary episodes of temporal vision and prevent the blurred vision that would require a surgical procedure to correct that faint vision.

If you have diabetes, you have a higher risk of developing certain eye diseases, including diabetic retinopathy, glaucoma, and cataracts. The good news is that you can preserve the vision and reduce the chances of eye diseases.

Follow these steps to make sure you preserve the vision in the coming years:

1. Obtain a comprehensive eye examination with your ophthalmologist at least once a year.

In the first stage, diabetic eye disease often has no symptoms. Long-lasting eye exam allows your ophthalmologist to closely examine the retina and optical nerve for signs of damage before you notice any change in your form. Regular eye health monitoring allows your ophthalmologist to start treatment with treatment as soon as signs of illness occur.

2. Check the blood sugar

When the blood sugar level is too high, it can affect the shape of the eye lens, which causes blurred vision, which returns to normal after stabilizing blood sugar. High blood sugar levels can also damage the blood vessels in the eyes. Maintaining good blood sugar control helps to prevent these problems.

3. Maintain healthy blood pressure and cholesterol levels

High blood pressure and high cholesterol may cause eye and vision loss at increased risk of disease. Keeping under control not only helps your eyes but also overall health.

4. Quit smoking

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

5. Exercise

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

If you have diabetes, you can keep a good vision. Be sure to actively control your disease with your ophthalmologist in a way that reduces the risk of contracting any eye disease.


If you have diabetes, there are many important reasons for monitoring your doctor's diet and blood sugar control. One of these reasons is to avoid cataracts. People with diabetes are more likely to develop cataracts than non-diabetics.

Cataract is a disease in a transparent natural eye lens that becomes opaque. The light does not pass through the lens as it needs and is not adequately reflected in the retina (tissue sensitive to the light that directs the back of the eye). As a result, the vision becomes blurred, distorted or blurred. Generally, cataracts are associated with age-related changes, although other factors such as medications, surgery, exposure without control increase the level of sugar in water humor and lice; These high levels of glucose in the lenses cause it to swell, affecting the clarity of vision. The lens also has an enzyme that converts glucose into a substance called sorbitol. When sorbitol builds into a lens, it can affect cells and proteins of natural origin, making the lens less transparent and opaque. This situation eventually leads to the creation of a cataract, making the world around him mutilated, yellowish or obliterated, and increases the brightness. In the event of any doubt, from the Santiago del Estero ophthalmic society, we recommend that you always go to the Oculist for a check-up and prevent all kinds of illness.
