What are the effects of diabetes on visual health? | Health | magazine

According to the World Health Organization (WHO), diabetes is a disease that affects 442 million adults worldwide. This means one of every 11 people.

In Ecuador, according to the latest National Health Survey (Ensanut) in 2014, 414,514 people over the age of 10 suffer from the disease.

Ana María Brutto, an expert in the Andes Ophthalmology Clinic, says that diabetes has a negative impact on vision.

"Diabetes, as a systemic pathology, affects not only the eye but also multiple organs. These vary with the damage of small vessels due to the increase in blood sugar, and also with the excess of oxidative stress and free radicals (which can affect the body's natural oxidation process, but sometimes the cells) causes direct damage to the retinal cells.


  • Shadows diminished due to diminishing visibility or vision.

  • The flare of light, this symptom is very important because it indicates that it has left the retina.

  • The vision begins to lose clarity as if each image is covered with a dark gray cloud. These points usually occur in both eyes and are a factor that indicates that hemorrhage is present.

  • Changing the visual field.

  • Another indication is that the diabetic patient reads his / her own texts as blurry and loses clarity and affects his / her central vision.

  • For patients injecting insulin, when the syringe does not progress to see the lines or numbers drawn on it, there is a factor in knowing that there is something with their visions.

  • This visual loss is very irregular, indicating that diabetics cannot easily distinguish the size of objects.

  • The difficulty they face while walking is a real danger to the patient because they cannot distinguish the distance between the road and the street. This indicator shows that visual perception of depth is reduced and it is important to visit the specialist to facilitate the patient's life.


  • The first thing that occurs when it has high glycemia (blood sugar) is cell damage due to increased oxidative stress due to excess free radicals.

  • The most common visual problem is diabetic retinopathy which is caused by damage to the retina and it affects the whole view since it is a very important tissue in the eye. Nerve cells play a key role in this process, as they help to transform light into electrical impulses that are taken by the optic nerve into the brain and interpreted as visual images. Thus, diabetic retinopathy damages small blood vessels within the retina.

  • The damage of the retina increases your risk in patients who are 50% in 10 years and 90% in the retina after 30 years.

Control of diabetic patients with visual impairment:

  • According to the expert, systemic control of an endocrinologist is sufficient, depending on the condition and the degree of participation. In other more serious cases, laser or injections should be used behind the eye to prevent vascular growth.

  • Further, a surgery is recommended when retinal detachment occurs.

  • We recommend performing periodic checks with the ophthalmologist at least once a year, including some examinations. (I) & # 39; e
