see an alert for possible causes of blindness and learn how to prevent it

In the health calendar, Abril Marrom is a mobilization that raises awareness about preventing and combating blindness. The measures are aimed at alerting the population to risks and diseases that could damage the eyes.

According to the Brazilian Institute of Geography and Statistics (IBGE), about 6.5 million Brazilians have symptoms of visual impairment. These major causes of blindness can occur in a variety of ways, such as ametropia (refractive errors that make it difficult to sharpen the retinal image, such as hyperopia, myopia, astigmatism, and presbyopia), glaucoma, cataracts, or even retinopathy (damage to the retina). ).

Cataracts are the leading cause of reversible blindness, and surgery restores the patient’s vision.

The Instituto de Olhos Fernando Ventura’s ophthalmologist, Catarina Ventura, warns of some possible reasons. “Ametropias occur in our daily activities and can be resolved with glasses. Another disease that has occurred relatively often due to increased life expectancy is age-related macular degeneration, ”the doctor emphasizes.

People with diabetes also need special attention, as its complications can affect vision and thus lead to blindness. Laser treatments, injections, and medications can minimize damage, but glucose balance, diet, and antidiabetic medications are key allies in improving vision.

Another common cause of blindness is glaucoma, which is considered a silent disease. “The patient does not feel any symptoms and does not notice a decrease in vision, as in cataracts. He is gradually losing his sight, his peripheral field of vision, closing the circle and leaving only a central sight, “Catarina warns. There is no cure for glaucoma, but it is under control. That is why eye care is important.

childhood blindness

In children, it is important to pay attention to eye examinations so that correctable problems can be diagnosed before causing permanent blindness.

Ophthalmologist Catarina Ventura explains the importance of regular eye examinations in these cases. “It can be congenital cataracts or congenital glaucoma. In addition to regular visits, the child also needs the parents’ attention, as the eye develops until the age of eight. So if you don’t have this routine, it is possible to miss treatment and become amblyopia. , he explains.
