Glaucoma and diabetes can lead to blindness; know more

Glaucoma e diabetes are silent diseases that, if left untreated, can lead to blindness. To combat these evils through information, the campaign was created brown Aprilan alert to the Brazilian population about problems that can lead to irreversible loss of vision and that can be avoided.

Understand how these diseases affect vision and how it is possible to prevent its progression.

According to the World Health Organization (WHO), 80% of the causes of eye diseases can be prevented or treated. The entity’s 2019 world report on vision states that at least 2.2 billion people are visually impaired or blindness not world.

EyesAbril Marrom campaign was created to encourage eye care

The number of carriers of Visual impairment that could have their cases avoided is at least 1 billion people.

In Brazil, 6.5 million people are visually impaired, according to the Brazilian Institute of Geography and Statistics (IBGE). According to data released by the Brazilian Council of Ophthalmology (CBO), 1.577 million of them (0.75% of the population) are blind. Of these, 74.8% of the cases could have been prevented or cured.

causes of blindness

According to Fernando Malerbi, coordinator of the Brazilian Society of Diabetes (SBD) and member of the Brazilian Society of Retina and Vitreolus (SBRV), in an interview about Abril Marrom with Agência Brasil, the main causes of blindness in adults are age-related macular degeneration. (AMD), the waterfallglaucoma and diabetes.

Age-related macular degeneration affects the elderly after age 60 in two ways: dry or wet. In the dry form, the treatment is a compound of vitamins that delays the evolution: in the wet form, the treatment is done with the injection of drugs through the intraocular route.

Cataract, characterized by blurred vision, can be treated by surgery, according to Malerbi, while glaucoma and diabetes have different characteristics and need prevention.

Find out below the causes of preventable diseases to understand how it is possible to prevent and treat them before symptoms worsen.


The disease arises when the optic nerve begins to show damage. Visual information fails to correctly travel between the eye and the brain in a gradual, slow and imperceptible way. But, despite being silent, after considerable damage, “blind spots” appear in the vision.

OphthalmologistRegular visits to the ophthalmologist help prevent the onset of diseases that lead to blindness

Regular visits to the ophthalmologist – at least once a year – can identify the problem and get the patient started on treatment to prevent disease progression. Otherwise, over time, the entire optic nerve is destroyed and blindness occurs, which can lead to complete loss of vision due to increased intraocular pressure.

the treatment of glaucoma it is done through exercises to reduce the internal pressure of the eyes and through the regular use – even when the patient is without symptoms – of specific eye drops.


A rdiabetic etinopathy (RD) is caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). The condition can develop in anyone who has type 1 or type 2 diabetes and occurs when the disease is not controlled.

Asymptomatic at first, DR only presents with sudden, painless visual changes in advanced stages. To avoid it, it is necessary to perform retinal mapping periodically with an ophthalmologist and maintain the diabetes under control.

Treatment with drugs or surgical procedures prevents the progression of the condition and, therefore, early diagnosis is essential to prevent loss of vision.

Brown April Campaign

The initiative is carried out jointly by the Brazilian Retina and Vitreous (SBRV) and Diabetes (SBD) societies and takes the color brown in the name because this is the shade of the iris (the most visible color of the eyes) of most Brazilians.

To prevent vision loss, see an eye doctor regularly.
