Retinal detachment can lead to blindness

It does not hurt, but the feeling is horrible. From nowhere, the person stops seeing or even has the agonizing sensation of being with pets in their field of vision. All this because the retina, one of the inner layers of the eye, has left the place and therefore the name of the clinical picture of retinal detachment. The aazsante.fr talked to the ophthalmologist Regina Cele, who takes the main doubts on the subject. Check below:

1. What is the importance of the retina in the vision process?

Within the human eye, we have some structures arranged in layers. They follow the following order: cornea, iris, pupil, crystalline, fundus of the eye, vitro, retina, choroid and sclera (white of the eye). The ocular structures are dependent on each other, but the retina has the main role of transforming the luminous stimulus into an electrical stimulus so that the brain can perform the process of seeing. When is retinal detachment characterized?

Retinal detachment occurs when the retina detaches from the choroid, a layer that is extremely rich in blood vessels and nutrients and also plays the role of irrigating the retina. The longer the retina detaches from the choroid, the more malnourished it becomes. The retina, which is orange in color and has a flexible consistency, similar to a cellophane paper, assumes a whitish color and hardened appearance, as if it were a sheet of white paperboard. And what is the seriousness of the problem?

Retinal detachment is considered a case of ophthalmological urgency. As soon as the diagnosis is made, the patient must undergo surgery as soon as possible, because the death of the retina and, consequently, the loss of vision can occur. It is a case of urgency because there is no risk to the patient's life, but there is a life risk of the organ.

4. Are there people who are more susceptible to retinal detachment?

Detachment can occur in patients with a high degree of myopia (over ten degrees), the so-called short-sighted myopia, who have a fragile and tuned retina, are already predisposed to the problem. Diabetics are also part of the risk group because Diabetes is a type of microangiopathy, that is, it changes all the small vessels of all the organs, therefore, the irrigation of the retina is also compromised. Outside of this group, the problem is very rough whipping, such as diving, extreme sports - such as Bungee jumping - or even the impact of jumping off the ground and down, like a volleyball game. 5. What are the symptoms when there is retinal detachment?

The individual does not feel pain, but the sensation is extremely uncomfortable. There may be partial or total loss of vision (in the most serious cases) of one eye or both. Another symptom is to see a flash of extremely intense and fast light, or to go through the so-called fly-fly sensation, as if there were insects flying in your field of vision. When it happens, what should be the procedure to avoid damage?

Do not use any medicine or eye drops. Search as quickly as possible for a hospital or specialist. The prognosis of vision is stabilized depending on the speed of action to resolve the clinical picture. The longer the time to diagnose and treat, the longer the retina becomes ill and may lead to vision damage.

7. Once the surgery is performed at the appropriate time, its result is 100% guaranteed?

The result of the surgery does not just depend on putting the retina in place. As much as the anatomical part is adequate, this still is not a guarantee that the cells will function as before, that is, that the stimuli will be sent to the brain in the ideal way. The result will never be 100% positive because there are always sequels. In some cases, there may be a minimal, almost imperceptible loss of vision, while in others, what happens is that the patient sees partially, only light, only lumps, or is blinded.

Babies with Zika develop microcephaly after birth

The Centers for Disease Control and Prevention (CDC) ) of the United States reported a study of Zika-infected infants who had normal-sized heads at birth, but developed microcephaly only from five months to one year after birth. 13 children from Pernambuco and Ceará who were born with congenital Zika syndrome, identified in exams but without reduction of the skull.
