The eyes are, perhaps, those parts of the body that until they begin to cause problems, whether due to tired eyesight, styes,

or loss of vision, to give just one example, we do not begin to pay attention to them.

And how important, if not essential, they are.

Even more so, when you dedicate yourself to a "risk profession" such as

.

If not, let them tell the young rider Marc Márquez.

He knows more than well what it is to value something as simple (for the lucky, non-myopic) as seeing correctly without any kind of effort, help or problem.

And this is the second time that the ilerdense has diplopia, or as it is more commonly known, double vision.

It was

when the motorcyclist suffered this symptomatology for the first time, which would evolve into the most serious injury of his entire career.

It was October 21, 2011 and in '93, one of its main identity marks,

.

During training sessions in Malaysia, the now eight-time motorcycling world champion suffered a serious accident, and that's when everything went wrong.

Almost a decade later and when he was recovering from the discomfort in his right arm as a result of the fracture that occurred in the humerus in Jerez 2020 and the

, the main pathology of this article, diplopia, has been reproduced in the Catalan .

But what exactly is this condition that brings the twenty-somethings head over heels in?

"Basically what this visual disorder consists of is that our brain perceives a double image. So our first sensations are that we see a duplicate image", explains Dr. Fernando Cabrera, neurologist and

of the Spanish Society of Neurology (SEN). And is there a specific factor or reason that causes this problem?

The

, head of the Unit of Neuro-ophthalmology at the Hospital Clinic in Barcelona, responds: "There are many causes of injury or diplopia From simple alterations as small strabismus, injuries of nerves that move the eyes.. Or sometimes it is for something that injures these nerves, but for another cause not proper to the nerves, but external to them ".

So the prognosis depends more on the factor that triggers the

than on the condition itself? "Yes, for example head injuries of mild or moderate intensity have a double vision associated with this and usually have a more or less benign course, around 80% recovery. So, diplopia itself can be something that indicates a symptom of great severity, as in the case of cerebral infarcts, or of little, depending on the cause ", indicates the expert of the SEN.

Precisely a

was the cause of the evil, both current and previous, of Marc Márquez from Cervantes.

This is corroborated by this press release signed by his doctor: "The examination carried out on Marc Márquez after the trauma that occurred, has confirmed that the pilot has diplopia and has revealed a paralysis of the right fourth nerve with involvement of the superior oblique muscle right. This nerve is the one that was already injured in 2011. "

Even so, to reverse this problem, they have opted "to carry out a conservative treatment with periodic controls to follow the clinical evolution", unlike ten years ago, when they decided to

.

Option that is not ruled out at present if the prognosis does not improve.

And it is that the

to eradicate this problem also depends on several factors: "It depends on the cause that triggers it, on what this diplopia is like, because there are several types, and on the evolution itself", highlights the physician Sánchez Dalmau.

Likewise, the two doctors coincide in highlighting the importance of prior diagnosis.

Different types of visual disorders

Drop down

Apart from this double vision disorder, there are more visual conditions.

These can be hereditary,

or even caused by external factors such as trauma.

Mainly they can be classified into three types according to the effects they cause on vision: Disorders that cause a decrease in visual acuity, others that lead to

, and some that are manifested by a distorted perception of objects, in addition to that cause double vision, where only diplopia is found.

Thus, some examples of the most frequent pathologies that alter vision are these: Horton's disease, the

which

;

retinal detachments, which cause blurred vision;

or ophthalmic migraine, in which lack of sleep would play a relevant role in activating the disease.
