An old known symptom of Spanish has manifested itself again. We tell you what the diplopia that Marc Márquez has been diagnosed with is about.
The news that Marc Márquez has diplopia has been repeated several times in the life and professional career of the motorcyclist. This time, after the accident suffered in Mandalika while tests of the motorcycle gphis condition has recurred.
As far as we know, Marquez has been dealing with this problem for quite some time. And every time a head injury intervenes, the diplopia reappears. But we are not dealing with minor injuries, but with truly serious impacts that even put life at risk.
What is in the background is a paralysis of the fourth cranial nerve on the right side, which modifies the functioning of the superior oblique muscle on the same side. Therefore, the eyeballs cannot fit well and double vision appears.
What is diplopia?
Marc Márquez’s diplopia is the duplicated visual perception of an object that is unique. In simple terms, we talk about double vision.
It is likely that we have experienced it at some time, but temporarily. However, the disorder can be configured as a more chronic and persistent clinical picture, associated with vision pathologies, but also with neurological alterations.
There are two great guys of diplopia:
- Monocular: appears with only one eye open.
- Binocular: it is only evident with both eyes open and stops when one of the eyelids closes.
Causes
Since monocular and binocular diplopia are not the same, the etiologies also change. That is, the causes of each can be distinguished.
Cataracts, keratoconus and astigmatism are the most frequent origins of the monocular variant. all these conditions they have in common the alteration of the passage of light towards the retina. Therefore, the rays fail to hit the back of the eye, where they should correctly stimulate the receptors.
On the other hand, binocular diplopia is frequently caused by myasthenia. gravis and to palsy of the oculomotor cranial nerves. These are the ones named with the Roman numerals III, IV and VI. Justly, Marc Márquez has a paralysis of number IV right now.
Marc Márquez’s history of diplopia
As we already anticipated, It is not the first time that Marc Márquez suffers from diplopia. Actually, according to what we have records, it is the fourth.
The beginning was in his youth, while he was competing in the Spanish Speed Championship. A head injury led to compression of certain eye muscles that did not allow correct accommodation. However, since it was an inflammatory condition, he quickly improved.
Some time later, in 2011, he had an accident again and the accumulation of liquid around the orbit caused the diplopia to recur. He was approached expectantly, so spontaneous recovery was expected, but that did not happen and it was found that there was fourth cranial nerve palsy. So at the beginning of 2012 a surgical approach was chosen.
Marc Márquez’s third diplopia was in October 2021 after an accident in training. At the time there were no major inconveniences, however, later the symptom manifested and his primary ophthalmologist confirmed it. Again, there was nerve paralysis. He did not require surgery and recovered spontaneously. Until now.
In this last report after the accident in the motorcycle gphis doctor stated that there is diplopia, possibly as a recurrence of the one in 2021. Less serious, although related to the same paralysis of the oculomotor nerve. For now, there will be no surgery. Follow-up will be done to define the therapeutic conduct.
What awaits Marc Marquez?
Marc Márquez you already know diplopia in the first person. Therefore, He has undergone conservative and surgical treatments. The first option is always to wait for a spontaneous resolution before proceeding with an intervention.
It seems that I am experiencing déjà vu… During the trip back to Spain, I began to experience discomfort in my vision and we decided to visit Dr. Sánchez Dalmau who confirmed that I have a new episode of diplopia.
The Spanish motorcyclist knows it and has no other choice but to wait. Palsies of this type, due to head injuries, are only 25% of all fourth cranial nerve disorders. However, and fortunately, they are the ones that require the least surgery.
Marquez’s record shows that there are no immediate consequences for him not being able to get back into his vehicle. He will continue to compete. The risk of an accident is inherent in his professional career and he has known it since he was young.
