When I am nervous or when the room is very lit and I look at the light, I have a white spot in front of my eyes and nothing is visible, then I have a headache and nausea 🤢?

You probably have no pathology, (it won't hurt to check) - this is good news, but everything is so complicated there (in the brain) that it is unlikely to be cured, and even, it is hardly possible to find a real reason (most likely, even with council of professors) - this is not very good news. The fact is that your eyes are all right, in general. The reason is somewhere at the junction of vision and the brain, on what connects them. Earlier (for a long time) Professor Sidorov worked in Moscow (at the Fedorov Institute), he treated eyesight in patients with diabetes, and knew a lot about these complex processes. In any case, to my question whether there are diagnostic methods that allow you to look deeper than the organ of vision and identify the factors affecting vision, he answered - yes. So you can ask people who treat eyes in complex connection with other diseases. Most eye specialists will not help you at all, because the problem is not there.

First of all, be sure to consult a neurologist and more likely to need an MRI of the brain.

This symptomatology can be the cause of associated migraine and your symptoms will then be included in the concept of an aura.

These are specific sensations / symptoms that patients experience before the onset of the main symptomatology.

MRI of the brain will first of all exclude the presence of organic pathologies of the structure of the brain, it is advisable to do this after consulting a doctor (perhaps he will recommend doing something else- then).
