I wish to ask you for advice regarding a matter.
This happened to my nephew recently.
He's 7. He and his brother accidentally headbumped each other when trying to pick something up the same time.
The hit was on the top of his forehead (which is AFAIK like to strongest part of the skull).
The collision did not hurt him at all, not the place of contact, no headache whatsoever. There was no bump on his scalp afterwards.
No loss of conciousness, no dizzyness, no difficulties in execution etc etc so basically no symptoms -
except that for like a second his vision darkened (and immediately returned to normal), in the same fashion when you suddenly stand up. (He knows about that symptom as he had it once).
Why do you think this happened? Do you think there was some injury to the brain afterall? Or was it just the impact shaking his eyes?
Thank you for the answer.

Hello and welcome,

I appreciate your concern,

If the pupils of both his eyes appear normal,he is not complaining of blurred or double vision out of one or both eyes then he most probably is fine.

If there was any brain damage,he would have shown symptoms of it by now.

The sudden darkening and then immediate return to normal vision could be due to loss of balance or the loss of blood supply for a quick second,which also happens when we stand up too quickly and brain is not fully perfused at the moment.

In my opinion it was just the bump causing him lose balance and not some brain damage.

I hope this is helpful,

Wishing you the best of health.
