My cat died (inside cat) of an infection to the brain caused by an eye injury. She lost both her eyes too because of the infection, the vet could do nothing.
If you want to save his eyesight and life, arrange for a vet as soon as it is possible.

I forgot the part that it was done by a stray cat she tried to chase away.
They are fucking nasty.

Likely to be a cat scratch/bite injury- cat's mouthes and claws are absolutely ridden with bacteria.

You need to get him to a vet, ignore >>2367725
here. As the swelling is behind his eyes I'd strongly advise you go sooner rather than later.

Cat needs antibiotics. Vet.
