A tooth or jaw abscess? Is a huuuge difference from getting a cut on the top of her head that abscessed.
A rabbit with chronic teeth issues that are abscessing is different from a one off injury.

Seriously? We are not recommending just leaving an injured rabbit to sort itself out when nobody even knows what body part is injured.
If you do not actually know what is injured doing anything like what some of these members are recommending can result in making the injury worse.

Best to just get him into a vet. You cant really check for scratches or ulcers at home.
You can flush the eyes with saline initially but if that doesn't work its time to stop messing with them and see a vet. Its too easy to cause vision loss with the wrong treatment.

While yes it appears they have mites or a fungal infection. Iy dowent typically kill that quick when it isnt that severe.
A more likely cause would be some type of toxin they have eaten. Myxo as Apollo said. A form of RHD. or...
You need to take him to a Rabbit Savvy vet if flushing the eye has not worked. Eye problems can be anything from a foreign body, infection, or tooth problem. Eyes should not be screwes with at home as it doesnt take much to cause vision loss. Please take him to a vet.
Yes please do not put anything on your rabbit yet!
Photos of the "wounds" first.

Yes theyre safe as long as your rabbit doesnt eat them. Like anything else.
Be cautious of the height.
I had one gal who LOVED her cylinder one that came from the walmart pet section. It was a carpeted cylinder with 2 holes and then the top she could jump on.
