Whoa! It looks very problematic firstly bc it's the head and eye of the animal. Both of which are critical body parts. Treatments for mammals can be very different than the treatments for reptiles. Remember snakes have a spectacle outer covering that protects the inner eye structures. This animal has a very large swelling of the eye and surrounding structures and scales. A trip to the exotic vet is my recommendation. The flaking over the whole body is a attempt to shed but bc the animal is sick or injured or both the shedding is poor.
