I've never heard of those treatments before. Putting things like in a frog's eye could really do harm if you aren't 100% sure the source that is telling you to do it is a good one. Personally, I wouldn't risk it.
Right now, you may want to put him in a hospital tank (moist paper towels for bedding, change them every day) and keep his temp and humidity right. Correct husbandry conditions may boost his immune system enough to beat this. It's about the best info I can give you other than trying to take him to a regular vet and get antibiotics from there.

I have heard of people using baytril to treat things like this, but I have no idea on the dosage or delivery methods. Hopefully someone who has experience with that will see this.
