I might think that poor temperatures may be at the route of these problems. How are you heating the enclosure and what are the temp's on the cool and hot sides?

For hydration and proper shedding, a humid-hide is quite helpfull. It is as simple as a small plastic container with a hole cut into the side. Fill it with spaghnum moss and spray it down well. The humidity will be near 100% inside.

If you peeled off the scale covering the eye, it is now exposed. It can heal but is dreadfully susceptable to drying out and/or getting infected. I herp experienced vet will have to be seen. There isn't much they can do over the phone.

See www.arav.com for a starting point in finding a herp vet. Also contact your local herp society if you have one.

Good luck!
