Hi there First I would say you need to get a different vet if that is the advice you were given. I hate to tell you this, but it looks like your chameleon has a virus I believe they call it Pox. I don't know the long technical name for it, that is the name in short. There is a girl named Ginger Scott who runs House of Chameleons Rescue. She has a veild that has got this and the eye growths looks exactly like that with those little spikes shooting out. The chameleon is also coverned in massive growths from the virus that just keep multiplying. Seeing that it is a virus, and not an infection, I do not know what type of meds can work for it. I do know it just keeps spreading and she has had many surgeries to try and remove the growths on this Veild. He is 100 times worse than yours. If you go on FB you can search her page. I would message her or write on your timeline. Post some pics of him on her page. I am pretty sure you are dealing with the same thing and in the early stages. She is also a member on here, but I never see her on here anymore so your best bet would be to contact her. I could be wrong, but I have never seen spiky growths like that, just on that Veild and that is what he has. Good luck with him! I am editing this as I think it is called the Papilloma virus that causes hornlike like growths. Still I would contact Ginger.
