Hi There,
Thanks for getting back to me. I have had him for about 1 year now and this is the first issue he has had. So he is eating happily enough, is full of energy, eats live prey (fed every 2 days) and veges(only a few mouth fulls a day), has a new UV light (updated each 6 months), gets out in the sun on most days, but his eye is closed most of the time. It does open and there are no scars, irritations or swellings that I can see. I have added a picture of his setup.
We do not have many reptile vets in this country, and this has been going on for about a week. He has also just finished shedding.
