Typically eye issues, in my experience, is from a lack of something in the diet and/or hydration issues. I have also had a vet look at a chams eye and was told it was not a problem and would clear up on its own only to see the problem resurface over and over. If it were me, I would make sure he is very well hydrated by means of injecting his feeders with water and feeding some hornworms until you are certain his urate is white with no signs of dehydration. Properly gutloading your feeders and keeping a good supplement schedule will hopefully get any imbalance corrected. Ontop of all that, I would get a small tube of terramycin and try putting a small dab with a qtip on the affected eye every other day for a week or so and see if that helps clear it up. If all else fails and the vet has no good treatment options, I have treated with vitamin A capsules and got past eye issues before. Jim Flaherty from the chameleon company has a thread on here that describes in good detail when the vitamin A dosing is warranted and how to adminster that treatment. You might want to look up that thread and see if that fits your current issue but that is a last resort after following good husbandry practices first to see if it corrects itself. JMO
