Thanks for the replies guys! Hannah, I think your deduction sounds very possible too. It probably is a discharge related to either his eye or something else near his eye.
His snout unfortunately has always looked like that, not necessarily swollen. When I received him straight out of the shipment box last October as a baby, I had noticed the two "bulges" on the side of his head were kind of sunken and distorted, and that his snout was a different shape. The breeder sent me a bad hatchling, I guess. He also has some neurological/equilibrium problems, similar to a spider. But I didn't bother messaging him about it at the time, just to be nice. :s I kind of regret not doing that now. Hope he doesn't have a variety of issues in the future and die early or something.
Now I'm looking for a herp vet around my area (Los Angeles/Orange County). Does anyone know of a good one local to here? Or... I remember someone telling me a website a long time back where you can search up your local herp vets that are a member of that "herp vet association" website, with a name something like that... I don't remember what it was.
Albert, what is the ocular scale? Do you mean the discoloration on his eyeball? He has also had the weird coloration (light orange/blue eye) on both eyes, ever since I received him as a hatchling.
I am really regretting not messaging the breeder about getting his bad hatchling. I just didn't want to be a bother at the time, and thought Yukon would be fine when he's older. :| Bad decision. Too late to message now, I assume? LOL
