For the last 4 months or so, by butterfly telescope has had a white spot inside of his pupil. At first I thought it may just be irritation from rubbing his eyes against the glass, but now that is clearly not the case. Recently, I noticed that it is actually 3D. I have included a video so you can see what it looks like. It is inside the eye, not on the lens. I think it might be a cyst? He is acting totally fine and is eating like a champ. I have no idea if he can see out of it (this has been unexpectedly hard to test), but he gets around just fine. I asked the guys at my LFS and they had no idea. Frankly, I'm stumped too. Any help is appreciated. Pan is a big goofy boy and I want to make sure he stays healthy for years to come.
