Hello all,
We noticed that our adult male cat (Max) had something unusual going on with his left eye this morning. It's as if half of his left eye is stuck dilated (open) as you'll see in the picture. It is creating an almost triangular shape. The normal half of his eye is dilating normally based on light, but the other half isn't. I looked up some things and everything about uneven pupil dilation points to anisocoria, but that's when one pupil dilates differently from the other. I can't find anything about a single eye dilating unevenly. I only noticed it this morning, and he's the kind of guy that always likes to be up in your face, so I would think I'd have noticed it sooner. I haven't heard any noises that would make me think he suffered some kind of trauma, neither of his eyes are red or have any kind of discharge. It doesn't seem sensitive as he kept head butting me (even on the left side) wanting attention. He's moving around just fine and was even playing a bit earlier. So he seems fine other than the way it looks, but I'm not sure what this is. Any thoughts?
