So I took Pio out today to do some 'splorin, and his left eye looked a little funky to me. I don't know if this is something I'm just now noticing (doubt it) or something that has just recently occurred...but he looks like he may either have some sort of eye infection or the membranous tissue of eye turned inside out and is pushing up through the eye? I haven't touched it yet, just looking for opinions of what it might be?
I was going to try to clean it with a saline solution to dislodge any debris in his eye, then treat it with terramycin, or use a moistened q-tip to see if it's actually attached. Any help would be appreciated, thanks!

The eye that concerns me (left eye)

The right eye...everything looks good here
