The vet did a stain on her eye, turned the lights off and used the hand-held light(not sure if it's special) to check her eye: Nothing, no sign of anything.
About 5 minutes later when we were about to leave the clinic, the vet saw the stain had taken hold and she could clearly see two ulcerations that did not show up when she looked with a strong light in the darkened room.
The vet was really shocked and said she'd just learned something new about pink eyed pigs: You can't see the stain results in the dark with the strong light because the light goes right thru the eyes. You can only see the stain results in normal lighting. If I hadn't been chatting with the vet and time had passed, the ulcerated eye would not have been caught
Although the patient was a skinny I suspect this would apply to all pink eyed pigs.

I have one more PEW here and if he ever gets an eye injury I'll be sure to take him in for a stain. Thanks for the heads up.
From what I understand, the stain gathers in areas of unevenness (such as an ulcer or scratch) so those areas look green under the Woods Lamp. The animal hosptial I work at sees dogs and cats only so I have no idea about the PEW thing. Very interesting though. I'll ask when I go in today.
Makes me wonder if any PEWs might have been sent home without eye meds after a stain that showed nothing under black light.
Hopefully other people will post results of their PEW eye stains and whether or not they flouresced under black light.
Her eyes were as pink as a PEW and as transparent.

So if Bliss had some pigment, then there's a chance that other pink-eyed pigs would have the same problem. I'd say maybe this warrants a mention on the eye page as a possible thing to watch out for?
Perhaps a suggestion to watch for flourescing under normal light if staining pink eyes, if nothing is seen initially under black light?
My hunch is that it's the light pink eyes that are of concern. The ones that you almost think you can see right thru them to the brain. I guess the thread name should be changed to Staining Pink Eyes - but that does seem more confusing than Staining PEW Eyes.
Lynx, I put this in Reference so it doesn't get lost(and it seemed referency).
