Joy & Holly

Brought my 13yo CAG into my local vet yesterday for wings/beak/talon trim. When we came back into the room her eyes were deep orangy red and she was really out of it. I flipped out and asked why her eyes were bleeding. That shook up the vet (non-avian, small animal only) who said that's normal from stress and would return to normal color within 12 hours. (I've had birds for 20 years, and Holly since she was a wee bappy thirteen years ago, and I have seen her little white face turn pink with anger, but I have NEVER seen her irises turn bloody like that.) I hurried up and got Holly back home then called my avian vet and sent over pictures of Holly's eyes. The a.v. said that she's never seen the eyes hemorrhage like that. It seemed to us that she wasn't seeing very well all evening and was spacey. I kept a close eye on Holly all night, and now this morning she is behaving and looking more like her normal self. I'm relieved but livid. My dog vet should NOT be grooming birds if he doesn't know how to do it safely, and I'm mad at myself for trusting him to do it. The reasons I didn't bring her over to my avian vet for a grooming are twofold. First, Holly gets a little car sick on the hills between here and there (over a half hour ride), and also the a.v. requires an expensive full blood workup and exam each year or they won't trim her wings. Today I'm dedicating myself to learning WTH happened in that room to nearly kill my bird. So my question for you is, has anyone here ever seen such a thing happen to their bird's eyes??? I have pictures on my phone but don't know how to get them here. Thank you, Joy (and Holly)
