Sorry for the length but I'm trying to be as detailed as I can.
A little background: Libby is 11. Spayed, and no health issues at all in her history until a few months ago. She split a nail, had to be removed. Got infected and into the bone of the toe resulting in a toe amputation about a month ago. She was on antibiotics waiting about a month for the surgery but came through everything seemingly fine. She also had a bout of Horner's Syndrome, from a hard hit from our Chessie pup who hasn't figured out how big he is. That went away after about a week.
Friday evening she was panting but not enough to really be concerned and was showing no other signs of distress. She woke us up Sat morning having a seizure that lasted almost 5 minutes(no history of seizures). Completely unresponsive, tongue out, drool, feet kicking, released her bowels...I thought I was watching her die. A few minutes later she stood up like nothing had happened. The next hour or so though she was blind as a bat. Pacing up and down our hallway running into the wall/door/dresser every time she turned left to turn around. Through the day her vision seemed to improve, she ate fine, went outside to urinate and defecate with no issues, ears perked up and tail wagging when you talked to her. Since then she has had episodes with trembling, panting, and general uneasiness(pacing) followed by times of nothing at all but hard heavy sleeping.
Vet visit today: Blind in Left eye/"luxated lens"??? Right eye has some vision loss. No pain response with palpating. Normal Temperature. Blood work normal except for ALP but it is down from a month ago prior to the surgery. (Copy of blood work below). He gave her Deramaxx and Opthalmic neo/baci/dex drops.
So, could the lens be causing enough pain to make her tremble and pant like that? Any other thoughts?
