Blindness causes
I am confused and would appreciate insight here in NY.
My 12.4 lb, 15 year old female spayed domestic short haired tabby cat has gone blind. I thought I noticed slight pupil changes in one eye earlier this year but my partner told me it’s probably just how the light was hitting her eye. The pupil looked slightly crooked but she otherwise seemed normal. This weekend, I noticed she wasn’t tracking me while I walked around like she normally did and suspected she went blind despite navigating around the house perfectly fine and acting normal.
Took her to the vet for a full workup: kidneys were good, thyroid was ok, sugar was spiked but determined to be stress hyperglycemia, eye pressure was fine, no eye ulcers or scratches, nothing wrong looking with the eye but confirmed to be blind. Her blood pressure was 200 with a grade 4 heart murmur and positive NT-proBNP and appearance of slight enlargement on xray. Echocardiogram came back perfectly normal, so they determined the heart murmur and positive BNP was due to stress and anxiety. Which she is a very anxious cat when around anyone other than me and my partner or removed from her environment (she’s strictly indoors) Now she’s on 2.5mg once a day of amlodipine, but I’m worried if she actually needs it or only had high BP at the vet. I’m still giving it to her as usual and have a tech visit to recheck her BP while on the meds. But if she’s very anxious outside of our home, how can I be sure the BP tests are actually accurate? What if her blindness is not BP related but instead, something else?
What else can cause blindness? I am just worried something is being overlooked or misdiagnosed. I love my cat and hope she will be ok.
