I am sorry to hear about Cleo's issues. This kind of thing always happens after hours and on weekends...always. Those pressure measurements bother me a lot, as done the speed with which this condition came up. It could be something as simple as a corneal scrape/ulcer or it could be something as serious as lens luxation or glaucoma.
This is what I tell my clients. No one knows eyes better than an ophthalmologist. If you want the best chance of restoring Cleo's vision, then a consult with the ye doctor is the way to go. If we can get those pressures down, then there is a chance that Cleo can see again. I would also want to make certain that there was no permanent damage to the retina or other part of the eye. The speed with which is came on really makes me concerned for acute glaucoma.
Decent vets, like ourselves, are general practitioners. We try our best to be great at everything but we use specialists as much as human doctors do...even though we hate to admit they know more than we do :)
I would consult with the eye doctor. see what is going on in that eye. 24 hours could make the difference between getting Cleo to see again or complete loss of vision. We could also get her out of any pain or discomfort that she might be in.
I hope that helps, please let me know if you have any other questions!
Well...honestly, glaucoma would be on the top of the list. Glaucoma is a build up of fluid in the eye which then leads to a build up of pressure and loss of vision. there are two ways that this can happen:
1. The eye starts to make too much fluid
2. Something blocks the fluid from leaving the eye: This one is most likely and could be due to a lens luxation, problems with the angles of the eyes, something wrong with the back of the eye, etc. which is why it is so important to have a specialist take a look.
Other causes of loss of vision include inflammation of the nerve that enters the eye, trauma to the eye, lens luxation, retinal detachment, high blood pressure, etc.
All of these things can be quickly ruled in or out by a veterinary eye doctor which is why I am so glad you decided to go. You obviously care a great deal about Cleo and hopefully everything is treatable and she will be back to 100% in no time!
