Opthalmology Cases

So lets start…

We got a mixture of responses here, all were good

Now we are set, what common problems do we see?

So common eye problems are:- conjunctivitis, corneal ulceration & eyelid disease
Less common problems are:- uveitis, glaucoma & retinal disease

Important to do a good examination, as Sarah shows here

So with a negative fluorescein we decided conjunctivitis is the likely diagnosis, what are the causes of this in cats?

Always important to remember the side effects of the drugs we are giving…

And we weren’t quite there with the diagnosis of FHV, PCR rather than virus isolation

Next case

We decided KCS (dry eye) was the most likely ddx, diagnostic with a STT <10mm/min. So why is there discharge on the eye?

We couldn’t get this one, but turns out the decreased production of the aqueous part of the tear film causes the mucous to appear- so we don’t need AB’s for this case!

How do we treat?

Remember to advise the owners these are lifelong treatments, and not a cure- need to be committed to putting those drops in for life!

Some great answers here, so remember if there is retinal haemmrhage-high b.p is likely. So what are the causes of high blood pressure in cats?

Emphasising the importance of eyes…they can represent systemic disease as well!
Our last case of the evening

So as its a terrier, always think of lens luxation!

So we need to measure the pressure in an eye with lens luxation, as it can lead to 2ndary glaucoma.

Now you’ve diagnosed the lens luxation what do you advise!

For those that are interested, its the ADAMTS17 gene test (lets hope that doesn’t come up in the finals exam!)

All the cases done, Rob opened the floor for any Q’s

Thanks very much to Rob for this evenings cases, hopefully some useful revision for all of us.
