Sorry, I can’t see your picture as I’m on my phone so what I will say is based purely on experience;
A few weeks ago I posted about my buns eye changing colour and one of the replies suggested it could be related to the Vienna gene.
On Thursday morning we raced down to the vet in a panic because a tiny white spot had developed in the eye. They looked at it and were a little stumped, it’s not a cataract and it’s not a scratch. The two things they think it could be are;
-fatty deposits in the eye which is just one of those things, happens with no clear cause. This wouldn’t cause any issues except in later life if it became substantially bigger in Whig case there is a risk of ulcers
-the other possibility was; apparently does can sometimes get a surge of hormones that can cause such a flair up? I think this is more likely for Patsy based on her recent stompy, nippy behaviour (spay time this week, eek!)
Is your bun spayed? Domestic buns can still get that hormonal instinct as we come in to spring.
Patsy’s case has been referred to a specialist, so if it is the first possibility they will advise me on how to manage it and possible future ulcers.
As always, if you’re worried a vet trip is best, but (without seeing your pic) it sounds pretty similar and I’ll keep you posted on what the specialist says!
