|You can see in this photo the difference in the healthy eye and the Glaucoma eye|
There is basically 2 type of Glaucoma in rabbits the first is the type that has an underling cause like cataracts that develop when a bunny gets old like in Speedy's old pal Weasley,this can be treated with drops to control some of the symptoms caused by the Glaucoma.
The second is genetic found to be more prone in white breeds of rabbit with the albino strain, the bunny develop the symptoms from the age between 3 months and 6 months old as in Speedy's case we had him from 4 months old and he already had the symptoms,we just didn't realise it at the time what it was.His pupil in his left eye was enlarged and not reactive to light and fixed at a twisted angle facing forward and the whole eye was a bit bigger than the right eye but he seem to be able to see out of it so we let it go and just kept an eye on it.
Then in the summer after coming back from vacation we noticed that eye had developed a hazy appearance too,so we decided to take him to the vets after doing some research we suspected Glaucoma and that he was probably born with it.After taking Speedy to the vets it was confirmed it was Glaucoma and it was genetic.But the problem with this type drops do not work very well so we was advised to leave it alone as it was not causing Speedy any pain or problems.
The vet told us that the eye is full of fluid that is constantly draining away and replenishing to keep it healthy and when Glaucoma develops that doesn't happen properly so the eye becomes enlarged and becomes hazy after at time when the pressure builds up,In rabbits because their eyes are very stretchy they can take the pressure with out to much problem and cats eyes are the same but dogs eyes aren't as they are fibrous can can be quite painful which is why the eye is often removed in dogs.
So the prognosis is as long as Speedy does develop any infection or other problem they eye won't need to be removed,Speedy has already lost the vision in that eye but he isn't bothered by it and in my book that makes him a Super Hero!
