Question from David Keown
My 9 year old GSD has a black disk like cataract in one eye. Can it be removed safely and what’s the prognosis for a good recovery. Would this be expensive to remove? Is this usually done by my vet or a specialist eye vet? Thanks.
Answer from Shanika Williams MRCVS online vet
Hi David, thank you for your question about the black disc in your GSD’s eye (German shepherd dog).
Firstly I will describe what a cataract is; I do not think that your dog has a cataract but an iris cyst.
A cataract is an area of discolouration in the lens of the eye, the lens sits in the middle of the eye and is usually colourless and clear, it sits just behind the iris (coloured part of the eye). Usually a cataract can only be seen without the use of specialist equipment if it is very large or the lens has dropped out of its correct position and has fallen into the front chamber of the eye.
So what is the black disc?
The black disc that you are describing in your GSD’s eye is most likely to be an iris cyst. Iris cysts are fluid filled black discs of varying size that bud off from another part of the eye. They vary in size (usually few millimetres in diameter) and can move around or are fixed in position; they are usually found at the front bottom half of the eye. I have personal experience of this condition as our family GSD had several mobile iris cysts.
Does my pet need any treatment?
