The down side to the injections is that it may not work and the glaucoma and pain will remain. One injection may also not be enough for long term control. The up side would be the fact that it is less invasive and less painful. Eye removal is a more common procedure. It eliminates the glaucoma problem once and for all. The down side is that general anesthesia is needed, the procedure takes some time and thee will be some degree of post op pain. The eye is already painful so, there may not be any noticeable changes in degree of pain. Most dogs do very well after surgery and heal quickly. The other plus is that once the eye heals, eye meds are no longer needed.
This is helpful. But I was told that the pain would go away with the injection. So you're saying that my dog may still be in pain even after the injection and that the glaucoma could get worse?
