If you're the owner of a pet rabbit and you're concerned that your rabbit is developing cataracts, rest assured that this is a fairly common problem, which can potentially be corrected with early detection.
A cataract in a rabbit's eye is a noticeable clouding over of the lens inside the eye. Cataracts are not preventable, and usually caused by a bacterial infection.
Cataracts can cause gradual vision loss in rabbits if not properly detected. If left untreated, cataracts can cause glaucoma.
Laser surgery can remove cataracts that are detected early. Medication is often recommended after surgery to deal with the bacterial infection.
If the cataract is not removed, it is possible that your rabbit will become blind in the affected eye. Your rabbit can continue to live a normal life, however, as long as you adjust his environment accordingly.
PetMD states that many times, cataracts are present at birth, but can also occur spontaneously throughout the lifespan of your rabbit.
