Conditions such as middle- and inner-ear infections are common causes of the disease. Your veterinarian may also prescribe certain types of medication depending on the diagnosis. Usually, the uncontrollable eye movement disappears within days. The vestibular apparatus is located in the inner ear and is responsible for maintaining our balance, and sense of orientation and direction. Vestibular disease is a condition in which a cat suddenly develops incoordination, falling or circling to one side, involuntary darting of the eyes back and forth (called nystagmus), a head tilt, and often nausea or vomiting. Idiopathic vestibular disease is a short-term, self-resolving condition. You may need to pick them up and carry him to the food bowl, to the water dish, or to the litter box. Nystagmus as a symptom of vestibular syndrome in cats is typically caused by mild trauma to or a disease of the vestibular apparatus, located inside the cat’s ear. Diagnosis may involve visualization through otoscopic exam or behind the soft palate, but usually needs radiographic evidence or more advanced imaging such as CT or MRI. Other common signs associated with nystagmus include head tilting and circling. Many affected cats are also deaf. There are two types of nystagmus: jerk nystagmus and pendular nystagmus. For benign tumors, complete surgical removal is curative. Nystagmus causes the involuntary and rhythmic oscillation of the eyeballs; meaning, the eyes unintentionally move or swing back and forth. Most cases are diagnosed based on clinical signs. The vast majority of cases are diagnosed as idiopathic, meaning the exact cause isn’t known. The technical term for unintentional eye movement in cats is called nystagmus. A cat’s eyes are pretty amazing.They allow a cat to see in near-darkness and provide her with a great ability to detect motion in order to hunt prey. Jerk nystagmus is characterized by slow eye movements in one direction with a rapid correction phase in the opposite direction, while pendular nystagmus is characterized by small oscillations of the eyes with no movement being distinctively slower or faster than the other.

Total ear canal ablation and bulla osteotomy (TECA-BO) is the most common surgical option. Your veterinarian will determine which tests are appropriate for your cat based on medical history, clinical signs, and physical examination findings. Nystagmus is often diagnosed via an analysis of cerebrospinal fluid, which can also reveal inflammation associated with the disorder. Ann. Vestibular disease is a disease that can affect cats of all ages. One such behavior: fluffing up his tail, arching his back and jumping sideways. This will depend on the severity of the condition. Post-treatment care is dependent on the cause diagnosed as well. Ear canal tumors can be benign or malignant. Learn more. They can cause stertor, nasal discharge, otitis, otic discharge and head tilt. While recovering, you may need to help the cat eat, drink, or go to the litter box. Having kept one cat alive for too long because I couldn’t let go, I now follow the rule that I’d rather let a cat go a week or two early than a day too late. Nystagmus-causing central vestibular disorders include tumors, thiamine deficiency, viral infections (such as feline infectious peritonitis), and consequent inflammation, heart attacks, hemorrhages in the heart, and exposure to toxins (such as lead). Treatment of ataxia will be influenced by the root cause. Siamese and Burmese breeds have been associated with an inherited or congenital form of the disease. My thoughts are with you at this difficult time. Spend enough time with your cat and you'll start to notice some rather odd behaviors and movements that don't seem to have an explanation. Exposure to certain toxins or drugs can also cause symptoms that mimic feline vestibular disease. A cat who won’t eat often means serious trouble. Nystagmus causes the involuntary and rhythmic oscillation of the eyeballs; meaning, the eyes unintentionally move or swing back and forth. Nystagmus can occur in both dogs and cats and is a characteristic sign of a problem in the animal's nervous system. Radiation therapy or chemotherapy may be pursued. Many cats will require assistance eating and drinking during the initial stages of the condition when their balance is most affected. There are several different forms of ataxia, depending upon where in the nervous system the abnormality occurs. I adopted Happy 11 years ago when she … Contributors: Ernest Ward, DVM; Updated by Malcolm Weir, DVM, MSc, MPH. Pain management, supportive care, and creating a safe environment (e.g., preventing access to stairs) are cornerstones of ataxia treatment. However, most veterinarians recommend a neurologic exam approximately two weeks after initial treatment to monitor for improvement or progression of the disease. These clinical signs usually appear suddenly, many times in less than an hour. It's a disease of the inner ear and it will cause staggering, falling over, one sided paralysis and the cat might hold his head at an odd angle.
