When working to understand eye issues, it's important to understand that the iris, ciliary body, and choroid make up the uvea, which is the middle layer of the eye. The uvea has a rich blood supply. Changes to the eye can be seen as a window that alerts us to diseases originating in other places in the body. Iridocyclitis, or anterior uveitis, affects specifically the iris and ciliary body only, and can be a very painful condition. Eye inflammation may occur as an idiopathic (of unknown cause) event but is often linked to many serious disease processes.

If you notice that your pet’s eyes look abnormal, a visit to the veterinarian is crucial. The underlying cause must be investigated without delay. This is important because further deterioration of the condition of the eye and the risk of permanent vision loss are scenarios to be avoided. Your dog is also most likely in pain. The following symptoms are indication of anterior uveitis:

Because eye inflammation is usually secondary to an underlying disease, there are many causes that can be attributed to the condition:

When you bring your dog to your veterinary caregiver, expect a very thorough examination and diagnostic procedure. Ocular issues can quickly develop into permanent damage such as loss of sight. As a pet owner, it is entirely possible that you will not be aware of the extent of your dog’s vision loss. Timely treatment and resolution are key to maintaining vision, and to the reduction of symptoms and pain.

The veterinarian will begin by investigating the complete medical history of your dog. A physical examination will follow, which will include a visual inspection of the internal and external portions of the eye. As well, a measurement of the intraocular pressure of the eye, a fairly simple procedure, will be done. A microscopic examination is possible, which involves drawing fluid from the eye for analysis.

The veterinarian will order tests to check for the presence of autoimmune disease, and the possibility of infectious organisms. A complete blood count and biochemical profile are to be expected as well.

As is always the case when a secondary disease process may be involved, the underlying issue must be resolved along with the treatment of the inflammation. The first issue that the doctor will work to address is the reduction of inflammation in the eye. Of equal importance is the elimination of pain.

The protocol for the care of eye inflammation will include drops or ointment, and medication (often corticosteroids), all of which will aid in the relief of pain and swelling. Regulating the dilation of the pupil is important in order to maximize the correction of vision.

If an infection is found, antibiotics will be prescribed. Further damage resulting from scarring, retinal detachment, dry eye or ulcers will be treated. The repair of tears or a remedy in the form of removal of a foreign object may be needed to rectify the eye inflammation. In some severe cases, surgical removal of the eye will be advised.

The prognosis for eye inflammation is often good. Many owners will see an improvement in the condition of their dog’s eyes within 24 hours of the first administration of eye drops.

If the veterinarian has prescribed eye drops or ointment to be given at home, your vigilance as a pet owner is key to a successful recovery. Not all dogs will cooperate fully when the eye drops are being dispensed; there is a natural reaction to close the eye or pull away when a foreign substance comes near. Patience on your part is very important. Before you leave the veterinary clinic, ask for a demonstration on how to apply the ointment or execute the eye drop procedure.

There may be a variation in the type of drops, depending on the use and expectations. Pay careful attention to the instructions. The concentration of the medication and how many times per day to give the drops are two important factors to be aware of. Consistency is paramount to a complete resolution of the inflammation. Never stop the eye drops or ointment abruptly; a gradual decrease is necessary.

The veterinarian will want to examine your dog periodically over the next few days or weeks to check on ocular pressure, drainage and vision correction. It should be noted, especially in cases where the owner has delayed, that severe cases of uveitis may result in a permanent visual deficit or the need for surgical removal of the eye.
