But we must consider that abandoned animals or those born in the streets are vulnerable to various diseases that can put their well-being at risk. That is why it is so important to provide adequate preventive medicine from the first weeks of life.
The uveitis in cats is an ophthalmological disorder that can affect the uvea of cats of all ages, being more common in stray cats. Among its most frequent causes are certain systemic pathologies, traumas, contusions and penetrating injuries due to fights or accidents. To learn more about feline uveitis, its causes and treatment join us to continue reading this new article.
What is the Uvea and What are its functions?
The uveal tract (or uvea) is a kind of vascular veil that represents the main protective barrier of the eye. Among its functions, the participation in the production of aqueous humor is responsible for lubricating the eyeball, stands out. Its structure includes a posterior portion, formed by the choroids and an anterior portion that includes the ciliary bodies and the iris. In this way, it forms an immunological barrier to protect the main internal components of the eye causing the cat eye infection.
Thanks to its delicate vascular structure, the uvea becomes very vulnerable to internal and external pathological agents to the body. When the uveal tract is affected, it usually involves dysfunctions in the immunity of the eye, which can cause partial or complete loss in the visual faculty.
Uveitis in Cats: Definition and Types
The term “uveitis” is applied by Veterinary Medicine to designate different inflammatory processes that support the uvea of felines and canines. Depending on the affected eye region, we have the following types of uveitis:
- Anterior uveitis: Affects primarily the iris and / or the ciliary bodies.
- Intermediate uveitis: Predominantly compromises the posterior portion of the ciliary bodies.
- Posterior uveitis: Develops mainly in the choroids.
As the boundaries between the components of the uveal tract are diffuse, it is common for inflammation to expand and jointly affect different uveal structures. In more advanced cases, uveitis in cats can reach the retina and lead the animal to blindness.
Causes Associated with Feline Uveitis
As mentioned previously, uveitis in cats is associated with endogenous and exogenous factors. Next we highlight the main causes of this pathology in domestic felines:
About 70% of cases of uveitis in cats are caused by severe systemic diseases such as:
- FeLV ( feline leukemia virus )
- FIV ( Feline Immunodeficiency Virus or “Feline AIDS”)
- PIF ( Virus of the Infectious Feline Peritonitis )
- Systemic mycoses
- Systemic toxoplasmosis
Many diagnoses of uveitis were made in cats with intraocular tumors, mainly in cases of iris melanoma. High blood pressure also appears as a risk factor for the development of uveitis, thrombosis and intraocular hemorrhages.
The exogenous causes of feline uveitis are almost always associated with street fights, accidents or traumas. The wounds, perforations, cuts and contusions derived from these phenomena can favor the appearance of uveitis.
Symptoms of Uveitis in Cats
The first symptoms of feline uveitis are considered homogeneous and silent. Therefore they are usually difficult to recognize early, since they are visual difficulties or disorders of the ophthalmological tract. A cat suffering from uveitis usually presents:
- Ocular hypotension
- Miosis (constriction of the pupils)
- Retraction of the eyeball
- Excessive tearing
- Hypersensitivity in the eye area
In addition, it can develop secondary diseases such as cataracts, glaucoma and retinal detachment.
A very characteristic aspect of the eyes affected by uveitis is the phenomenon known as Tyndall. The pathology causes the accumulation of erythrocytes, leukocytes and proteins in the aqueous humor, generating turbidity in the anterior portion of the eyeball. When subjected to the impact of light, these particles reflect continuously and can show spots on the eyeball.
Treatment of Feline Uveitis
The specific treatment of feline uveitis will depend on the recognition of the cause of the pathology in each animal. The veterinarian will proceed properly to reach a differential diagnosis and then may prescribe appropriate drugs to eliminate or control the progress of pathogenic agents.
Normally eye drops are used with corticosteroid and non-corticoid anti-inflammatories to control and prevent the progression of uveitis. In some cases injections of methyl prednisolone that are applied under connective tissue are also recommended. If the animal feels moderate pain, analgesics may be recommended to improve their well-being. If the cat suffered traumas and has perforations, surgical intervention accompanied by controlled administration of antibiotics will probably be necessary.
