47. As such, blood urea nitrogen and serum creatinine concentration monitoring is recommended.37. A full ophthalmic examination is required to determine which portions of the uveal tract are involved. 42. Glaze MB, Gelatt KN. Dysfunction of the sympathetic nerves of the eyes and surrounding facial muscles causes Horner’s syndrome and may be due to an injury such as a bite wound or blunt trauma, a tumor, intervertebral disc disease, or middle or inner ear disease. Specific therapy is directed at the underlying ocular or systemic cause of uveitis. 23. Anatomically, uveitis is classified as anterior if the iris and ciliary body are inflamed (iridocyclitis). If only the ciliary body and the iris are inflamed, the condition is called anterior uveitis, while inflammation of only the choroid is called posterior uveitis. This DNA alpha-herpesvirus is widespread among the general cat population.30,31 The virus is shed in ocular, nasal, and oral secretions and transmitted mostly by direct contact, although indirect transmission can occur.30 After infection, about 80%31 of cats become latently infected carriers. Figure 9. 3rd ed. Dubey JP, Lappin MR. Toxoplasmosis and neosporosis. Gilor C, Graves TK, Barger AM, et al. Important historical information to obtain relates to the patient's environment (indoors vs. outdoors), use of flea preventives, travel history, history of trauma, duration of clinical signs, and the presence of any clinical signs often associated with systemic illness, such as inappetence and lethargy. Horner's syndrome is a common neurological disorder of the eye and facial muscles and can occur suddenly. Feline coronavirus infections. Feline systemic fungal infections. Buphthalmia is demonstrated in the left eye by the increased width of the palpebral fissure and increased corneal diameter compared with the right eye. 45. An anterior segment evaluation is best performed by using a hand-held slit lamp. There are many potential causes of uveitis. Vet Pathol 2005;42(3):321-330. In order to assess the initial response to treatment, your veterinarian will need to examine your cat frequently, sometimes daily. Once a specialist has diagnosed your cat… Polymerase chain reaction for the detection of Toxoplasma gondii within aqueous humor of experimentally-inoculated cats. Vasculitis is a hallmark of the disease and occurs secondary to the activation and circulation of monocytes.27 The clinical syndrome in cats occurs as either an effusive or noneffusive form; the noneffusive form is most commonly associated with ocular lesions.25 Such lesions may be present in either the anterior or posterior segment of the eye and may include iritis, keratic precipitates, fibrin within the anterior chamber, hyphema, chorioretinitis, and retinal perivascular cuffing.25, Diagnosing FIP is difficult since no reliable diagnostic testing methods are available at this time. Canine and feline uveitis. Diagnosis and treatment. 3rd ed. In: Greene CE, ed. © 2020 MJH Life Sciences and DVM 360. Comparison of the hypotensive and other ocular effects of prostaglandins E2 and F2 alpha on cat and rhesus monkey eyes. Lappin MR, Black JC. Care for cats with uveitis … 14. ), In patients with chronic uveitis and resulting miosis and iridal swelling, the pupil margin may adhere to the anterior lens capsule, resulting in posterior synechiae (Figure 4).3 In these cases, the pupil margin appears irregular and the pupil fails to respond appropriately to light and dilating agents.3 If the entire pupil margin is involved, anterior movement of the aqueous humor is inhibited, resulting in aqueous humor accumulation behind the iris. English RV, Davidson MG, Nasisse MP, et al. When properly treated, most cases of uveitis begin to improve within twenty-four hours. An iridal mass in a patient with lymphosarcoma resulting in dyscoria (altered pupil shape) in the left eye. Feline ophthalmology. If the uveitis is due to an infectious agent, specific anti-infective therapy will be prescribed. In: Martin CL, ed. In: Greene CE, ed. Sometimes there may be bleeding or pus in the front chamber of the eye. The most common neoplastic disease secondary to FeLV infection is lymphosarcoma,17 which is a significant cause of uveitis in cats.19 Clinically, lymphosarcoma manifests as iridal thickening with associated flesh-colored lesions (Figure 8).17 These lesions are most commonly nodular but may be diffuse, with diffuse lesions appearing similar to uveitis secondary to other causes.20 Other ocular findings may include pink vascular corneal masses, hyphema, orbital disease,17 retinal degeneration, and hemorrhage.17,18, Figure 8. Addie DD, Jarrett O. Blastomycosis. Some cats with uveitis have tested positive for infection from Bartonella, a bacteria that causes what is commonly called "cat-scratch fever" when transmitted to humans. In: Greene CE, ed. Special diagnostic procedures such as ultrasound may be used to examine the eye, and your veterinarian may recommend a referral to a veterinary ophthalmologist. Ames, Iowa: Blackwell Publishing, 2007;62-98. We’re committed to keeping clients and staff safe during COVID-19 with NEW admittance and check-out processes. The ciliary body produces a fluid called the aqueous humor that provides important nutrients to the eye and that maintains intraocular pressure (IOP). Lappin MR, Roberts SM, Davidson MG, et al. Ophthalmic anatomy. Ophthalmic disease in veterinary medicine. Nonspecific therapy of uveitis is needed to minimize ocular inflammation, reduce pain, and prevent complications (see sidebar titled "Nonspecific therapy for uveitis). Arrowheads denote the superior aspect of the luxated lens. 2. A cat with uveitis resulting from a systemic illness with FeLV, FIV, FIP may be contagious to other cats. Thus, this procedure is typically limited to patients that are blind or nearly blind.7 Procedures to acquire aqueous and vitreous humor can carry serious complications since structures within the eye may be inadvertently damaged. Department of Veterinary Clinical Sciences. 39. The uvea is a part of the feline eye and it is in charge with supplying blood to the retina. 3rd ed. 41. Aqueous humor dynamic in experimental iridocyclitis. Early diagnosis and treatment can help preserve a cat's vision. Sellon RK, Hartmann K. Feline immunodeficiency virus infection. Additional testing modalities are available on aqueous humor samples, including PCR tests for various infectious agents, cytologic examination, and bacterial culture and antimicrobial sensitivity testing. 3rd ed. Uveitis can lead to secondary glaucoma because aqueous humor flow through the pupil or out of the iridocorneal angle becomes impaired. ©Copyright VCA Hospitals all rights reserved. With acute uveitis, the pupil is usually constricted. A complete cataract secondary to chronic anterior uveitis. Philadelphia, Pa: Lippincott Williams & Wilkins, 2000;320-329. Treat secondary glaucoma with carbonic anhydrase inhibitors and beta-blockers to decrease aqueous humor production. The disease processes that can lead to uveitis, although discussed individually in this article, can occur concurrently in a patient. Vet Comp Ophthalmol 1995;5(1):34-41. Bartonella infection in domestic cats and wild felids. Samuelson DA. Diagnosis of Toxoplasmosis in Cats … J Feline Med Surg 2001;3(1):9-16. In this article, we review the pathophysiology, clinical presentation, causes, and treatment of uveitis in cats. Uveitis in cats results from many ocular disorders or systemic diseases. Samples are collected by aqueous humor paracentesis, which is performed under general anesthesia. In: Gelatt, KN, ed. 32. This lentivirus causes an acquired immunodeficiency syndrome in cats.17,21,22 Many modes of transmission are thought to be possible, including in utero and postpartum through milk22 ; however, bite wounds are thought to be the predominant cause of viral inoculation.23 In patients infected with FIV, there is a progressive depletion of the CD4+ helper T lymphocyte population with a coinciding decrease in CD8+ T cells late in the disease process.24 Feline acquired immunodeficiency syndrome can occur months to years after primary infection with FIV and is associated with severe secondary infections, neoplastic diseases, and neurologic disorders.17,21 Ocular lesions seen in patients infected with FIV may include pars planitis, glaucoma, and chronic conjunctivitis,17 but anterior uveitis is the most frequent clinical finding.22 Ocular inflammation is thought to occur either directly in response to a cytopathic effect of the virus or secondary to immune stimulation by viral antigens in ocular tissue.22 Uveitis may also occur secondary to immunodeficiency and associated opportunistic infections with organisms such as Toxoplasma gondii.17,22, Because FIV induces a persistent infection, a definitive diagnosis is most commonly achieved by detecting FIV-specific antibodies in blood through either an ELISA or rapid immunomigration-type assay.17,21 False positive results can be seen in cats that have received the FIV vaccine or in kittens < 12 weeks of age that have passively acquired anti-FIV antibodies from an infected or vaccinated mother.21 False negative results may also be observed in the acute phase of infection when the antibody response is undetectable.21 Treatment of ocular lesions should include nonspecific therapy of uveitis (see sidebar titled "Nonspecific therapy for uveitis"). It is one of the most common parasitic diseases and infects nearly all warm-blooded animals, including pets and humans. Sometimes there is blepharospasm and increased lacrimation but this is less frequently encountered than in dogs, mainly because uveitis in cats … ), In cats with chronic posterior uveitis, the posterior segment may exhibit changes in pigmentation, retinal vascular attenuation, and tapetal hyperreflectivity secondary to retinal degeneration and scarring after the resolution of chorioretinitis.2 The globe may become smaller secondary to impairment of aqueous humor production by a chronically inflamed ciliary body.2. Four viral diseases in cats have been associated with uveitis—feline leukemia virus (FeLV) infection, feline immunodeficiency virus (FIV) infection, feline infectious peritonitis (FIP), and feline herpesvirus-1 (FHV-1) infection. Beekhuis WH, McCarey BE. 12. In dogs, uveitis is a common complication of … Coccidioidomycosis in 48 cats: a retrospective study (1984-1993). Bartonella spp infection as a possible cause of uveitis in a cat. Treatment of feline herpesvirus-1 associated disease in cats with famciclovir and related drugs. Rubeosis iridis is also evident. Uveitis is an inflammation of one or more of the structures making up the uvea. In most cases, the visible parts of the eye will be intensely red, including the sclera (the white part of the eye) and the conjunctiva, and your cat may have difficulty seeing. It’s not over when it’s over. Mycopathologia 2007;163(2):59-66. Angell JA, Shively JN, Merideth RE, et al. A superficial corneal ulcer is also seen centrally. If all three structures are involved, the condition is called panuveitis or true uveitis. Cats … 4th ed. Traumatic anterior lens capsule disruption. Infectious diseases of the dog and cat. Fontenelle JP, Powell CC, Hill AE, et al. Prevalence of serum antibodies against Bartonella species in the serum of cats with or without uveitis. Uveitis in cats may occur spontaneously or secondary to systemic disease. Treatment is initially aimed at reducing inflammation and providing pain relief primarily with topical eye medications such as corticosteroids (prednisolone, dexamethasone) or non-steroidal anti-inflammatory drugs, such as flurbiprofen (brand name Ocufen®). J Am Vet Med Assoc 1992;201(7):1010-1016. This type of bacteria lives in the lining of the blood vessels and is often spread by contact with flea feces. Hoskins JD. In addition to nonspecific topical therapy for uveitis (see sidebar titled "Nonspecific therapy for uveitis"), azole antifungal therapy with or without adjunctive amphotericin B therapy has been effective.37,43,45 Fluconazole is the azole of choice in cats since it is associated with the fewest side effects7 and has good penetration into the eye. Toris CB, Pederson JE. Intraocular disease associated with feline immunodeficiency virus infection in cats. Clinical aspects of natural infection with Blastomyces dermatitidis in cats: 8 cases (1991-2005). Complications are more common after very severe or recurrent cases of uveitis. The ciliary body provides nourishment for and removes wastes from the cornea and lens via the production of aqueous humor. (Photo courtesy of Dr. Ellison Bentley. There is a myriad of potential causes, and prompt diagnosis and intervention are needed to save and preserve a patient’s vision. Infectious Diseases, Medical Conditions, Pet Services. 16. A cat with uveitis … Am J Vet Res 1989;50(1):158-160. ANATOMY AND PATHOPHYSIOLOGY. Table 1: Possible Ocular Signs and Complications in Cats with Uveitis, Clinical signs associated with uveitis in cats can vary widely and may not be as prominent as signs seen in other species (Table 1). Kipar A, May H, Menger S, et al. One of the goals of treatment is to prevent secondary complications from developing. ), Intraocular pressure is often decreased in patients with uveitis because of prostaglandin-mediated inflammation5 and edema of the ciliary body resulting in impaired aqueous humor formation or increased aqueous humor outflow through the uveoscleral route.6, Figure 3. Diffuse iridal melanoma was diagnosed on histologic examination. Vennema H, Poland A, Foley J, et al. Posterior lens luxation secondary to chronic anterior uveitis. Severe uveitis can result in irreversible blindness. Uveitis may only involve one eye, or it may occur in both eyes at the same time. Viral diseases such as feline leukemia ( FeLV ), feline infectious virus ( FIV ), feline infectious … Classifying uveitis can help you determine what diagnostic steps will be required when presented with a cat that has uveitis. Pain is often associated with acute uveitis and is observed clinically as blepharospasm, photophobia, enophthalmos, third eyelid elevation, or epiphora.2,3, Aqueous flare, which is diagnostic of anterior uveitis (Figure 1), occurs secondary to the breakdown of the blood-aqueous barrier and increase in aqueous humor protein concentration.2,3 Purulent material or blood may also accumulate in the anterior chamber, resulting in hypopyon or hyphema, respectively (Figure 2).2, Figure 1. While T. gondii seldomly causes significant symptoms in healthy adults either (see below for exception… St. Louis, Mo: Saunders, 2006;754-767. Uveitis may occur suddenly (acute uveitis) or may develop more slowly (chronic uveitis). Virology 1998;243(1):150-157. Of these, about 45% of cats can have virus reactivation, resulting in clinical disease or asymptomatic episodes of viral shedding spontaneously or after periods of stress.30,31. Wilcox BP, Peiffer RL Jr. The main difference between these two conditions is that with uveitis, intraocular pressure (IOP) is reduced (low) whereas with glaucoma it is elevated (high). Infectious diseases of the dog and cat. A complete and thorough physical examination of your cat must be performed since uveitis is a symptom of many generalized illnesses. These primary ocular tumors must be differentiated from metastatic tumors such as lymphosarcoma, hemangiosarcoma, and adenocarcinoma. In some cases, histologic evaluation has demonstrated uveal lymphocytic-plasmacytic cellular infiltrates. In addition to nonspecific therapy (see sidebar titled "Nonspecific therapy for uveitis"), topical antiviral medications, including trifluridine and idoxuridine solutions, are efficacious against FHV-1 conjunctivitis and keratitis when administered as one drop in the affected eye four to six times a day for two to three weeks.34,35 As most antiviral agents are virostatic, frequent application is needed. Enzyme-linked immunosorbent assays for the detection of Toxoplasma gondii-specific antibodies and antigens in the aqueous humor of cats. (Photo courtesy of Dr. Kirk Ryan. 38. A second positive test result is highly suggestive that the patient is persistently infected.17 Identifying neoplastic lymphocytes on histologic examination of mass lesions or cytologic examination of aqueous humor is diagnostic of ocular lymphosarcoma; however, such samples may be unrewarding, and detection of neoplasia in other body systems may be necessary.19, With regard to ocular lesions, a positive FeLV status should be evaluated with caution as not all cats infected with FeLV develop lymphosarcoma, and, as previously discussed, FeLV infection may result in uveitis secondary to other infectious diseases as a result of immunosuppression. Blondin N, Baumgardner DJ, Moore GE, et al. Acute ocular FHV-1 infection can typically be diagnosed with virus isolation from conjunctival cytology samples.31 Other diagnostic tests available include serology and serum neutralizing antibody titers, fluorescent antibody testing on corneal or conjunctival smears, and PCR tests.30,31,33 Serologic tests are of limited value since most cats have been exposed to or vaccinated against FHV-1.32. Antibodies against the organism have been documented in the serum of cats exhibiting uveitis15,16 and healthy cats.14 In one report, the seroprevalence of B. henselae was higher in both healthy cats and cats without ocular disease compared with cats with uveitis.14 Serology is thus unlikely to aid in diagnosis. © 2020 MJH Life Sciences™ and DVM 360. Nasisse MP, Guy JS, Davidson MG, et al. 24. Penetrating ocular trauma may result in lens capsule rupture.8 Release of lens proteins causes severe inflammation (phacoclastic uveitis) of delayed onset after the traumatic event.9 With tears in the lens capsule > 1.5 mm, loss of the eye will often occur without early lens extraction.10 Additionally, penetrating trauma may result in the introduction of bacterial or fungal contaminants. It is one of the most common eye … If an underlying cause can be identified, treatments will target that; however, many cases will spontaneously recover after some time. Effect of topical ophthalmic application of cidofovir on experimentally induced primary ocular feline herpesvirus-1 infection in cats. Many of the signs of uveitis are similar to glaucoma. A slit lamp photo of a patient with ­anterior uveitis and resultant aqueous flare (arrowheads). Any event affecting the cornea, such as perforation or ulceration, can result in uveitis through the stimulation of an axonal reflex that is mediated by trigeminal nerve endings. Histoplasmosis is caused by Histoplasma capsulatum, a dimorphic fungus most commonly found in bat and bird feces.37,41 Infection occurs primarily by inhaling aerosols containing infective spores.37,41 Most affected cats present with vague systemic signs, including anorexia, lethargy, weight loss, fever, and anemia.37 Infrequent findings include pulmonary involvement, skeletal infection, and cutaneous lesions.37 Ocular involvement is thought to be more common with disseminated histoplasmosis than with other feline systemic mycoses.37 Ocular lesions may include mucoid ocular discharge, blepharospasm, conjunctivitis, granulomatous blepharitis, endophthalmitis, chemosis, anterior uveitis, chorioretinitis, retinal detachment, and secondary glaucoma.37,41,42, Coccidioidomycosis. Basidiospores of Cryptococcus neoformans cause the disease; the mode of transmission is thought to be inhalation.37 Pigeon droppings serve as the principal reservoir for the yeast.37 Affected cats typically develop respiratory and cutaneous manifestations, but they may also exhibit neurologic signs secondary to direct extension of the organism through the cribriform plate.37 Ocular signs unrelated to neurologic disease are thought to occur secondary to hematogenous dissemination of the organism and include both anterior uveitis and chorioretinitis.37,38 Chorioretinal lesions vary in appearance from single to multifocal and pinpoint opacities to large circular lesions.37, Blastomycosis. View the eye perpendicular to the light source to evaluate the anterior chamber for flare, cellular accumulation, or changes of the iris face. Indirect ophthalmoscopy requires a focal light source (Finnoff transilluminator) and a hand-held lens. (Photo courtesy of the University of Wisconsin-Madison. J Am Anim Hosp Assoc 1991;27(4):410-414. Nasisse MP, van Ee RT, Wright B. Ocular changes in a cat with disseminated blastomycosis. Martin CL, Carmichael KP, Vigantas KR, et al. The uvea, or vascular tunic of the eye, is composed of the iris and ciliary body anteriorly and the choroid posteriorly. Learn more. Upon dilation, it is possible to detect inflammatory cells in the anterior vitreous, known as pars planitis. Cats with uveitis are normally presented because the owner has noticed a change in appearance of one or both eyes. Although cats are a necessary part of the life cycle of T. gondii, the parasite rarely causes clinical disease in them. 28. The most common clinical ocular manifestations of FHV-1 are conjunctivitis and keratitis, but anterior uveitis has also been a suggested manifestation of the disease.32 One study demonstrated FHV-1 DNA in the aqueous humor of 12 of 86 cats with clinical signs of anterior uveitis that had negative test results for other known causes of feline uveitis.32 This study proposed that FHV-1 gained entry into the eye through axonal transport of virus, but this hypothesis has not been investigated.32 As previously discussed, FHV-1 may reactivate in times of stress, so it remains unclear whether the intraocular FHV-1 infection is a cause or result of feline uveitis.31 Additionally, FHV-1 can replicate in conjunctival and corneal tissue and could serve as a contaminant during anterior chamber paracentesis. Trauma-associated sarcomas are primary ocular tumors that may present clinically with chronic uveitis, glaucoma, intraocular hemorrhage, or white to pink masses.11 These neoplasms are typically detected an average of five years after a traumatic ocular event and are highly malignant.11 An association with lens capsule rupture and the development of these tumors has been reported.12. The best course of treatment will address the clinical signs but also any primary condition that the uveitis is a result of. The retrovirus FeLV is transmitted both horizontally and vertically among cat populations.17,18 Two disease progressions are possible in cats infected with FeLV: 1) persistent viremia and progressive infection or 2) self-limiting, regressive infection.17 Numerous FeLV strains exist, some of which can lead to malignant transformation or cytopathic deletion of specific lymphocyte and hematopoietic cell populations.17, A low incidence (< 2%) of ocular disease has been reported among cats infected with FeLV.18 Ocular lesions in cats with FeLV infection are unlikely to be the direct result of FeLV infection but rather neoplasia induced by the virus or related to secondary invasion of infectious agents caused by immunosuppression. Multifocal dark-gray (hyporeflective) lesions are seen scattered throughout the tapetal fundus indicating an active inflammatory process. Flare … Vet Pathol 2003;40(4):355-362. The aforementioned mycotic diseases can be diagnosed based on clinical findings, the results of serologic testing, and demonstration of an organism by cytology or histology.37 In cats with ocular lesions, aqueous aspirates are rarely rewarding, but histologic examination of an enucleated eye37,39 or vitreous or subretinal aspirates37 is likely to demonstrate organisms. It is often confused with other inflammatory conditions of the cornea and/or … Am J Vet Res 2008;69(2):289-293. Vet Parasitol 1998;79(3):181-186.

Infectious diseases of the dog and cat. 25. Causes of feline uveitis. Infectious diseases of the dog and cat. A patient with lymphosarcoma presenting with hyphema, hypopyon, and dyscoria (an abnormally shaped pupil) in the left eye. Feline histoplasmosis with ocular involvement. For example lymphosarcoma in cats is often manifested as iritis, while uveitis associated with feline AIDS has been associated with pars planitis. ), Pupil dilation with tropicamide ophthalmic solution is required to evaluate the posterior segment. Uveitis often occurs secondary to an acquired ocular or systemic disorder; however, in many instances the underlying cause is not identified despite extensive diagnostic testing. Some of the other symptoms that may indicate anterior uveitis include: Eye redness Squinting Excessive blinking Avoidance of lights Watery, mucus, or pus discharge from the eye Unusual color … Pathogenesis of experimentally induced feline immunodeficiency virus infection in cats. Andrew SE. ), The most commonly used FeLV testing method is a peripheral blood ELISA that tests for the presence of the p27 antigen.17,18 As previously discussed, cats can develop a self-limiting regressive infection, so a positive ELISA result should be confirmed with an immunofluorescent antibody test or a second ELISA performed three to four months after the first test. Therefore, feline uveitis is an important disease to diagnose and treat correctly, to decrease the chances of the eye being blinded and possibly removed, or even of the cat dying from the disease that caused the uveitis. Invest Ophthalmol Vis Sci 1987;28(3):477-481. Vestibular Disease in Dogs and Cats. (Photo courtesy of Dr. Kirk Ryan. This is usually a colour change, cloudy or red being most common. St. Louis, Mo: Saunders, 2006;88-102. J Vet Intern Med 1995;9(2):86-91. Inflammation of the choroid is termed posterior uveitis or choroiditis. Place the direct ophthalmoscope close to the eye, and focus it on the cornea. Uveitis is a general term that does not denote any specific underlying etiology.3 The causes of uveitis are numerous and, in part, depend on the cat’s geographic location, travel history, … The iris and the ciliary body together form the anterior uveal tract. Several diagnostic methods are available, including serology, fecal examination, aqueous humor PCR testing,48 and aqueous humor antibody detection.47 But the only means to definitively diagnose the disease is to demonstrate the organism on ocular histologic examination. : preliminary studies in cats Wilkins, 2000 ; 320-329 is to prevent secondary complications from developing 1981!
