Anterior uveitis is inflammation inside of the eye; affecting the anterior uvea (iris and ciliary body). This disease causes redness, cloudiness, and typically squinting and a decrease in functional vision depending on the severity. Sometimes, especially in severe or untreated cases, it can cause glaucoma (increased pressure within the eye) by limiting the fluid that exits from the eye.
Corneal sequestrations, also known as corneal mummification, corneal necrosis, and corneal nigrum have been reported in the United States and Europe and are a unique disease process affecting the cornea of the domestic cat. The lesions usually develop slowly, are light brown to brown to black in color, and are usually located in the center of one or both corneas.
Entropion is a condition in which the eyelids roll in and result in eyelashes and facial hair rubbing against the cornea, which can lead to corneal ulcerations, corneal scarring, discomfort, and impaired vision.
Equine Recurrent Uveitis (ERU) is an immune-mediated inflammatory condition of the eye and is the most common cause of blindness in horses. It may affect one or both eyes. You may have heard other names for this disease, such as Moon Blindness, Iridocyclitis, and Periodic Ophthalmia.
Exposure Keratopathy Syndrome is a corneal disease that results in brown pigmentation that “grows” across the cornea. This is often concomitant with scar tissue formation and blood vessel infiltration.
Feline Herpesvirus type 1 (FHV-1) is believed to be the most common cause of ocular disease in cats. Multiple cat households, catteries, kittens and cats from pet stores, and feral kittens and cats are most prone to develop active FHV-1 as the disease process usually manifests itself in poorly conditioned felines as well as those that are experiencing stressful living conditions.
Hypertensive Retinopathy is a condition wherein high systemic blood pressure (hypertension) causes secondary retinal detachments and/or retinal hemorrhages and results in sudden complete or partial blindness. The problem tends to occur most frequently in elderly cats and those with kidney disease.
Immune-Mediated Eosinophilic Keratoconjunctivitis (IMEKC) is a unique syndrome found in cats. A particular type of white blood cell, the eosinophil, normally responds when the body is affected by allergies or parasites.
The iris is the colored part of the eye. In cats, an abnormally pigmented area of the iris may represent either a benign or a malignant lesion. There are two similar-sounding diagnoses that describe iris pigmentation in cats: iris melanosis and iris melanoma.
The naso-lacrimal duct (tear duct) is a passageway connecting the eye to the nose and mouth. Tears produced in the eye normally drain through this duct. There are two openings (puncta) to the duct on each eye; one is located on the upper lid, and the other is on the lower lid.
Prolapsed Gland of the Nictitating Membrane (PGNM) or Cherry Eye is most commonly seen in English Bulldogs, Cocker Spaniels, and Beagles and occasionally in certain feline breeds such as Burmese, Himalayan, and Persians.
Proptosis is a forward displacement of the eyeball such that the animal can no longer blink over the eye. The condition occurs most frequently in breeds with prominent eyes such as Pug, Lhasa Apso, and Pekingese, although it can occur in other species such as cats, horses, and exotics.
SCC is a form of skin cancer that affects the outer layer of skin cells. Ophthalmologically, it can develop in the eyelid margins, the third eyelid (nictitating membrane), or the cornea. It is the most common type of malignant eyelid tumor found in horses, cattle and cats.
