Anterior uveitis (iridocyclitis) is the most common, with the incidence of uveitis overall affecting approximately 1:4500, most commonly those between the ages of 20–60. Symptoms include eye pain, eye redness, floaters and blurred vision, and ophthalmic examination may show dilated ciliary blood vessels and the presence of cells in the ...
Anterior lens luxation in a dog Anterior lens luxation with cataract formation in a cat. Ectopia lentis is a displacement or malposition of the eye's lens from its normal location. A partial dislocation of a lens is termed lens subluxation or subluxated lens; a complete dislocation of a lens is termed lens luxation or luxated lens.
Anterior uveitis (inflammation of the iris and ciliary body) is most common in dogs. The disease is usually immune-mediated in dogs, but may also be caused by trauma, cataracts, infectious canine hepatitis , leptospirosis , ehrlichiosis , or systemic fungal infections.
[18] [19] This disease has been observed in dogs in Africa and the United States, and in foxes in Scandinavia. In cats, the main cause of Encephalitozoonosis is eye infections, specifically phacoclastic uveitis, focal clouding of the lens, and anterior uveitis, with the mouse strain (type II) being the most likely trigger.

Because uveitic glaucoma is a progressive stage of anterior non infectious uveitis, uveitic glaucoma involves signs and symptoms of both glaucoma and uveitis.. Patients with acute non infectious anterior uveitis may experience the following symptoms: pain, blurry vision, headache, photophobia (discomfort or pain due to light exposure), or the observance of haloes around lights.
Fuchs heterochromic iridocyclitis (FHI) is a chronic unilateral uveitis appearing with the triad of heterochromia, predisposition to cataract and glaucoma, and keratitic precipitates on the posterior corneal surface. Patients are often asymptomatic and the disease is often discovered through investigation of the cause of the heterochromia or ...
There may also be signs of anterior uveitis, such as miosis (small pupil), aqueous flare (protein in the aqueous humour), and redness of the eye. An axon reflex may be responsible for uveitis formation — stimulation of pain receptors in the cornea results in release inflammatory mediators such as prostaglandins, histamine, and acetylcholine.
