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.
Posterior synechia can be observed in cases of anterior uveitis secondary to severe to moderate bacterial keratitis. [2] Posterior synechia also cause glaucoma, but with a different mechanism. In posterior synechia, the iris adheres to the lens, blocking the flow of aqueous humor from the posterior chamber to the anterior chamber.
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 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.

The crystalline lens inside the human eye has been implicated as a causative factor in many forms of glaucoma. Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens. It is a type of secondary glaucoma.

Drug-induced cysts are related with the use of miotics or latanoprost but can get smaller after stopping inducing the drug. [6] Uveitic cysts can arise when the eye is or has been inflamed. [7] Tumor-induced secondary cysts are caused by a tumor. [8] The rarest iris cyst is the parasitic cyst, which can develop with the presence of a parasite. [2]
