Uveitic glaucoma patients are at significantly higher risk for visual field loss in the long term compared to patients who only have uveitis. Patients with uveitic glaucoma also experience a particularly high burden of care. Signs and symptoms
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. An ophthalmologist may be able to observe the main sign of active noninfectious anterior uveitis, which is the presence of immune cells (anterior chamber cells, or ACCs) floating within the anterior segment of the eye (see "Noninfectious anterior uveitis" in Diagnosis section). The ophthalmologist also may observe peripheral anterior synechiae (PAS), or adhesions between the iris and trabecular meshwork, the tissue responsible for draining aqueous humour from the eye.Patients with uveitis who also experience symptoms of glaucoma may have uveitic glaucoma. In an eye with uveitic glaucoma, the following glaucoma signs may be observed: elevated intraocular pressure, scotomas in the field of vision, defects in the fiber layer of the retinal nerve, and/or excavation (a regional deformation or depression of the optic nerve). Pupillary blocks, or the obstruction of "the flow of aqueous humor from the posterior chamber to the anterior chamber" due to a "functional block between the pupillary portion of the iris and the lens" may also be detected.
Because of this, 80% of uveitis experts report that glaucoma surgeries for uveitic glaucoma patients are likely to fail. Surgery in an eye with uveitis is associated with a higher complication rate, and in some cases surgeries such as valve implantation are too complicated to perform. Prognosis for  uveitic glaucoma patients
About 30% of uveitis patients also develop uveitic glaucoma. Uveitic glaucoma patients are at significantly higher risk for visual field loss in the long term (>5 years) compared to patients who only have uveitis. A patient who only has glaucoma (without uveitis) will, on average, become blind in one eye within 20 years of glaucoma onset. This is especially devastating given that the majority of uveitic glaucoma patients are diagnosed with uveitis at a relatively young age (in their thirties). Thus developing glaucoma at a young age and the cumulative damage of uveitis flare-ups put these patients at high risk of losing their eyesight. The burden of care for uveitis glaucoma patients is also higher than that of uveitis patients without glaucoma. On average, doctors report 60% more visits from uveitic glaucoma patients than non-glaucomatous uveitis patients. Doctor visits are 40% longer for patients with uveitic glaucoma than for uveitis patients without glaucoma. Epidemiology
According to epidemiological studies, the prevalence of uveitis is estimated at 115-316 occurrences in 100,000 people. About 30% of patients with non-infectious anterior uveitis also develop glaucoma. Accordingly, 34-94 people in every 100,000 patients with uveitis will develop glaucoma.
