Acute anterior uveitis (AAU) is a sudden inflammation of the front part of the uvea, specifically the iris (colored ring of the eye) and the ciliary body (which produces fluid and helps focus the lens). In AAU, immune cells infiltrate the anterior chamber—the space between the cornea and the iris—leading to pain, redness, and light sensitivity. This inflammation can cause proteins and white blood cells to settle on the inner surface of the cornea (keratic precipitates) and in severe cases form a visible fluid level (hypopyon). Prompt diagnosis and treatment are essential to prevent complications such as synechiae (adhesions between the iris and lens), cataract formation, secondary glaucoma, and permanent vision loss BMJ Best PracticeCleveland Clinic.
Acute anterior uveitis (AAU) is inflammation of the front (anterior) portion of the uveal tract, specifically the iris and ciliary body, and is often referred to as iritis when limited to the iris. In AAU, inflammatory cells leak into the aqueous humor, causing pain, redness, and light sensitivity. The onset is typically sudden, developing over hours to days, and without prompt treatment, AAU can lead to complications such as synechiae (iris adhesions), cataract formation, and glaucoma ScribdEyeWiki.
Patients with AAU usually present with an acutely painful, red eye accompanied by intense photophobia (light sensitivity) and sometimes blurred vision or floaters. These symptoms reflect the breakdown of the blood–aqueous barrier and the presence of inflammatory cells (“flare” and “cells”) in the anterior chamber PMCMayo Clinic.
By definition, “acute” refers to an episode lasting less than three months, often with a rapid onset over hours to days. If inflammation recurs after a symptom-free period of at least three months, it is termed “recurrent.” Chronic anterior uveitis persists beyond three months. AAU accounts for approximately 50–90% of all uveitis cases in Western countries and 28–50% in Asia, most commonly affecting adults between 20 and 60 years of age WikipediaMayo Clinic.
Types of Acute Anterior Uveitis
1. Idiopathic Acute Anterior Uveitis
About half of AAU cases have no identifiable underlying cause and are labeled idiopathic. Patients typically present with classic symptoms—eye pain, redness, and photophobia—without systemic disease or infection. Thorough evaluation often fails to reveal an associated disorder, yet the inflammation responds well to topical steroids and cycloplegic agents Mayo Clinic.
2. HLA-B27–Associated Acute Anterior Uveitis
HLA-B27 positivity is strongly linked to AAU. These patients often have unilateral, non-granulomatous inflammation that alternates between eyes. There is a male predominance and frequent recurrences. HLA-B27–associated AAU may occur alone or in association with spondyloarthropathies such as ankylosing spondylitis and reactive arthritis Wikipedia.
3. Infectious Acute Anterior Uveitis
A variety of pathogens can directly invade or trigger autoimmune responses in the anterior uvea. Common infectious causes include herpes simplex virus (HSV), varicella-zoster virus (VZV), cytomegalovirus, syphilis, tuberculosis, toxoplasmosis, and Lyme disease. Infectious AAU often requires both antimicrobial therapy and anti-inflammatory treatment WikipediaNCBI.
4. Granulomatous Acute Anterior Uveitis
Characterized by large, greasy-appearing keratic precipitates and nodules on the iris surface (Busacca or Koeppe nodules), granulomatous AAU suggests underlying systemic disease—such as sarcoidosis, tuberculosis, or syphilis—and often follows a more indolent course. Management targets both inflammation and the underlying cause Wikipedia.
5. Nongranulomatous Acute Anterior Uveitis
The most common form of AAU, nongranulomatous cases present with fine, stellate keratic precipitates and pronounced ciliary injection. They tend to be idiopathic or HLA-B27–related, with a sudden onset and rapid response to topical steroids Wikipedia.
6. Posner–Schlossman Syndrome (Glaucomatocyclitic Crisis)
This variant combines mild anterior uveitis with markedly elevated intraocular pressure (IOP). Patients may report minimal pain despite high IOP, and small white keratic precipitates are seen. Treatment focuses on lowering IOP and controlling inflammation Mayo Clinic.
7. Fuchs Heterochromic Iridocyclitis
Although often chronic, Fuchs heterochromic iridocyclitis can present with acute flare-ups. It causes mild inflammation with diffuse, small keratic precipitates, heterochromia (difference in iris color), and cataract development. Unilateral involvement is most common, and vision may gradually decline over time Wikipedia.

Do keep a clean environment and hands when administering drops. Avoid touching the dropper tip to any surface.
Do protect your eyes from bright light with sunglasses. Avoid direct sun or high-intensity lamps.
Do maintain regular follow-up appointments. Avoid self-adjusting medication strength or frequency.
Do use lubricating artificial tears as needed. Avoid over-the-counter steroid drops without supervision.
Do rest your eyes during acute flares. Avoid strenuous activities that strain vision.
Do report systemic symptoms (joint pain, rash). Avoid assuming eye inflammation is isolated.
Do follow dietary supplement guidelines from your physician. Avoid megadoses without medical advice.
Do practice relaxation and stress-management techniques. Avoid high-stress situations when possible.
Do monitor intraocular pressure as directed. Avoid ignoring new symptoms of increased pressure (headache, halos).
Frequently Asked Questions
What causes acute anterior uveitis?
AAU can be idiopathic or linked to autoimmune diseases (e.g., ankylosing spondylitis), infections (herpes simplex), or medication reactions. Many cases remain without an identified cause.How is AAU diagnosed?
A slit-lamp examination by an ophthalmologist reveals inflammatory cells and flare in the anterior chamber; intraocular pressure and fundus examination help rule out complications.Is AAU contagious?
No. Non-infectious AAU is not contagious. Infectious causes (e.g., herpes) can spread if ulcers are present, but typical AAU is immune-mediated.How long does an acute episode last?
With prompt treatment, most AAU episodes resolve in 4–6 weeks. Untreated, inflammation may persist or recur.Can AAU cause permanent vision loss?
If complications—such as glaucoma, cataract, or macular edema—develop and are untreated, permanent vision impairment can occur.What tests are needed?
Beyond slit-lamp exam, blood tests for HLA-B27, infectious serologies, and imaging (ocular ultrasound, OCT) may be ordered to identify systemic associations.Can lifestyle changes prevent recurrence?
Yes. Stress reduction, UV protection, and early recognition of systemic disease flares can lower recurrence risk.When are systemic medications needed?
If inflammation is bilateral, chronic, or refractory to topical therapy, systemic corticosteroids or immunosuppressants (methotrexate) are indicated.Are injections into the eye ever used?
Periocular or intravitreal steroids may be used in severe cases to deliver high drug concentrations with fewer systemic effects.Is AAU hereditary?
There is no direct inheritance pattern, but HLA-B27 positivity can run in families, increasing risk.Can children get AAU?
Yes, children—often in association with juvenile idiopathic arthritis—can develop AAU, requiring tailored therapy.How often should I have eye exams after AAU?
Typically every 1–2 weeks during active inflammation, then every 3–6 months once quiescent.Can contact lenses be worn after AAU?
Only after complete resolution and under ophthalmologist guidance, as lenses can irritate the inflamed eye.Are there alternative therapies?
Complementary approaches (e.g., acupuncture, herbal supplements) may help symptomatically but should not replace medical treatment.What is the long-term outlook?
With timely, appropriate therapy and monitoring, most patients maintain good vision, though some will experience recurrent episodes requiring ongoing management.
