What Is Non-Granulomatous Anterior Uveitis?

Non–granulomatous anterior uveitis is inflammation of the iris and ciliary body characterized by fine inflammatory cells and small keratic precipitates, without the large granulomatous deposits seen in granulomatous uveitis. It often has an acute onset with redness, pain, and photophobia. Many cases are idiopathic, but it is frequently associated with HLA–B27 related diseases, viral infections, or trauma. Because it primarily affects the front of the eye, prompt treatment usually leads to good recovery, though recurrences are common.

Clinical Features and Examination

Patients typically present with unilateral red eye, aching pain, light sensitivity, and blurred vision. On slit lamp examination, clinicians see ciliary flush, cells and flare in the anterior chamber, and fine nongranulomatous keratic precipitates on the corneal endothelium. The pupil may be slightly constricted and sluggish, and posterior synechiae can form if inflammation is strong. Intraocular pressure can be low initially and later become elevated in some cases. The vitreous and posterior segment are usually quiet.

Common Causes and Associations

Non–granulomatous anterior uveitis is often linked with HLA–B27 associated spondyloarthropathies such as ankylosing spondylitis, reactive arthritis, and psoriatic arthritis. Herpes simplex and varicella zoster virus can cause unilateral recurrent uveitis with a similar nongranulomatous appearance, often with sectoral iris atrophy or pressure spikes. Trauma, intraocular surgery, and idiopathic immune reactions are other causes. A careful systemic review and targeted testing help identify underlying disease when present.

Diagnosis and Workup

Diagnosis is mainly clinical, based on the anterior uveitis pattern and absence of granulomatous signs such as mutton fat keratic precipitates or iris nodules. In recurrent or bilateral cases, laboratory evaluation for HLA–B27, syphilis, sarcoidosis, and other systemic conditions is often performed. Viral etiologies are suspected based on history and characteristic findings and sometimes confirmed with aqueous humor analysis. The workup is tailored to age, systemic symptoms, and uveitis course.

Treatment and Prognosis

Treatment centers on topical corticosteroid drops to reduce inflammation and cycloplegic agents to relieve pain and prevent synechiae. Frequency of drops is adjusted based on response, with a gradual taper once the eye quiets. In viral associated cases, antiviral therapy is added. Systemic immunomodulatory treatment may be needed for frequent recurrences or strong systemic associations. Prognosis is generally good for vision, but repeated attacks can lead to cataract, glaucoma, or macular edema, so long term follow up is important.

FAQs About Non-Granulomatous Anterior Uveitis

Is this type of uveitis contagious?

No, the inflammation itself is not contagious, though viral triggers can sometimes be.

Will one episode of anterior uveitis come back?

Many patients experience recurrences, especially when HLA–B27 or viral causes are involved.

Do eye drops cure the underlying disease?

Drops control ocular inflammation, but systemic conditions such as arthritis need separate management.

Can non-granulomatous anterior uveitis cause permanent vision loss?

Most people recover well with treatment, but repeated or severe attacks can lead to complications that threaten vision.
