Anterior Uveitis

Anterior uveitis is an inflammatory condition affecting the anterior uvea, which consists of the iris, ciliary body, and anterior chamber angle. 

Clinical Presentation:

• Acute Signs are: 1) Blepharospasm (squinting) and ocular pain.

2) Hyperemia: Redness in the episcleral or conjunctiva.

3) Corneal Changes: Diffuse corneal edema.

4)Pupillary Changes: Miosis (constricted pupil).

5) Anterior Chamber Content: Aqueous flare (protein/cells), fibrin, hypopyon (pus), or hyphema (blood).

• Chronic Signs are: Synechiae: Adhesions (anterior or posterior), Dyscoria: Irregular pupil shape and Keratic precipitates and secondary cataracts or glaucoma.

Underlying Etiology (Causes): 

1) Primary Ocular Disorders:

• • Blunt or penetrating trauma.

  • Cataracts or lens instability.

  • Neurogenic reflex originating from corneal ulceration.

  • Intraocular neoplasia.

2) Systemic Diseases: Should be strongly suspected if the condition is bilateral (affecting both eyes).

• • Infectious diseases.

  • Autoimmune diseases.

  • Metastatic neoplasia.

Management and Treatment: 

• Anti-inflammatory Therapy: Topical or systemic corticosteroids or NSAIDs.

• Mydriatics: Topical agents used to dilate the pupil.

• Targeted Therapy: Additional drugs to treat specific underlying etiologies identified during the workup.

Prognosis and Long-term Complications:

• General Prognosis: Depends heavily on identifying and treating the underlying cause.

• Challenges: Chronic or recurrent cases (e.g., uveodermatologic syndrome) are difficult to manage.

• Potential Sequelae:

  • Secondary glaucoma or cataracts.

  • Phthisis bulbi (shrunken, nonfunctional eye).
