Uveitis

Uveitis refers to inflammation of the uveal tract—the middle, pigmented layer of the eye comprising the iris, ciliary body, and choroid. It is a spectrum of inflammatory conditions that can lead to permanent vision loss if untreated. Classification is based on anatomical location: anterior, intermediate, posterior, or panuveitis.

Etiology includes infectious agents (e.g., Herpes simplex, Toxoplasmosis, Tuberculosis), autoimmune systemic diseases (e.g., Sarcoidosis, Ankylosing spondylitis), and idiopathic causes. Genetic predisposition is linked to the HLA-B27 antigen.

Inflammation occurs when the blood-aqueous barrier is disrupted, allowing protein and inflammatory cells to infiltrate the aqueous humor or vitreous cavity. This immune-mediated response involves T-lymphocyte activation, cytokine release, and breakdown of the uveal vasculature, potentially leading to exudation, scar tissue formation, and secondary ocular hypertension.

Uveitis affects individuals of all ages, with a peak incidence in the 20–50 age demographic. It is a leading cause of preventable blindness, accounting for approximately 10-15% of blindness cases in developed nations.

• HLA-B27 genetic profile
• Autoimmune conditions (Behcet’s, JIA)
• History of ocular trauma
• Immunocompromised status
• Infections (Syphilis, HIV, Tuberculosis)

A. Early Symptoms

• Mild eye redness


• Blurred vision


• Mild photophobia B. Common Symptoms


• Ocular pain (aching)


• Perilimbal flush


• Increased sensitivity to light


• Floaters C. Advanced Symptoms


• Significant vision loss


• Irregular pupil shape


• Severe photophobia D. Emergency Symptoms


• Sudden, severe pain


• Acute reduction in visual acuity


• Persistent light flashes

Slit-lamp examination reveals "cells and flare" in the anterior chamber. Findings include mutton-fat keratic precipitates, iris synechiae, vitreous haze, and retinal vasculitis or chorioretinal lesions on fundoscopy. Intraocular pressure (IOP) may be elevated or decreased.

A. Clinical Assessment: Slit-lamp biomicroscopy and dilated fundus exam.
B. Laboratory Testing: Targeted based on anatomical location.
C. Imaging Studies: OCT and Fluorescein Angiography.
D. Functional Tests: Visual acuity and visual field testing.
E. Biopsy Findings: Generally only if malignancy is suspected.
F. Genetic Testing: HLA-B27 screening.
G. Differential Diagnosis: Conjunctivitis, acute glaucoma, scleritis.

Complete Blood Count
Type: Blood Test
Purpose: Identify systemic infection or inflammatory response.
Expected Findings: Elevated WBC.
Interpretation: Indicates systemic involvement.

Optical Coherence Tomography (OCT): Used to detect macular edema and monitor treatment response.
Fluorescein Angiography: Identifies vascular leakage, neovascularization, or capillary non-perfusion in the retina.

Conjunctivitis (no cells in anterior chamber), Acute Angle-Closure Glaucoma (steamy cornea, fixed pupil), Scleritis (deep, boring pain).

Cataracts, glaucoma, cystoid macular edema, retinal detachment, and permanent vision loss.

A. Lifestyle Modifications: UV protection, stress reduction.
B. Preventive Measures: Managing underlying systemic diseases.
C. Medical Treatment:

• Corticosteroids (Topical/Systemic): Anti-inflammatory (Prednisolone).


• Cycloplegics: To prevent synechiae (Atropine/Cyclogyl).


• Immunomodulators: (Methotrexate, Adalimumab).

Prognosis depends on the location and etiology. Early intervention usually leads to resolution, whereas chronic uveitis often leads to cataracts or glaucoma.

Screening for HLA-B27 patients with inflammatory back pain; early referral for patients with persistent red eye.
