Episcleritis

Episcleritis is a common, benign, self-limiting inflammatory condition affecting the episclera, the thin layer of vascularized connective tissue between the conjunctiva and the sclera. It is characterized by sudden-onset redness and mild ocular discomfort.

Most cases (approx. 70%) are idiopathic. When systemic, it is frequently associated with autoimmune or inflammatory disorders, including rheumatoid arthritis, inflammatory bowel disease, systemic lupus erythematosus, and polyarteritis nodosa. Lifestyle factors include stress and hormonal fluctuations.

The condition involves localized inflammation of the episcleral vessels. It is generally thought to be a hypersensitivity reaction. Pathologically, it presents as perivascular lymphocytic infiltration, edema, and vascular dilation without the deep scleral collagen degradation seen in scleritis.

It occurs primarily in young to middle-aged adults, with a female predilection (roughly 2:1). Prevalence is higher in patients with pre-existing systemic autoimmune diseases.

• Female gender
• Personal history of autoimmune disease
• High-stress environments
• Smoking (less common link compared to scleritis)

A. Early Symptoms

• Mild foreign body sensation


• Transient eye redness


• Episodic mild pruritus B. Common Symptoms


• Sectoral or diffuse hyperemia


• Ocular burning or stinging


• Mild tenderness to palpation C. Advanced Symptoms


• Formation of a discrete, mobile, elevated nodule (in nodular type)


• Increased frequency of recurrence D. Emergency Symptoms


• Severe pain (suggests progression to scleritis)


• Significant decrease in visual acuity


• Photophobia or diplopia

Inspection reveals sectoral or diffuse redness. Topical phenylephrine (2.5%) induces blanching of the episcleral vessels, which is a hallmark finding distinguishing it from scleritis.

A. Clinical Assessment: Slit-lamp biomicroscopy.
B. Laboratory Testing: Only indicated if recurrence is frequent or systemic disease is suspected.
C. Imaging Studies: Generally not required.
D. Functional Tests: Visual acuity testing.
E. Biopsy Findings: Rare; used only if malignancy is suspected.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Scleritis, conjunctivitis, subconjunctival hemorrhage.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Screen for underlying systemic inflammatory disease.
Expected Findings: Normal in primary cases.
Interpretation: Elevated ESR or CRP may suggest systemic associations.

Optical Coherence Tomography (OCT)
Purpose: To assess depth of inflammation.
Typical Findings: Superficial involvement.
Clinical Importance: Rules out scleral thinning.

• Scleritis: Characterized by severe pain and lack of blanching with phenylephrine.
• Conjunctivitis: Involves diffuse injection with discharge.

Rarely progresses to scleritis; generally no permanent visual impairment.

A. Lifestyle Modifications: Cold compresses, artificial tears.
B. Preventive Measures: Managing systemic inflammation.
C. Medical Treatment: Topical lubricants, NSAIDs (e.g., ketorolac), or mild topical steroids (e.g., fluorometholone).
D. Surgical Treatment: None required.
E. Interventional Procedures: None.
F. Rehabilitation: None.
G. Emergency Management: Refer if pain increases or vision worsens.

Excellent; self-limiting within 1–3 weeks. Recurrences are common.
