Scleritis

Scleritis is a severe, chronic, and potentially vision-threatening inflammatory disease involving the sclera (the white, fibrous outer coat of the eye). Unlike episcleritis, scleritis is characterized by deep-seated pain and significant inflammation that often heralds underlying systemic autoimmune disease.

Scleritis is largely considered an immune-mediated condition. Etiologies include systemic autoimmune diseases (rheumatoid arthritis, granulomatosis with polyangiitis, relapsing polychondritis), infectious causes (herpes zoster, Pseudomonas, tuberculosis, syphilis), and localized trauma or post-surgical complications.

The pathophysiology involves immune complex deposition or Type IV hypersensitivity reactions within the scleral collagen fibers. Inflammatory mediators (cytokines, prostaglandins) trigger localized vasodilation and edema. Chronic inflammation leads to the activation of fibroblasts, resulting in tissue thinning, necrosis, and scleral melting.

Scleritis is relatively rare, with an incidence of approximately 4.7 per 100,000 person-years. It typically affects adults aged 40–60 years and demonstrates a predilection for women, particularly in the context of associated connective tissue diseases.

• Rheumatoid arthritis (most common association)
• Wegener’s granulomatosis (granulomatosis with polyangiitis)
• Systemic lupus erythematosus
• Surgical trauma (e.g., strabismus or pterygium surgery)
• Infectious ocular history

A. Early Symptoms

• Mild ocular discomfort


• Localized redness


• Sensitivity to light B. Common Symptoms


• Boring, intense, deep ocular pain


• Pain radiating to the brow, temple, or jaw


• Blurred vision C. Advanced Symptoms


• Scleral thinning (bluish-hue)


• Vision loss


• Photophobia and tearing D. Emergency Symptoms


• Sudden, severe decrease in visual acuity


• Intense pain unresponsive to topical analgesics


• Visible globe perforation

Inspection reveals deep, violaceous redness. Palpation of the globe elicits extreme tenderness. Slit-lamp examination demonstrates scleral edema and vascular congestion.

A. Clinical Assessment: Slit-lamp biomicroscopy.
B. Laboratory Testing: Rule out systemic disease.
C. Imaging Studies: B-scan ultrasound or OCT.
D. Functional Tests: Visual acuity, intraocular pressure.
E. Biopsy Findings: Usually reserved for suspected malignancy.
F. Genetic Testing: Generally not indicated.
G. Differential Diagnosis: Episcleritis, uveitis, conjunctivitis.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Evaluate systemic inflammation
Expected Findings: Elevated ESR/CRP
Interpretation: Non-specific indicator of inflammation.

Ocular B-scan Ultrasound: Used to demonstrate "T-sign" (fluid in the sub-Tenon space) and scleral thickening. Essential for posterior scleritis diagnosis.

• Episcleritis: Differentiated by lack of severe pain and positive phenylephrine blanching test.
• Uveitis: Inflammation of the uveal tract, often presenting with anterior chamber cells.

• Scleromalacia perforans (scleral melting)
• Glaucoma
• Cataracts
• Retinal detachment
• Permanent vision loss

A. Lifestyle Modifications: UV protection.
B. Preventive Measures: Early treatment of systemic autoimmune conditions.
C. Medical Treatment:

• NSAIDs (e.g., Flurbiprofen) for mild cases.


• Systemic Corticosteroids (e.g., Prednisone) for severe inflammation.


• Immunomodulatory therapy (e.g., Methotrexate, Rituximab). D. Surgical Treatment: Scleral patch grafting for thinning.

Prognosis depends on the underlying systemic disease. Early intervention prevents globe rupture; however, recurrence is common.

Close monitoring of patients with known systemic autoimmune disorders (rheumatoid arthritis) by rheumatologists and ophthalmologists.

The following homeopathic remedies have been historically indicated for symptoms associated with Scleritis. Selection should be based on individualized symptom totality and constitutional assessment.
