Abstract
Episcleritis is the inflammation of the thin, loose, highly vascular connective tissue layer that lies between the conjunctiva and sclera. Incidence is less than 1/1000. It is more common in women and those between 40 and 50 years of age. Most cases are idiopathic. It is classified into simple and nodular. Most attacks resolve within 1-3 months. The nodular type tends to be more recurrent and painful. It presents with acute onset of redness, lacrimation, and photophobia. The diagnosis of is essentially clinical, and eye pain or tenderness should raise the concern for scleritis. Ophthalmological referral is recommended to rule out scleritis. Bloodwork to diagnose associated systemic rheumatological disease may be helpful. Cold compresses and artificial tears provide symptomatic relief. Topical nonsteroidal anti-inflammatory drugs (NSAIDs) and steroids are used for persistent symptoms. Rarely, systemic steroids may be necessary. Immunosuppressive treatment to control an underlying autoimmune disorder is the last resort for resistant cases.
