Abstract
Episcleritis is a relatively benign condition, which is distinctly different from scleritis. It may present as either the simple variety, which is much more common, or as nodular episcleritis. Simple episcleritis may be either sectoral or diffuse and typically has an acute onset with minimal discomfort. Nodular episcleritis usually has an insidious onset and is more uncomfortable. The injection of episcleritis is typically brick red as opposed to the violaceous hue of scleritis. Most cases of episcleritis are idiopathic, but recurrent or persistent disease should be evaluated for a systemic etiology. Treatment of mild cases is usually unnecessary. Recurrences or nodular episcleritis should usually be treated with either oral nonsteroidal antiinflammatory drugs or topical steroids.
