Quick Summary

Episcleritis is a benign inflammation of the episclera, the thin layer of tissue covering the sclera (the white part of the eye). Unlike scleritis, which affects the deeper sclera and can be severe and painful, episcleritis is typically mild and self-limiting.12

It often causes redness of the eye with or without slight tenderness. While episcleritis usually improves without treatment, anti-inflammatory medication may be used in more severe cases. It rarely occurs with underlying systemic diseases, making it distinct from scleritis, which can be associated with conditions like rheumatoid arthritis or tuberculosis.12
