Scleromalacia Occurring 50 Years after Strabismus Surgery.

Scleritis is a group of rare inflammatory diseases caused by an infectious or noninfectious aetiology. It has an incidence of 3.4 patients per 100 000 person-years [1]. It can be divided as anterior and posterior. Noninfectious anterior scleritis is caused by an autoimmune disease in up to 50% of cases, with rheumatoid arthritis and granulomatosis polyangiitis being the most common [1]. Surgeries can also induce it by excessive conjunctival manipulation and cauterisation [2]. It is classified as diffuse, nodular, necrotising with inflammation (called necrotising), or necrotising without inflammation (called scleromalacia perforans). Infectious anterior scleritis can be exogenous (post-traumatic or postsurgical) or endogenous (caused by a systemic infectious disease such as syphilis or tuberculosis) [1], [3]. The treatment depends on the aetiology and the extensive inflammatory and infectious disease workup.
