Bowman in 1849 first described Mooren’s ulcer of the cornea which has also been called chronic serpiginous ulcer and ulcer rodens [1]. Then, in 1867, Mooren provided details of cases of the condition in a publication that established Mooren’s corneal ulcer as a distinct clinical entity [1]. Formal guidelines for the diagnosis of Mooren’s ulcer have not been developed [2]. Though amongst clinicians and in the literature, there is general agreement that the condition is characterised by a painful, relentless, chronic ulceration of the cornea that begins in the corneal periphery with progression circumferentially and centrally [3]. Mooren’s ulcer has a variable presentation in terms of demographics, severity and disease progression. Medical and/or surgical management is required to heal the ulceration, to prevent vision loss from scarring and astigmatism and to avoid complications including corneal perforation, uveitis and infection.
