Answer

Peripheral ulcerative keratitis (PUK) is uncommon. RA has been reported as the most common collagen vascular disorder that causes PUK, accounting for 34% of noninfectious PUK. [6, 7, 8] PUK may be the initial manifestation of WG and PAN. PUK is rare in patients with RP; only 2 of 112 patients with RP were reported to develop PUK in a clinical review study. [9] PUK has also been reported to be associated with SLE, although this is uncommon. [3, 10] Mooren ulcer is a rare local autoimmune disease associated with PUK, with only 287 cases reported in the world literature, although some of these cases may have been the presenting manifestation of an occult systemic disease rather than true Mooren ulcer.
