IgG4-related Disease Presenting as Isolated Cicatrising Conjunctivitis.

A 46-year-old male presented with a 12-month history of trichiasis and was found to have significant, progressive cicatrization of the tarsal conjunctiva causing entropion of the upper and lower eyelids. A biopsy confirmed the diagnosis of IgG4-related cicatrizing conjunctivitis in the absence of any other organ involvement, a previously unreported manifestation of this immune-mediated disease.
