title: Linear IgA disease.
abstract: OBJECTIVE
  A case of linear IgA disease is reported to alert ophthalmologists and physicians to this unusual cause of chronic cicatrizing conjunctivitis.
  
  
  METHODS
  Clinical records of a patient suffering from linear IgA disease were reviewed.
  
  
  RESULTS
  A 65-year-old woman with a complicated medical history experienced rapidly progressive chronic cicatrizing conjunctivitis leading to corneal perforation. Undiagnosed gingivitis and palatal ulceration had been present for 5 years prior to the onset of ocular symptoms and vitamin C deficiency had followed the consequent dietary restrictions. A diagnosis of linear IgA disease was made on conjunctival biopsy, which demonstrated linear deposits of IgA along the epithelial basement membrane. The perforation was managed successfully with a conjunctival pediculate flap. Control of the inflammation was achieved with systemic prednisolone and cyclophosphamide but at the expense of serious systemic side-effects.
  
  
  CONCLUSIONS
  Linear IgA disease causes progressive conjunctival cicatrization in many affected individuals. Although dapsone generally controls the inflammation, heavier systemic immunosuppression was required in this case. Involvement of skin or other mucosal surfaces may become symptomatic before the conjunctivitis, and physicians must be educated to refer patients for ophthalmological review on diagnosis. Conversely, ophthalmologists encountering ocular linear IgA disease should be aware of the possibility of other mucosal involvement requiring physician intervention.
