ABSTRACT

Purpose: To demonstrate the reliability of conjunctival biopsy analyzed by direct immunofluorescence (DIF) and supplemented with avidin-biotin complex immunoperoxidase (ABC) in diagnosing oMMP, and report therapy response in biopsy-positive patients, particularly when previously biopsy-negative elsewhere.

Methods: Retrospective outcomes review of 136 consecutive patients after conjunctival biopsy for suspected oMMP.

Results: Among 136 patients, 66% were diagnosed with oMMP by DIF and 13% via supplemental ABC immunoperoxidase. Sensitivity increased from 79.6% with DIF to 95.6% with supplemental ABC. Among 57 biopsy-positive patients, 77% were in remission at 1-year follow-up and 88% after 2 years. Of 34 previous biopsy-negative but now biopsy-positive patients with a 2-year follow-up, 91% achieved remission, including all 16 diagnosed via DIF and ABC.

Conclusion: Conjunctival biopsy analyzed by histopathology and DIF supplemented by ABC has high reliability for diagnosing oMMP and is a useful tool to use before starting long-term immunomodulatory therapy in a patient with suspected oMMP.
