A Rare Presentation: Bilateral Necrotizing Scleritis in Primary Sjögren's Syndrome.

PURPOSE

We report a rare and challenging case of bilateral necrotizing scleritis in primary Sjögren's syndrome (pSS).

METHODS

Retrospective case report.

RESULTS

A 72-year-old diabetic, hypertensive female patient presented with sudden onset of painful red left eye and was noted to have a corneal ulcer with severe thinning. She was managed with topical fortified antibiotics and tissue glue and bandage contact lens. During subsequent follow-ups, she developed necrotizing scleral melts in both eyes. On investigations, antinuclear antibodies were positive in a dilution of 1:160 with 2+ speckled pattern, with antinuclear antibody line immunoassay showing anti SS-A/ Ro52 positive. In view of rapidly developing scleral thinning and impending perforation, she was started on intravenous methylprednisolone 1 g/day for 3 days, along with steroid-sparing immunomodulatory therapy (mycophenolate mofetil 500 mg twice a day). She showed a rapid response to therapy and is currently stable on tapering oral steroids and mycophenolate mofetil.

CONCLUSION

This case underscores the unique presentation of pSS, characterized by bilateral necrotizing scleritis. The favorable outcome was attained through prompt immunosuppressive intervention and a collaborative, multidisciplinary approach. Further, this case report addresses a gap in the existing literature concerning pSS-related scleritis. It also emphasizes the crucial role of a rheumatologist in the comprehensive management of this condition.
