PURPOSE: The aim of this work was to study the clinical presentation, management and outcomes of orbital and adnexal amyloidosis.

METHODS: This retrospective analysis included all the patients diagnosed with orbital and adnexal amyloidosis between January 1990 and December 2019. Positive staining with Congo Red and apple-green birefringence on polarized light microscopy established the diagnosis. Data analyzed included demographic profile, varied presentations, management, and outcome.

RESULTS: Thirty-three eyes of 26 patients were included. The male:female ratio was 1:1. The mean age of the study population was 42.6 ± 16 years. The median duration of symptoms was two years. Unilateral involvement was seen in 19 eyes (right = 11, left = 8). The most common presenting feature was acquired ptosis. Eyelid was the most commonly affected site followed by orbit and conjunctiva. Two patients had systemic involvement in the form of multiple myeloma and lymphoplasmacytic lymphoma. Complete excision was done in seven (26.9%) cases while 19 (73.1%) cases underwent debulking. Three patients underwent ptosis surgery. The median duration of follow-up was 1.5 years. Three cases had recurrence and underwent repeat surgery.

CONCLUSION: Orbit and adnexa is a rare site for amyloidosis. It is usually localized; however it can occur as a part of systemic amyloidosis. Eyelid is the most common site of involvement and patients usually present as eyelid mass or ptosis. Complete excision is difficult and most of the patients usually undergo debulking surgery. All patients should undergo screening for systemic amyloidosis.
