Primary localized conjunctival amyloidosis presenting with recurrence of subconjunctival hemorrhage
1Toronto Western Hospital, University Health Network, University of Toronto, Ontario, Canada.
Purpose:
To report the ocular presentation and histopathology of a patient with primary localized conjunctival amyloidosis.
Methods:
A 38-year-old woman presented with a recurrence of episodes of severe bilateral subconjunctival hemorrhage. Ocular examination revealed yellowish, marked folding and redundancy of the conjunctiva in the inferior cul-de-sac of each eye.
Results:
After two initial conjunctival biopsies that showed only chronic inflammation, a third biopsy revealed the presence of amyloid in the substantia propria of the conjunctiva.
Conclusion:
Primary localized conjunctival amyloidosis is rare and usually diagnosed histologically instead of clinically. Recurrence of subconjunctival hemorrhage may be the initial presentation. Evaluation for systemic diseases is advised, though the results of the examination are almost always negative.
