[Isolated and primary palpebro-conjunctival amylosis. Apropos of 2 cases]

Ocular amyloidosis a an uncommon condition and conjunctival involvement rarely occurs, representing 15% of all ocular localizations. Clinical manifestations show a polymorphism requiring a histological diagnosis. Based on two cases of primary isolated conjunctivo-palpebral amyloidosis, we discuss the different ocular sites. The first case involved false ptosis, a conjunctival infiltration and a lower eyelid tumefaction; all located in the left eye. The second case had ptosis, a right lower eyelid tumefaction with ectropion and esthetic damage. Amyloidosis was confirmed at histologic examination of the conjunctival mucous after a special congo red coloration. In order to affirm the isolated conjunctival localization, it is necessary to eliminate another amyloidis site. The treatment was surgical with excision and cure of ptosis. Ocular amyloidosis is a rare condition with polymorphism manifestations. Confirmation is histological. The greatest difficulty is management due to disease recurrence.
