Clinical photographs and conjunctival histopathology. (A, B) Clinical photographs of retroprosthetic membrane. The arrows indicate the inferior edge of the membrane. (C, D) Multiple locules (L) of dissolved-out silicone oil in the conjunctiva display varying sizes. (E) Higher power photomicrograph of a locule demonstrating mononucleated, eosinophilic, histiocytic epithelioid cells including a giant cell (arrow). (F) CD68 for histiocytes stains the lining cells of the locules. The more intensely stained cells (arrows) are multinucleated giant cells. (B, D, E,) Hematoxylin and eosin, ×100, ×200, and ×600. (F) Immunoperoxidase reaction, diaminobenzidine chromogen, and hematoxylin counterstain, ×200.
