A 68-year-old-man was seen in consultation for a suspicious medial canthal lesion that developed over a 2-year period. The raised, nodular lesion was skin colored, had a raised pearly border and a central depression with superficial crusting. Basal cell carcinoma was suspected and an excisional biopsy was performed.

Methods: Nine New Zealand white rabbits underwent enucleation of one eye followed by implantation of either a 12-mm Brazilian synthetic HA implant or a 12-mm BioEye, wrapped in polyglactin 910 mesh. Magnetic resonance imaging was performed to assess fibrovascular ingrowth 4, 8, and 12 weeks after implantation.
Purpose: To analyze a mammalian hydroxyapatite (HA) implant known as the Molteno M-Sphere, recently approved by the Food and Drug Administration of the United States.
Methods: The authors examined the implant macroscopically, with chemical analysis (x-ray powder diffraction, x-ray fluorescence spectrophotometry), and microscopically with scanning electron microscopy. Animal implantation of six Molteno M-Spheres was carried out in six adult male New Zealand albino rabbits.
The bioceramic orbital implant: a new generation of porous implants.
Ophthalmic Plast Reconstr Surg
September 2000
Purpose: The authors describe a new generation of porous orbital implant made of aluminum oxide (Al2O3) and compare it with the hydroxyapatite orbital implants (Bio-Eye and FCI hydroxyapatite).
Methods: The authors examined the new implant macroscopically, with chemical analysis and microscopically with scanning electron microscopy. Animal implantation studies were performed using six adult male New Zealand albino rabbits.
Objective: To describe the histopathologic features of two cases of epithelioid hemangioma occurring in the orbit and to distinguish this condition from Kimura's disease and from other vascular lesions of proliferated endothelium.
Design: Two interventional case reports.
Intervention: Treatment consisted of orbitotomy with excision of the tumor.
