Safety and Biocompatibility of a New High-Density Polyethylene-Based Spherical Integrated Porous Orbital Implant: An Experimental Study in Rabbits

Figure 3

Histological evaluation under polarized light at 90 days after orbital implantation. Orbital implants MEDPOR, OCULFIT I, and OCULFIT II appeared as birefringent intraocular solid material adjacent to the internal surface of the sclera ((a), (b)). Birefringent cylindrical units were present in the peripheral adipose tissue (c). Scale bars: 20 µm ((a), MEDPOR; (c)) and 50 µm ((b), OCULFIT II).
