“…Tanto a enucleação quanto a exenteração ocasionam uma órbita côncava e cosmeticamente inaceitável, principalmente em animais mesocefálicos e dolicocefálicos, os quais apresentam órbitas profundas (NASISSE et al, 1988). Para repor o vazio facial ocasionado por esses procedimentos cirúrgicos, compostos biologicamente inertes podem ser utilizados para melhoria da aparência estética (CHIN; MARGOLIN;FINGER, 2006;SPIESS, 2007;ARAF et al, 2010;BRANCO;GRUMANN JÚNIOR, 2012;MIYASHITA et al, 2013).…”

Purpose: To evaluate histologically the integration process of cellulose gel produced by Zoogloea sp when implanted into rabbits' eviscerated eyes. Methods: This experimental study employed 36 eyes of 18 rabbits subjected to evis ceration of their right eyes. The sclerocorneal bag was sutured and filled with biopolymer from sugar cane in the gel state. All animals were clinically examined by biomicroscopy until the day of their sacrifice which occurred on the 7 th , 30 th , 60 th , 90 th , 120 th , or 240 th day. The eyeballs obtained, including the left eyes considered controls were sent for histopathological study by optical macroscopy and microscopy. Tissue staining techniques used included hematoxylin-eosin, Masson trichrome (with aniline), Gomori trichrome, Van Gienson, Picrosirius red, and periodic acid-Schiff (PAS). Results:No clinical signs of infection, allergy, toxicity, or extrusion were observed throughout the experiment. The corneas were relatively preserved. Macroscopic examination revealed a decrease of ~ 8% in the volume of the bulbs implanted with the biopolymer. After cutting, the sclerocorneal bag was solid, compact, elastic, and resistant to traction, with a smooth and whitish surface, and showed no signs of necrosis or liquefaction. The episcleral tissues were somewhat hypertrophied. The histological preparations studied in different colors revealed an initial lymphoplasmacytic infiltration, replaced by a fibroblastic response and proliferation of histiocytes, along with formation of giant cells. Few polymorphonuclearneutrophils and eosinophils were also found. Neovascularization and collagen deposition were present in all animals starting from day 30; although on the 240 th day of the experiment the chronic inflammatory response, neovascularization and collagen deposition had not yet reached the center of the implant. Conclusion: In this model, the cellulose gel produced by Zoogloea sp proved to be biocompatible and integrated into the orbits. Morphometric, immunohistochemical and biodegradability studies should be performed in the future. Keywords
