Use of intraocular acrylic resin prosthesis. Experimental study in rats
AbstractThe ocular globe was eviscerated in 32 Wistar rats, divided in four groups (A, B, C, D) of eight animals each. Acrylic resin prosthesis was implanted into the corneoscleral membrane in five animals of each group. The other three did not receive the prosthesis. The methylmetacrylate sphere was manufactured and autoclaved. The animals from A, B, C and D groups were euthanized at 7, 15, 30 and 90 days after surgery, in the same order, and the orbital content was submitted to histopathological examination. A granulomatous inflammatory response surrounded the prosthesis and inflammatory edema in the cornea was observed mainly in the animals of A and B groups. The volume of the anophthalmic cavity was replaced in all animals that received the prosthesis, but not in the animals that did not received it. It was concluded that intraocular prosthesis of acrylic resin is a cosmetic alternative for correction of the defect produced by the lost of the ocular globe.
