Study on Fibrovascular Ingrowth into the Intraocular Implant, Medpor(R)

ABSTRACT

PURPOSE: We investigated the effects of bFGF/Sucralfate/Hydron suspension and hyperbaric oxygen on fibrovascular ingrowth into porous implants materials. METHODS: Eight rabbits underwent bilateral abdominal incision through which porous orbital disc-shaped implants were inserted between abdominal muscles. These implants were either uncoated or coated with suspension of bFGF/Sucralfate/Hydron. Hyperbaric oxygen therapy was performed on 4 selected rabbits for 5 days or 10 days. Implants were harvested after 3 days, 1 week, 2 weeks and 4 weeks. RESULTS: Enhanced fibrovascular ingrowth was shown in bFGF/Sucralfate/Hydron or hyperbaric oxygen treated implants. bFGF/Sucralfate/Hydron treated implants demonstrated more fibrovascularization than hyperbaric oxygen treated implants. CONCLUSIONS: Simultaneous therapy of bFGF/Sucralfate/Hydron and hyperbaric oxygen showed more fibrovascularization than separately treated implants.
