Non-resorbable endotamponades like silicone oil are tools in retinal detachment surgery. Problems can arise from emusification or from silicone oil prolaps into the anterior chamber in hypotonic eyes. We developed a balloon containment system for liquid endotamponades to address the above mentioned problems.
Silicone foils with polyethylene glycol (PEG) coating were shown to be biocompatible (ARVO 2007 poster 5477). We developed several balloon models from this silicone material. Implantation and explantation techniques as well as intraoperative handling were tested in porcine cadaver eyes after lens and vitreous removal.
Implantation was possible through a 4 mm pars plana sclerotomy. Fundus viewing was excellent with the balloon filled with balanced salt solution or silicone oil.
The balloon system could be useful in hypotonic eyes requiring silicone oil tamponade. Currently we are conduction long term implantation experiments in a porcine animal model. First results will be available at the ARVO meeting.
