Background: Severe penetrating ocular trauma often results in persistent hypotony either due to direct trauma to the ciliary body or to its secondary anterior PVR overgrowth. The treatment options include permanent silicone oil endotamponade, but corneal contact of silicone oil leading to corneal opacification is a common problem.
Methods: In this presentation we will show clinical examples of posttraumatic hypotony and our treatment attempts. We used iris diaphragms in combination with silicone oil or repeated injections of slow resorbing viskoelastics (Healon).
Results: With iris diaphragms silicone oil could be kept in the posterior segment in about half of the cases. Repeated injections of slow resorbing viskoelastics is an alternative and can stabilize intraocular pressure for days to weeks. It can also be performed in silicone oil filled eyes. An new alternative could be a silicone balloon which were are currently testing in an animal model.
