Corneal patch graft for the repair of late- onset hypotony or filtering bleb leak after trabeculectomy: a new surgical technique. Repair of the filtering bleb using only conjunctiva reconstruction often fails when deeper tissue structures do not provide sufficient outflow resistance.
Here, we present a technique that uses anterior stromal lamellae left over from donor corneas used for descemet stripping automated endothelial keratoplasty procedures as patch grafts to repair the scleral tissue wound as a way to treat ocular hypotony. MATERIALS AND METHODS: We describe a new surgical technique to reconstruct the outflow resistance of melted trabeculectomy scleral flaps and present the course of 5 cases of severe hypotony treated using this technique. RESULTS: All 5 patients suffered from severe hypotony several years after trabeculectomy with antiproliferative agents. Multiple surgical and nonsurgical attempts to treat hypotony had failed. Lamellar corneal tissue was used as a patch graft to replace the weakened sclera near the site of the earlier trabeculectomy. This procedure successfully reversed hypotony in all cases. During the follow- up periods of at least 9 months, no recurrences of bleb leak or hypotony were observed.
Intraocular pressure (IOP) remained controlled with topical IOP- lowering treatment in 4 cases. In 1 case, a glaucoma drainage implant was used to control IOP. CONCLUSIONS: The use of lamellar corneal donor tissue to restore scleral outflow resistance is a safe and effective treatment for severe hypotony after mitomycin C- assisted trabeculectomy with or without filtering bleb leaks.
