[Surgical correction of conjunctival sac narrowing after orbital implantation using polyester fiber heart patches].

OBJECTIVE: To test the feasibility of correcting conjunctival sac narrowing following orbital implantation using polyester fiber heart patches instead of the skin autograft. METHODS: Twelve patients of conjunctival sac narrowing after orbital implantation (including 3 with orbital implant exposure) admitted in Nanfang Hospital between 2012 and 2016 received surgical correction of the conjunctival sac using polyester fiber heart patches. During the surgery, the central conjunctival sac was opened, the exposed area was covered with suitable polyester fiber heart patches, and the palpebral margin was sutured. RESULTS: Three months after the operation, 10 patients showed improved appearance after implantation of the prosthetic eye. Two patients received a second operation to remove the patches due to graft rejection and infections and skin autograft was implanted for reconstruction of the conjunctival sac. CONCLUSION: Polyester fiber heart patches are ideal materials for repairing Conjunctival sac narrowing and orbital implant exposure, but this approach is not suitable in cases of severe narrowing or occlusion of the conjunctival sac.

[A conjunctival pulling-back technique for treatment of serious symblepharon].

OBJECTIVE: To evaluate a new technique for treatment of the symblepharon caused by physical and chemical burn. METHODS: Thirty-eight patients with 40 eyes were undergoing the treatment. It was carried out to reconstruct the conjunctival fornix by pulling the remained conjunctive backward from the corneal limbus in serious stages. RESULTS: Thirty-eight patients (40 eyes) were treated with this technique, with the successful results of 13 patients (13 eyes) in 2 times, 19 patients (21 eyes) in 3 and 6 patients (6 eyes) in 1. Only one case was failure. CONCLUSION: The above mentioned technique could be a safe and effective way for treatment of symblepharen.
