Purpose: To describe the use of the amniotic membrane for the repair of the exit wound of a perforating injury involving the retina and the choroid.
Methods: Case report.
Results: A 46 year-old man presented one day after a perforating ocular injury with an exit wound close to the inferior temporal retinal vascular arcade. The next day, the patient underwent a combined vitrectomy and phacoemulsification with intraocular lens implantation. During vitrectomy, a retinochoroidectomy was performed at the exit wound and the internal limiting membrane was peeled over the macula and up to the exit wound. Laser retinopexy was followed by plugging of a piece of the amniotic membrane to the exit wound. A second piece of the amniotic membrane was used to cover the bare retinochoroidectomy area. The surgery was concluded with a silicone exchange. Postoperatively, no sign of proliferative vitreoretinopathy was observed, and at 3 months the silicone oil was removed. The follow up was uneventful and the eye achieved a final visual acuity of 20/30.
Conclusion: The amniotic membrane may offer a simple and safe solution for the repair of the exit wounds of perforating injuries involving the retina and the choroid. The use of amniotic membrane for this purpose may afford the opportunity for early vitrectomy in the management of perforating ocular injuries.
