A single-suture technique for placement of the ganciclovir implant.

The ganciclovir implant is a surgically implanted sustained-release drug delivery system used for the treatment of cytomegalovirus retinitis. The device is suspended in the vitreous cavity through a pars plana incision. Previous reports of the surgical procedure have described securing the implant on 1 suture, tied with an external knot. The ends of this suture were left long to avoid sharp ends eroding through the conjunctiva. The wound was then closed with 1 or more additional sutures, with the ends tied and cut short. We describe a technique whereby the wound is closed and the implant secured with a single running suture. The advantages of this technique include efficiency and elimination of exposed knots. We have observed no complications attributable to this technique.
