          Abstract

          A young patient who showed rhegmatogenous retinal detachment with preoperatively undetected retinal break was successfully treated by scleral buckling using a noncontact wide-angle viewing system.

            Comparison of scleral buckling with combined scleral buckling and pars plana vitrectomy in the management of rhegmatogenous retinal detachment with unseen retinal breaks.

            The purpose of the present paper was to compare the techniques of conventional scleral buckling and combined pars plana vitrectomy and scleral buckling procedures in rhegmatogenous retinal detachments with unseen retinal breaks. Forty-four consecutive eyes with uncomplicated, primary rhegmatogenous retinal detachments with a clear media and unseen retinal breaks were randomized to two groups. The scleral buckling group underwent 360 degrees scleral buckling, cryopexy and external subretinal fluid drainage. In the combined surgery group, 360 degrees scleral buckling, pars plana vitrectomy, air-fluid exchange, endolaser and injection of 14% perfluoropropane gas was done. At 3 months follow up the primary reattachment rate was 80% (16/20 cases) in the combined surgery group, and 70% (14/20 cases) in the scleral buckling group (P = 0.716). The visual acuity improved significantly from a preoperative median of hand movement (HM; range: HM to 6/60; similar in both the groups), to a median of 6/60 (range: perception of light to 6/18) in the combined surgery group and a median of 6/36 (range: HM to 6/18) in the scleral buckling group, the difference between the two groups not being statistically significant (P = 0.4). The number of intraoperative and postoperative complications was more in the combined surgery group. (four cases were lost to follow up and were doing well when last examined.) Conventional scleral buckling was found to be a safe and effective technique in the primary management of uncomplicated, rhegmatogenous retinal detachments with unseen retinal breaks when the media is clear.

              Identification of retinal breaks using subretinal trypan blue injection.

              To describe the use of subretinal trypan blue to identify retinal breaks during vitrectomy for rhegmatogenous retinal detachment (RD). Interventional case series. Five patients with RD in whom no retinal break could be identified by internal search with scleral indentation. Trypan blue 0.15% was injected transretinally into the subretinal space using a 41-gauge cannula designed for macular translocation surgery. Perfluorocarbon heavy liquid was then injected into the vitreous cavity and the eye was rotated such that trypan blue was vented out of the break. The plume of trypan blue was used to identify retinal breaks, or in some cases staining of the break facilitated break detection. Subretinal fluid was then drained through the break or a drainage retinotomy and surgery was completed using standard techniques. Identification of previously unseen retinal breaks. This technique successfully identified a retinal break in 4 out of 5 patients. After absorption of the gas tamponade all retinas remained attached with a median visual acuity of 6/12. Failure to identify a retinal break during RD surgery is a well-recognized clinical challenge that may adversely affect outcome. In this setting, chromophore-assisted retinal break detection may be a useful surgical technique.
