Purpose: The purpose of this study was to study the incidence and factors influencing retinal displacement in eyes treated for rhegmatogenous retinal detachment (RRD) with pars plana vitrectomy (PPV) and gas or silicone oil.Methods: This was a prospective observational case series. One hundred twenty-five eyes with macula-off RRD from 125 patients underwent 25-gauge PPV at two vitreoretinal institutional practices. Eyes without proliferative vitreoretinopathy (PVR) or PVR grade A were tamponated with sulfur hexafluoride (SF6) gas, whereas eyes with PVR grade B received 1000 centistokes silicone oil (SO). The patients postured face-down immediately after surgery. Blue-fundus autofluorescence (B-FAF) pictures were obtained at each follow-up examination. Main outcome measures were incidence and direction of retinal displacement.Results: Ninety-seven eyes (77.6%) were tamponated with SF6 and 28 eyes (22.4%) with SO. After retinal reattachment, displacement was observed in 44 of 125 (35.2%) eyes (40 eyes in the SF6 group and 4 eyes in the SO group, respectively). The type of tamponade, specifically gas, was the only significant predictor of retinal displacement (P = 0.007). The displacement was downward in 39 (88.6%) eyes (36 tamponated with SF6 and 3 with SO) and upward in 5 (11.4%) eyes (4 tamponated with SF6 and 1 with SO).Conclusions: Displacement of the retina after repair of macula-off RRD with PPV is observed using either SF6 gas or SO. Downward and upward displacements may occur with both tamponades, but downward dislocation is more common. Of the factors potentially implicated in favoring displacement that were studied, only the type of tamponade, specifically the gas, was significant.

Abstract

One hundred twenty-five eyes with macula-off RRD from 125 patients underwent 25-gauge PPV at two vitreoretinal institutional practices. Eyes without proliferative vitreoretinopathy (PVR) or PVR grade A were tamponated with sulfur hexafluoride (SF6) gas, whereas eyes with PVR grade B received 1000 centistokes silicone oil (SO). The patients postured face-down immediately after surgery. Blue-fundus autofluorescence (B-FAF) pictures were obtained at each follow-up examination. Main outcome measures were incidence and direction of retinal displacement.Results: Ninety-seven eyes (77.6%) were tamponated with SF6 and 28 eyes (22.4%) with SO. After retinal reattachment, displacement was observed in 44 of 125 (35.2%) eyes (40 eyes in the SF6 group and 4 eyes in the SO group, respectively). The type of tamponade, specifically gas, was the only significant predictor of retinal displacement (P = 0.007).
