Abstract
The aim of this consecutive, retrospective, nonrandomized study is to assess the safety and success of short-term heavy silicone oil removal after pars plana vitrectomy for complex retinal detachment. To date, the lengthening of the timing of silicone oil can lead to less visual gains and more complications is known.Purpose:To assess the success of the short-term location of the heavy silicone oil (Densiron 68, HSO) as endotamponade after pars plana vitrectomy for rhegmatogenous complex retinal redetachment.Methods:Consecutive, retrospective, nonrandomized, pilot study was conducted. Twenty-two eyes of 22 patients with complex inferior retinal redetachment previously tamponade with gas (SF6 or C3F8) or 1000 cSt standard silicone oil (SSO) were selected. All were treated with HSO endotamponade, and its removal was performed after 1 month. The main outcomes were best-corrected visual acuity and postoperative complications after the HSO removal.Results:Of the 22 eyes, 10 were treated with SSO endotamponade, 3 with fluorinated gas 14% C3F8, and 9 with 20% SF6 at first surgery. In all eyes, a complex inferior retinal redetachment was observed after the first surgery, in 1 month to 3 months after silicone oil removal or gas endotamponade introduction. In 10 eyes, the proliferative vitreoretinopathy (Grade B or C 1-3) was found. The main best-corrected visual acuity before HSO removal was 0.55 +/- 0.20 the logarithm of the minimum angle of resolution (range 0.4-0.7) and after the HSO removal, it was 0.32 +/- 0.29 the logarithm of the minimum angle of resolution (0.1-0.4). Among the postoperative complications, only in four eyes the macular edema was found (medically resolved), in four eyes an increase of intraocular pressure, and none of these developed the epiretinal membrane.Conclusion:The main purpose of this study is to establish a short-term HSO endotamponade in eyes with complex retinal detachment recurrences, reducing the possible postoperative complications and having a better prognosis for visual acuity outcomes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
