To compare the anatomic and visual results and complications of perfluoropropane(C3F8) versus silicon oil tamponade after pars plana vitrectomy(PPV) in cases with complicated rhegmatogenous retinal detachment(RRD) with proliferative vitreoretinopathy(PVR).
Retina Eye Hospital Bursa-TURKEY
Interventional case series of consecutive patients undergoing pars plana vitrectomy for primary or recurrent complex RRD with grade C or D PVR were retrospectively classified into 2 groups according to type of internal tamponade (Group 1: C3F8 12% and Group 2: 1000cs silicone oil). Ocular trauma cases were excluded from the study. Anatomic and visual success after the primary surgery, mean operation numbers and complications were compared between two groups.
Twenty-five eyes in group 1 and 28 eyes in-group 2 were included in the study. Mean preoperative duration and postoperative follow-up in Group 1 were 67.8±57.8 (2-180) days and 10.12±8.54 (4-42) months, respectively. Single operation success (SOS) was obtained in twenty eyes (80%), while final anatomic success was obtained in 23 eyes (92%). Mean operation number per case in this group was 1.2. Mean best corrected visual acuity (BCVA) at preoperatively and final visit was 2,17±1,05 (3-0 logMAR) and 0,82±0,93 (3-0 logMAR), respectively (p<0,05). Mean preoperative duration and postoperative follow-up in Group 2 were 144.67±335.23 (3-1825) days and 18.68±20.08 (4-80) months, respectively. While, SOS was obtained in 24 eyes (85.7%), final anatomic success did not change. Silicone-out surgery was not yet performed in 8 eyes with anatomic success at final visit. Mean operation number per case in this group was 1.68. Mean BCVA at preoperatively and final visit was 2.83±0.5 (3-1.3 logMAR) and 1.33±1.1 (3-0 logMAR), respectively (p<0,05). There was no statistically significant difference in final anatomic and visual success between groups, although reoperation rate and complications were significantly higher in the silicone oil group.
While long-acting gas tamponade was comparable to silicon oil in terms of anatomical and visual success in cases with primary and recurrent RRD complicated by grade C and D PVR, it provided significantly lesser mean operation number and postoperative complications.
