Abstract Details



Purpose:

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).

Setting:

Retina Eye Hospital Bursa-TURKEY

Methods:

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.

Results:

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.

Conclusions:

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.
