The comparison of the surgical outcome of 27-gauge pars plana vitrectomy for primary rhegmatogenous retinal detachment between air and SF6 gas tamponade

Learning objectives Upon completion of this activity, participants will be able to: Compare anatomical success rate between air and 20% SF6 tamponade in 27GPPV for RRD, according to a retrospective, observational, and consecutive study. Compare visual outcomes and changes in intraocular pressure during 12-month follow-up between air and 20% SF6 tamponade in 27GPPV for RRD, according to a retrospective, observational, and consecutive study. Compare type and frequency of complications during 12-month follow-up between air and 20% SF6 tamponade in 27GPPV for RRD, according to a retrospective, observational, consecutive study, and describe other clinical implications regarding surgical outcomes.

Objectives To compare the surgical results between air and 20% sulfur hexafluoride (SF6) tamponade in 27-gauge pars plana vitrectomy (27GPPV) for rhegmatogenous retinal detachment (RRD). Methods A retrospective, observational, and consecutive study. All patients underwent 27GPPV for RRD were divided into two groups. Group A comprised patients who underwent 20% SF6 gas tamponade. Group B comprised patients who underwent air tamponade. The anatomical success rate, visual outcome, and the type and frequency of complications were investigated and compared between the groups. All patients were followed-up for 12 months after surgery. Results Seventy eyes were enrolled (Group A: 35 eyes, Group B: 35 eyes). Seventeen eyes in Group A and 13 eyes in Group B had RRD with superior retinal breaks, while 14 eyes in Group A and 19 eyes in Group B had RRD with inferior retinal breaks. There was no statistically difference in preoperative demographic date between the groups. The initial and final anatomical success rates were 97.1% and 100% in Group A and 94.3% and 100% in Group B, respectively. The success rates between the groups were not statistically different (p = 1). The best corrected visual acuity (BCVA) (logMAR) at 12 months after surgery was -0.02 +/- 0.14 in Group A and -0.03 +/- 0.27 in Group B. The BCVA between the groups was not statistically different (p = 0.27). Conclusions The surgical results of air tamponade were not inferior to 20% SF6 tamponade in 27GPPV for RRD irrespective of retinal break locations in the present cohort.
