Abstract:

Objective: To analyze the anatomical success rate and functional outcomes of patients with rhegmatogenous retinal detachment (RRD) who underwent 23-gauge pars plana vitrectomy plus 20% sulfur hexafluoride (SF6) gas endotamponade.

Methods: A retrospective, observational, cross sectional study. Fifty-one eyes of 50 consecutive patients underwent 23 gauge pars plana vitrectomy with sulfur hexafluoride gas tamponade were included. The anatomical success rate, visual outcome, and the type and frequency of complications were investigated.

Results: The 50 patients with a mean age of 50.16 (±10.3) years.  The rate of permanent single-intervention attachment was 94.1%. A second surgical intervention for the treatment of re-detachment became necessary in three eyes during follow-up. Finally, the retina was completely attached in 50 (98%) eyes. Mean log MAR visual acuity improved from 1.71 ± 0.68 (1/60 Snellen equivalent) preoperatively to 0.68 ± 0.4 (6/30 Snellen equivalent) postoperatively (P<.001). Significant differences in visual acuity were found in relation to the preoperative status of the fovea.

Conclusion: The surgical treatment of RRD using 23-gauge PPV with expansive gas tamponade renders excellent anatomical results and improvement in BCVA.
