PURPOSE:to compare functional and anatomical results in two groups of patients with epiretinal membrane (ERM) who underwent 23 gauge pars plana vitrectomy (PPV 23G), ERM and internal limiting membrane (ILM) peeling and tamponade with balance saline solution (BSS) or sulfur hexafluoride 20% (SF6 20%).
Eye Clinic, University of Verona
16 eyes of 16 patients with ERM and without other ocular disease were randomized into two groups. All the eyes underwent PPV 23 G, ERM and ILM peeling performed by one surgeon. The first group (10 eyes) was tamponade at the end of surgery with BSS and the second group (6 eyes) was tamponade with SF6 20%. Preoperatively, 1 and 2 months after surgery all the patients underwent a complete eye examination including evaluation of best corrected distance visual acuity (BCDVA), best corrected near visual acuity (BCNVA), assessment of metamorphopsia (Amsler test) and central macular thickness (CMT) measurement with spectral domain optical coherence tomography (SD-OCT).
We found a statistically significant difference between the BCDVA and the BCNVA after surgical removal of ERM and ILM, increasing from the first to the second month even if the final CMT was not significantly dependent by the choice of the tamponade. The recovery of both the BCDVA and the BCNVA was faster in the second group of patients than in the first group. However the analysis failed to show any significant difference between the two groups regarding the BCDVA, the BCNVA or the reduction of the CMT.
the improvement of the visual acuity and the reduction of the CMT were faster in SF6 20% tamponade group than in BSS tamponade group. Anyway 2 months after surgery the results are equivalent.
