PURPOSE: To evaluate the efficacy and safety of combined 25-gauge (G) pars plana vitrectomy (PPV) with intravitreal dexamethasone implant (DXI) for the treatment of advanced stage epiretinal membrane (ERM). METHODS: Forty consecutive pseudophakic eyes with idiopathic stage 3-4 ERM and intraretinal cysts were randomly assigned to two treatment groups. Twenty eyes underwent combined 25-G PPV, ERM peeling and slow-release DXI (DEX group), whereas 20 eyes underwent standard 25-G PPV with ERM peeling only (control group). Differences in postoperative best-corrected visual acuity (BCVA), intraocular pressure (IOP), central macular thickness (CMT) were evaluated. RESULTS: In all patients, BCVA significantly increased at 1, 3 and 6 months after surgery compared to baseline (all p < 0.05), but at 3 and 6 months, the visual gain was higher in the DEX group (respectively, p = 0.036, p = 0.006). CMT was significantly lower in DEX group compared to control group at 3 and 6 months after surgery (respectively, p = 0.042, p = 0.003). There was no statistically significant difference in IOP change over the course of the follow-up between groups (p > 0.05). CONCLUSION: Combined 25-G PPV with DXI is associated with better anatomical and functional outcomes in patients with advanced stage ERM.

Abstract

PURPOSE: To evaluate the efficacy and safety of combined 25-gauge (G) pars plana vitrectomy (PPV) with intravitreal dexamethasone implant (DXI) for the treatment of advanced stage epiretinal membrane (ERM). METHODS: Forty consecutive pseudophakic eyes with idiopathic stage 3-4 ERM and intraretinal cysts were randomly assigned to two treatment groups. Twenty eyes underwent combined 25-G PPV, ERM peeling and slow-release DXI (DEX group), whereas 20 eyes underwent standard 25-G PPV with ERM peeling only (control group). Differences in postoperative best-corrected visual acuity (BCVA), intraocular pressure (IOP), central macular thickness (CMT) were evaluated. RESULTS: In all patients, BCVA significantly increased at 1, 3 and 6 months after surgery compared to baseline (all p < 0.05), but at 3 and 6 months, the visual gain was higher in the DEX group (respectively, p = 0.036, p = 0.006). CMT was significantly lower in DEX group compared to control group at 3 and 6 months after surgery (respectively, p = 0.042, p = 0.003). There was no statistically significant difference in IOP change over the course of the follow-up between groups (p > 0.05). CONCLUSION: Combined 25-G PPV with DXI is associated with better anatomical and functional outcomes in patients with advanced stage ERM.
