To investigate efficacy and safety of minimal (partial) vitrectomy to treat epiretinal membranes and vitreomacular traction syndrome.
Retrospective analysis of 176 cases of small gauge (23G=4 and 25G=174) 3-port-pars plana vitrectomy performed from January 2006 to May 2008 at Department of Ophthalmology of Bari (Italy) for epiretinal membrane (170 eyes) and vitreomacular traction syndrome (6 eyes). In cases of coexisting cataract, a phacoemulsification with IOL implant was performed immediately before vitreous surgery. Posterior vitreous detachment was achieved with cutter aspiration. Minimal PPV was carried out till the equator, without reaching the vitreous base. Vitreous traction and epiretinal membranes were removed. ILM was stained with ICG, and peeled with forceps. A partial fluid-air exchange was carried out before removal of cannulas. Best-corrected Visual Acuity, OCT, retinal biomicroscopy were examined at baseline, 1, 6 and 12 months post-operatively. At the last follow up, ultrasounds was used to confirm the persistence of residual peripheral vitreous.
After a mean follow-up of 15 months, mean BCVA was stable or improved in 167 eyes. Ninety-nine eyes improved more than 3 lines. All vitreomacular tractions and epiretinal membranes resolved and retinal tomograph profile was restored in all eyes after surgery, as confirmed by OCT. In all eyes ultrasounds showed persistent vitreous. Only 2 eyes developed retinal detachment after two weeks, requiring a complete vitrectomy with gas tamponade. No further complications were observed.
Minimal core-vitrectomy is an effective and safe procedure to treat epiretinal membranes and vitreomacular traction syndrome.
