Macular Hole Surgery after Treatment with Ocriplasmin for Full Thickness Idiopathic Macular Holes with Vitreomacular Traction
Purpose: To report the efficacy of Ocriplasmin in the treatment of small-medium sized idiopathic full thickness Macular Holes with focal Vitreomacular traction in comparison with vitreous surgery.
Methods: Retrospective observational single-centre small case series (n=6) studythat included patients who underwent vitrectomy after unsuccessful treatment ofsmall-medium size full thickness Idiopathic macular holes with ocriplasmin.
Results: 6 eyes with full-thickness macular holes and VMT were included, whereby in 4 eyes an epiretinal membrane was present (66.7%). Resolution of VMT after intravitreal injection of ocriplasmin was shown in three out of six eyes (50%) and in all six eyes after vitrectomy (100%). Of all six eyes presenting macular holes with a mean size of 265 µm ± 109 µm at baseline visit, five eyes showed persistent macular holes at the second follow-up visit with a mean size of 335 µm ± 166 µm. After vitrectomy no macular hole could be detected at the f inal follow-up visit.
Conclusion: We present our clinical experience with intravitreous injection of Ocriplasmin to confirm the presumed therapeutic effect in patients suffering from Vitreomacular Traction (VMT) with small-medium sizedfull thickness Macular holes (MH). Small macular holes could frequently be closed with only Ocriplasmin and without surgery with a 17% closure rate. Enlargement in all holes that failed to close with Ocriplasmin was observed in all treated eyes which makes us believe that the VMT could have a Protective role. Ellipsoid zone disruptions were evident in 50% of treated eyes and more common in eyes with successful VMT release. Although data on Ocriplasmin from several studies remain controversial but so far the results are consistent with the results and recommendations of other clinical studies and the European Medicine Agency. We agree that replacing vitrectomy for MHs with one injection of Ocriplasmin would be a very attractive option but so far Pars plana vitrectomy remain the treatment of choice for most eyes with MHs. Further Work is recommended to reveal the Cause of the ellipsoid zone Changes, the mechanisms of tractional forces and to investigate the Long term side effects of Ocriplasmin.
