PP265 : Efficacy of modified Inverted ILM Flap Technique for the Treatment of chronic and large Macular Hole

Dr.PRITAM MADHUKAR BAWANKAR

PURPOSE:To evaluate efficacy of modified Inverted Internal Limiting Membrane Flap Technique for the Treatment of chronic(> 12 month) and large(>700 microns) Idiopathic Macular Hole. METHODS:11 eyes of 11 patients underwent surgery. In this technique after folding ILM flap inside the macular hole, approximately 0.2 mL of viscoelastic is injected over the ILM flap, forming a “viscoelastic cap”, that help in retention of flap inside macular hole during fluid gas exchange. The main outcome measure was preoperative and postoperative( at 1week, 1,3,6 and 12 month) visual acuity and macular hole closure rate. RESULTS:Mean visual acuity improved from 1.2 logMAR to 0.56 logMAR. We confirmed the closure of the macular hole with spectral domain optical coherence tomography in all cases. CONCLUSION: Procedure suitable for redo cases where there is no ILM bordering the macular hole and improve the reliability and reproducibility of the operation.
