Outcomes of Inverted Internal Limiting Membrane Flap Technique for Large Idiopathic Macular Holes Surgery in Patients at A Tertiary Care Hospital
Introduction: Large macular holes cause significant reduction in central visual acuity. The aim ofthe study is to find out short term anatomical and visual outcomes of inverted internal limitingmembrane flaps technique for large macular holes (base diameter>1000μm) surgery in patientsat a tertiary care hospital. Methods: A descriptive cross-sectional study was conducted in a tertiary care hospital fromJanuary 2018 to December 2018 after ethical clearance from the institutional review committee.The study was done in 12 patients with idiopathic macular holes (base diameter>1000μm), theywere repaired with 25 gauge pars plana vitrectomy with brilliant blue assisted large invertedinternal limiting membrane flap technique. Statistical analyses were performed using SPSS 19.0. Results: All twelve eyes had complete anatomical closure. Mean best corrected visualacuity preoperatively was 1.48 logMAR±0.246. The mean macular hole base diameter was1217.0±196.77μm. The mean age of patients was 68.75±4.97 years. Postoperatively,mean best corrected visual acuity was 0.978 logMAR±0.12. There were no postoperativecomplications. All the patients perceived decreased size of central scotoma. Conclusions: Inverted internal limiting membrane flaps for large macular holes is suitable methodfor closure of the very large hole, restoration of functional vision and decreased size of centralscotoma.
