Abstract
PURPOSE: To compare the anatomical and functional outcomes of macular hole (MH)-associated retinal detachment after vitrectomy with the internal limiting membrane (ILM) insertion technique or the inverted ILM flap technique. METHODS: In this retrospective observational study, we reviewed the medical records of 49 eyes with MH-associated retinal detachment that underwent vitrectomy with the ILM insertion (26 eyes) or ILM flap (23 eyes) technique. RESULTS: The MH closure rate at 12 months was greater in the ILM flap group versus the ILM insertion group (95% vs. 73%, respectively, P = 0.059). The postoperative best-corrected visual acuity (BCVA) at 12 months was significantly better in the ILM flap group (P = 0.014). All eyes (100%) showed an improvement in the BCVA of ≥0.3 logarithm of the minimum angle of resolution (15 Early Treatment Diabetic Retinopathy Study letters) in the ILM flap group versus 20 eyes (77%) in the ILM insertion group (P = 0.026). The preoperative BCVA and the ILM flap technique were significantly correlated with the postoperative BCVA (P = 0.028 and 0.027, respectively) and BCVA improvement (≥0.3 logarithm of the minimum angle of resolution [15 Early Treatment Diabetic Retinopathy Study letters]; P = 0.003 and 0.026, respectively). CONCLUSION: The inverted ILM flap technique was more effective in improving the postoperative BCVA in patients with MH-associated retinal detachment when compared with the ILM insertion technique. The preoperative BCVA and the ILM flap technique were independent prognostic factors for visual outcomes in patients with MH-associated retinal detachment.
