Purpose -To evaluate the efficacy and optimum timing for resurgery in case of persistent macular hole(MH).
Methods –18 eyes of 18 patients who underwent fluid air exchange with intravitreal C3F8 for persistent MH after vitrectomy+Internal limiting membrane peeling+SF6 were included in the study. Best corrected visual acuity (BCVA),optical coherence tomography( OCT) features including base diameter and configuration of MH,time duration between two surgeries were noted.
Results–Patients who underwent resurgery within 3 months of first surgery had better anatomical closure rate compared to those who underwent resurgery after 3 months(p=0.04).Significant improvement was seen in BCVA in eyes with closed MH and better anatomical closure for MH with irregular edges on OCT was noted.
Conclusion-Patients undergoing repeat gas injection within 3 months of primary surgery for persistent macular hole have better anatomical closure rates compared to late intervention(>3 months).
