Abstract
Purpose
To report outcomes of re-vitrectomy using light silicone oil (SO) tamponade for persistent macular holes (MHs).
Methods
We reviewed cases of patients with full-thickness MHs that underwent pars plana vitrectomy (PPV) with air/gas and were re-vitrectomized using light SO tamponade after primary non-closure (persistent MHs). Outcome measures included anatomic closure rates and patterns confirmed by optical coherence tomography (OCT) and changes in best-corrected visual acuity (BCVA).
Results
A total of 42 eyes of 41 patients with unsuccessful primary PPV with air/gas were included. After re-vitrectomy with light SO (1000-centistoke), 29 (69%) eyes demonstrated type 1 closure without neurosensory defects in OCT scans, whereas 9 eyes (21%) showed type 2 closure with persisting neurosensory defects. Available data (n = 21) showed a significant mean improvement of BCVA from 0.99 logMAR (SD 0.25, range 0.7–1.3) preoperatively to 0.74 logMAR (SD 0.42, range 0.2–1.5) postoperatively (p = 0.035).
Conclusion
The treatment of persistent MHs with PPV and light SO tamponade resulted in high closure rates.
