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.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
