Posturing Time after Macular Hole Surgery Modified by Optical Coherence Tomography Images: A Pilot Study

PURPOSE: To see the early postoperative stage of macular hole (MH) surgery and to distinguish eyes needing prolonged posturing from those that do not use Fourier-domain optical coherence tomography (FD-OCT). DESIGN: Interventional case series. METHODS: Sixteen eyes of 15 patients with MH underwent the protocol at Kagoshima University Hospital. After the pars plana vitrectomy with 16% SF6 gas tamponade followed by posturing, the eyes were examined by FD OCT from 3 hours to the day after surgery. After MH closure was confirmed, posturing was stopped. Follow-up was per-formed for 4 months or longer. The main outcome measures included time and OCT finding of MH closure after surgery. RESULTS: On the day after surgery, the macula could be examined by FD-OCT in 13 of 16 eyes; 10 eyes had a closed MH and 3 had an unclosed MH. At day 2, 2 of the 3 eyes with unclosed MHs on day 1 demonstrated a closed MH. Posturing continued for 8 days in 4 eyes whose MH closure was not confirmed. The MH was closed in all eyes within 1 month. FD-OCT showed bridge formation of the neural retina in 9 eyes and simple closure in 3 eyes within 7 days. At 1 month, 12 eyes showed simple closure and 4 eyes showed bridge formation. Among 9 eyes with bridge formation within 7 days, 6 eyes had changed to simple closure at 1 month. CONCLUSIONS: FD-OCT enabled confirmation of MH closure the day after surgery even in gas-filled eyes. This imaging method may be a good indicator to determine when to stop posturing for each patient.
