ABSTRACT
Purpose: We investigated factors affecting imaging of spectral-domain optical coherence tomography (SD-OCT) in gas-filled eyes after macular-hole (MH) surgery. Methods: The study comprised 25 eyes in 23 patients, eight men and 15 women, with a mean age of 66.9 (48-77) years, all of whom had undergone vitrectomy for MH. Sulfur hexafluoride (SF) gas was used as a tamponade, and the patients were maintained in a prone position after surgery. The SD-OCT imaging was performed on postoperative days 1 and 2. Results: The success rate of imaging was 88.0% (22/25 eyes) on postoperative day 1 and 95.8% (23/24 eyes) on postoperative day 2. The rate of MH closure in successful imaging cases was 81.8% (18 eyes) on postoperative day 1 and 95.7% (22 eyes) on postoperative day 2. The imaging accuracy in gas-filled eyes increased by setting the focus value of the OCT to a myopic refractive shift. Conclusion: The imaging of many gas-filled eyes following MH surgery is possible, even at the early postoperative stage, by setting the focus value of the OCT to a myopic refractive shift.
