Intraoperative optical coherence tomography (OCT) images are easy to obtain and clinically useful during all phases of vitrectomy and are of excellent quality. Par focality and coupled optical and OCT magnification allow for wide-field OCT during peripheral pars plana vitrectomy. OCT imaging can be obtained through vitreous, balanced salt solution, air, gas, and silicone oil. Live, continuous line scan and a variety of cube scan options are possible.
