Abstract

Vitreoretinal surgery is an extremely challenging surgical discipline requiring surgeons to use limited visualization to locate and safely operate on particularly delicate eye structures. Intraocular image guidance can potentially aid in localizing retinal targets, such as Epiretinal Membranes. This paper describes a system and methods for localizing difficult to identify anatomical features in the retina using video stereo-microscopy and intraocular OCT. We visually track the retina motion and relative position of a hand-held OCT probe to assemble an M-Scan, the cross-sectional image of the anatomy corresponding to a trajectory of the probe across the retina. The surgeon is then able to interrogate the OCT image during the procedure by pointing a surgical instrument at the M-Scan trajectory superimposed on the retina and displayed in 3D. The system is designed to provide relevant intraoperative imaging to increase surgical precision, and minimize the surgeon's cognitive load. We describe our system and quantify its performance in a phantom eye.
