Claim 14:
15. A system for imaging a target site, the system comprising:
a housing assembly having a head unit configured to be at least partially directed towards the target site;
an optical coherence tomography (OCT) module at least partially located in the head unit and configured to obtain a first set of volumetric data of the target site;
a stereoscopic visualization camera at least partially located in the head unit and configured to obtain a second set of volumetric data of the target site, the second set of volumetric data including first and second views of the target site;
a controller in communication with the stereoscopic visualization camera and the OCT module;
a volumetric render module selectively executable by the controller;
wherein the controller has a processor and tangible, non-transitory memory on which instructions are recorded, execution of the instructions causing the controller to:
register the first set of volumetric data from the OCT module with the second set of volumetric data from the stereoscopic visualization camera to create a third set of registered volumetric data;
render the third set of registered volumetric data to a first region to obtain a two-dimensional OCT view, via the volumetric render module;
render the second set of volumetric data from the stereoscopic visualization camera to a second region to obtain a live two-dimensional stereoscopic view, via the volumetric render module; and
overlay the first region and the second region to obtain a composite shared view of the target site;

wherein registering the first set of volumetric data with the second set of volumetric data includes aligning a local area of interest in the first set of volumetric data in position, orientation and size with the second set of volumetric data; and
wherein the local area of interest includes at least one of a corneal limbus and a scleral vasculature.
