Abstract

We developed a novel combined SD-OCT + TD-FF-OCT device that provides cell-resolution view of TD-FF-OCT without compromising SD-OCT performance. SD-OCT gives global view for eye exploration and FF-OCT shows cell-detail in the central region of the OCT scan. Eye imaging is fast enough to be part of the routine clinical exam (10 min/patient). Four patients with different eye pathologies were imaged. FF-OCT resolved: striae (stromal mechanical folds), guttata, loss of endothelial cells and stromal cuts following the surgery. Additionally, we could access the trabecular meshwork region of the eye and obtain the first images of meshwork fibers at micron resolution.
