A choroidal slab of 200° OCTA image (montage from four 120° captures). By TowardPi 400KHz speed SS-OCTA system with proprietary choroidal vessel algorithm (3D dataset without retinal shadow, not a simple reversal of enface).

The number of vortex veins is known to vary from 4 to 8 in human eye, with 4 or 5 in most normal population. 8 vortex veins got visualized in this scan. Have you found them all?

“I’m amazed that TowardPi OCT can obtain high-definition and ultra-wide blood flow images so fast. It provides a convenient and accurate examination method for clinical work. We look forward to TowardPi's persistent efforts to launch more top-class products for the benefit of ophthalmologists in the world!” Image courtesy and endorsement: Prof. XueDong Zhang, The First Affiliated Hospital of ChongQing Medical University, China
