Abstract
This study aims to establish an optimal scanning protocol for effective visualization of the choriocapillaris (CC) using a 1.6 MHz FDML OCT system. A step-bidirectional scanning method is employed along with a buffer averaging approach. We investigate three different interscan times (1-ms, 2-ms, & 3-ms) on repeated B-scans and find that shorter interscan times provide clear CC vasculature. Additionally, we examine CC imaging across three different repeated B-scan sets (4, 5 & 6), observing similar vascular patterns in all. We conclude that a combination of shorter interscan time with the four BM scan protocol and step-bidirectional scanning with buffer averaging is the optimum scanning protocol for effectively visualizing the CC.
