While previous studies have explored various scanning protocols to enhance CC visualization, most approaches rely on oversampling, beam size adjustments, large numbers of repetitive B-scans (BM), and volume registration. However, interscan time\u2014a critical parameter that influences flow contrast and vascular detail\u2014has been largely overlooked. In this Letter, we introduce interscan time as a novel, to the best of our knowledge, CC imaging parameter and propose an optimized OCTA protocol by leveraging a 1.6 MHz FDML swept-source laser and step-bidirectional scanning method to investigate its impact across beam sizes and BM-scans. Our findings reveal that shorter interscan time significantly improves CC visualization by enhancing vessel contrast and preserving microvascular details, enabling better clinical assessment of retinal diseases such as age-related macular degeneration and diabetic retinopathy.\n                  <\/jats:p>","DOI":"10.1364\/ol.557992","type":"journal-article","created":{"date-parts":[[2025,3,17]],"date-time":"2025-03-17T10:00:34Z","timestamp":1742205634000},"page":"2711","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effective interscan time for enhanced\n                    <i>in vivo<\/i>\n                    choriocapillaris imaging with OCT angiography"],"prefix":"10.1364","volume":"50","author":[{"given":"Mohammad","family":"Shahidul Islam","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03rmrcq20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Song","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03rmrcq20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ansel","family":"Chen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03rmrcq20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zaid","family":"Mammo","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03rmrcq20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4907-3732","authenticated-orcid":true,"given":"Myeong","family":"Jin Ju","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03rmrcq20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2025,4,14]]},"reference":[{"key":"ol-50-8-2711-R1","doi-asserted-by":"publisher","first-page":"100997","DOI":"10.1016\/j.preteyeres.2021.100997","volume":"87","author":"Lejoyeux","year":"2022","journal-title":"Prog.
