Abstract: Highlights•We identify a novel OCT-OCTA translation motivation, which is to maintain the consistency of OCTA image views.•We introduce a novel Heuristic Contextual Guidance (HCG) to enhance OCTA projection map quality.•We propose a novel Vessel Promoted Guidance (VPG) module to enhance vessel quality in OCTA projection maps.•We evaluate our TransPro on OCTA B-scan images and projection maps using common and proposed vessel-specific metrics.•Our TransPro surpasses SOTA methods on OCTA-3M and OCTA-6M datasets, demonstrating its quantative and qualitive effectiveness.
