Example of manually annotated borders of the individual retinal layers on an optical coherence tomography scan. (a) Border between vitreous and NFL, (b) border between NFL and GCL, (c) border between IPL and INL, (d) border between INL and OPL, (e) border between OPL and ONL, (f) border between ONL and ELM, and (g) all annotated borders. Annotations were performed on each scan with different averaging settings; thus, on 7 scans preoperatively and 7 scans postoperatively for each patient.
