Retro-Mode Scanning Laser Ophthalmoscopy Planning for Navigated Macular Laser Photocoagulation in Macular Edema

Figure 1

Artifacts in OCT retinal thickness maps that impede OCT-guided planning for navigated MLP. (a) Incorrect automated segmentation (in B scans, a green dashed line represents automated segmentation boundaries; white arrows on the map indicate the locations of B scans) resulting in the occurrence of zones with underestimated retinal thickness (indicated by map colors colder than red and limited by a yellow dashed line). (b) Off-center artifact due to fixation error (green mark represents the true foveal center identified with B scans; red mark represents the foveal center identified automatically; black lines on the map represent the locations of B scans).
