Adaptive compensation for lamina cribrosa (LC) imaging. Baseline optical coherence tomography (OCT) images of two healthy patients and their enhanced versions using adaptive compensation to correct the effects of light attenuation. In the baseline images, arrows indicate poor visibility of the LC (red) and of the peripapillary sclera (blue). Adaptive compensation, when applied as a postprocessing treatment, allows recovery of the LC and peripapillary sclera even in cases where OCT signal is barely visible in the original images (left). Note that for the left image, the entire LC cannot be recovered. Adapted with permission from Mari et al.⁴²
