Corneal Nerve Regeneration after Self-Retained Cryopreserved Amniotic Membrane in Dry Eye Disease

Figure 4

Changes in corneal nerve density (a), dendritiform cell density (b), and corneal sensitivity (c), in the study group (solid lines) and control group (dash lines). In the study group, there was a significant increase in the central corneal nerve density and a nonsignificant change in the dendritiform cell density. In the control group, both corneal nerve and dendritiform cell density remained relatively unchanged.
