The Trilepis-type can be derived from the Carex-type by a flattening of the scutellum and a shifting of the root cap to a
subbasal position (Fig.
in eyes examined in the prodromal period before the onset of clinical EKC, the epithelial, Bowman's, and stromal layers appeared normal in iVCM, while the
subbasal plexus showed an increased number of Langerhans cells (Figure 1).
Their work reveals that, in general, most microcreagrines have ist

Figure 1 shows the larger stromal nerve and the very thin nerves of the
subbasal nerve plexus.
Previous ophthalmologic studies demonstrated a complex relationship between the
subbasal nerve plexus (SNP), decreased corneal sensation, and the development of diabetic retinopathy and neuropathy [13].
However, to our knowledge, there are no reports of a case so closely observed: we observed the process in which the blocked corneal nerve was restored within several months after disappearance of
subbasal nerve fibers due to the trigeminal nerve block as well as the accompanying improvement of corneal findings.
At the junction of the lesion and transparent cornea, however, a large number of dendritic cells, basal epithelial cells, and
subbasal nerve plexuses were observed to form netting via long interdigitating dendrites.
Moreover, the occupied area of the corneal
subbasal nerve in the diabetic + SA group showed a significant increase compared with the diabetic group ( F = 11.918, P = 0.024), which was still less than that of the control group [ F = 8.000, P = 0.047; [Figure 2].{Figure 2}

Subsequently, human corneal
subbasal nerve plexus demonstrated by IVCM is dealt with in the latest reports.
In subchorial and
subbasal departments there were old and fresh bleeding, blood clots, excessive fibrinoid depositions, and small calcifications.
