Figure 4. The palisades of Vogt were absent in all quadrants of all patients. The transition of superficial epithelial morphology in all cases (100%) was abrupt with an immediate transition from a conjunctival-shaped epithelium to a corneal-shaped epithelium in five of the six patients (Figures 1E–5E) and to a discontinuous and irregular central epithelium in the last patient (Figure 6E).
