Central and paracentral steepening of the cornea was observed in corneal topography (Figure 1).
Stromal keratocyte nuclei (arrow) and nerve fibers observed in Bowman's plane of the right eye in stage 3 keratoconus. Magnification 500x with 40x objective lens.

A thick, dense, bright artifact was observed in anterior stroma, which looked like a cluster of cells (Figure 4).
Thin dark bands (arrow) were observed in anterior stroma of the right eye in stage 3 keratoconus. Magnification 500x with 40x objective lens.

Thin, short, and discontinuous dark bands (striae) were observed in anterior stroma (Figure 5).
Thick dark bands (arrow) were observed in posterior stroma of the left eye in stage 2 keratoconus. Magnification 500x with 40x objective lens.
