Fig. 4.2 Survey of development occurring in the same corneal area between 5 weeks and 15 months after symptom onset. This series visualizes light-reflecting changes, a property shared by the rounded/abnormal cells and changes in the superficial stroma. As in Fig. 4.1, exact locations cannot be pin-pointed but the shape of the figure is recognizable up to 15 months

Fig. 4.4 (a) In the area indicated by frame in Fig. 4.3a are visible many rounded/abnormal cells, individual (arrowhead) and grouped, some located within darker spots (arrow). (b) A different area showing many rounded/abnormal cells (arrowhead)

Fig. 4.5 (a–c) Survey, 4 weeks after symptom onset. With fluorescein (c) it is visible that the rounded/abnormal cells, both individual (arrowheads) or grouped (arrows), are located below intact surface layer/s. The area in frame in (a) is shown at higher magnification in Fig. 4.6a and in (c) in Fig. 4.6b (below). (The markers are placed in corresponding locations)

Fig. 4.6 (a) Many rounded/abnormal cells (arrowhead) within the area indicated by frame in Fig. 4.5a; some are located within darker spots (arrow). (b) In the area indicated by frame in Fig. 4.5c are visible heaped-up rounded/abnormal cells (arrowhead) in areas of surface elevation (dark in the green stained tear film, bowed arrow) and a few green dots (straight arrow)
