Figure 2:

Pachymetry results showing corneal thickness in the left eye (A) before, (B) one week after and (C) four months after amantadine was discontinued. The colours correspond to the range of corneal thickness. Normal cornea thickness is about 550 μm (green to blue) with the thinnest area in the centre. The purple colour centrally in A and B indicates increased corneal thickness. The images show resolving corneal edema over time after amantadine was stopped. Image D shows the difference in corneal thickness between time points A and C.
