Figure 2. Variations in tear osmolarity.

Figure 2

In both the dry eye and normal groups, the differences between the minimum and the maximum tear osmolarities that were measured for each subject during the course of the 8-hour study period fell within a wide range of values. The solid line indicates the average of the maximum differences in the tear osmolarity values of the members of the dry eye group; the dashed line indicates the average of the maximum differences in the osmolarity values of the members of the normal group.
