i-Clarity has an extensive list of ethnicities linked to fast map mapping categories, and these can be edited in the Misc. 5 tab of Maintenance:

Select the fast map mapping category from the dropdown list next to the relevant ethnicity.

The ethnicity can be selected from a dropdown list in the clinical records and, if you have your OCT machine connected to i-Clarity, the fast map mapping category will automatically be used by the OCT to set normal values based on the ethnicity selected and the category associated with it in the Misc. 5 tab.
