BTW, the fovea is a depression in the center of your macula. It is responsible for your highest visual acuity.
If you've ever seen an image of your OCT then this would make more sense....
Basically, in the eye on an OCT scan the fovea can be seen as a little dip or curve in the scan. If the fovea is blunted it means that that dip/curve is not as apparent, thus more raised.
Next, time you go to the drs. ask him/her to point this out on your OCT it helps to have a visual.
