How can you use “annular” in a sentence? Here are some example sentences to help you improve your vocabulary:

The regions studied were the central 1000-micron diameter circular subfield and the 3000-micron outer diameter annular subfield (with 1000-micron inner diameter) centered on the fovea (the 1500 micron diameter anatomical center of the macula).
We therefore constructed appropriate annular zones in the macula for percentage (multiplicative) increases in brightness to be empirically determined using published data on the spatial distribution of macular pigment [ 29 30 ] . These observers found that the macular pigment density (hence optical density) is greatest centrally, drops to half-maximum within a diameter of 500 to 600 μm, reaches a quarter-maximum at a diameter of about 1000 μm, and thence tapers slowly to a low constant level within a 2000 μm diameter region.
