At oxforddictionaries.com, they don't use a comma after 'e.g.' and 'i.e.'.

Period is required after 'i.e.' here in BrE.

But we would use a comma after 'for example' and 'that is' in a sentence.

So why is the comma omitted after each abbreviation? This, logically, does not make sense.

    That doesn't make the punctuation correct, however. They are being remiss, then, in showing proper punctuation usage. It certainly cannot be to save space.

    Because it's not in a sentence, that's why. Though using or not using a comma is a style issue, not a dictionary entry issue.

The Oxford Manual of Style (section 5.3) states:

To avoid double punctuation, no comma follows i.e. and e.g. in OUP style.

    Have they updated this? The Chicago Manual of Style went back and forth on the issue and is currently with the comma.

    The OUP tend to go their own way, and I don't have the latest edition.
