Here are a couple of best practice suggestions for dealing with revisions:
It is also important to check how the author(s) have responded to the reviewer comments. Different journals prefer different methods; a letter from the authors responding to each of the reviewers comments, "track changes" (MS Word) or highlighted text, etc. Whatever method is used, it is important that the changes are clear to both editors and reviewers.
For revised submissions to double blind journals, check that the authors do not identify themselves in their response to reviewer comments.
