Well, the following issues have Dick neck-deep in denial and unable to tell anyone one word about either Blockbuster or Tarantula and Bruce being completely blind - it was around War Games, so the period was pretty bad for everyone, and the next arc is Dick in the Mafia and away from everyone else. After that it's off to OYL and the less said about that the better.
So no, it wasn't dealt with that I know of, except for Devin Grayson being honest enough to keep Dick depressed and struggling. ...And Winick's stuff over in Outsiders, whose Dick was certainly grimngritty enough.
