Do define() statements need phpDocumentor-style docblocks?

I would say the section Constants in the WordPress: PHP Documentation Standards is pretty clear. It should look like this:

/**
 * Summary.
 *
 * @since x.x.x (if available)
 * @var type $var Description.
 */
define( 'MY_CONST', 'Hello' );
