Abstract.Near-exact retro Banach frames has been discussed with the help of examples. A Krein-Milman-Rutman type stability result for retro Banach frames has been obtained. Finally, it has been proved that a block sequence with respect to a retro Banach frame can be extended to a retro Banach frame.
