Recurrent macular edema in BRVO

This 60 yo man in his mid 60’s came to see me recently. He has a history of TYpe 2 DM and hypertension both well controlled. He had received intravitreal anti VEGF injections for BRVO related macular edema in the right eye years ago ( unclear of the number) 

Now RVA 6/18 ( previously 6/7.5) but OCT shows no appearance of fluid?
