Bandello 2004
Reason for exclusion Comparison intervention did not meet inclusion criteria: Intravitreal injection was compared to intravitreal injection plus grid-laser photocoagulation treatment.
Bonini-Filho 2005
Reason for exclusion Comparison intervention did not meet inclusion criteria: Intravitreal injection was compared with sub-Tenon's infusion of tramcinolone acetonide. The same drug was used but with different means of administration.
