Standard Dosing Group
Frequent dosing group
Standard Dosing Group will receive intravitreal injections of 0.3mg. ranibizumab at baseline, week 4 and 8 )sham injections at week 2 and 6). After week 8 retreatment will be given monthly if edema is greater than 290um or ETDRS visual acuity score <83
Frequent dosing subjects will be evaluated and treated every two weeks through week 8 with intravitreal injection of 0.3mg ranibizumab. Subjects will then be evaluated monthly through week 24 and will receive treatment with ranibiumab based on residual edema and visual acuity
