ABSTRACT

Abstract?AlM To evaluate the efficacy of intravitreal injection with Ranibizumab combined with sub-Tenon injection with Triamcinolone acetonide ( TA ) for macular edema ( ME) due to central retinal venous occlusions ( CRVO) .?METHODS:Forty-six patients (46 eyes) were diagnosed ischemic CRVO with significant macular edema by fundus fluorescence-angiography ( FFA ) and optical coherence tomography ( OCT ) . All the patients had panretinal photocoagulation ( PRP ) , a week after the four times therapies. Twenty-three patients ( 23 eyes ) in group A were randomly chosen to receive intravitreal injection with ranibizumab ( lVR ) , another 23 patients ( 23 eyes ) in group B to treat with both lVR and sub-Tenon injection with TA ( PSTT ) . There was no significant difference on macular edema and best corrected visual activity ( BCVA) between the two groups. The changes in BCVA and central macular thickness ( CMT) before and 1wk; 1, 3, 6mo after treatments were analyzed.?RESULTS: One week after the treatment the BCVA increased while the CMT decreased compared with that of pretreatment in groups A and B (P0. 05).?CONCLUSlONNot only lVR can decrease ME caused by CRVO and increase the BCVA, but also lVR combined with PSTT can. But combined therapies can be more rapidly and have more positive effect on decreasing the ME and protecting the visual function.
