Comparison Effect of Interavitrealbevacizumab (Avastin) in Visual Acuity of Ischemic and Non Ischemic Diabetic Macular Edema Farzaneh Ghasemzadeh, 1 Reza Jafari 2 Received: 20/Dec/2011 Accepted: 30/Dec/2011 Background:To evaluate effect of ischemia in visual outcome after intravitrel injection of Avastin (Bevacizumab) for diabetic macular edema prospective interventional ( clinlical trial) study tertiary eye centre, Alzahra, zahedan, Iran. Materials and Method: patient with clinically significant Macular edema (CSME) undergone fluorsceine angiography (FA) Patient with fovea avascular zone(faz) larger than 100micrometer were defined to have ischemic macular edema.patientdevided in 2 groupes: ischemic and non Ischemic. Best corrected visual acuity (BCVA) and central macular thickness (CMT) measured in all eyes with optical coherence tomography (OCT) at baseline. then 3 times Injection of Avastin (Bevacizumab) intravitreally was done monthly. 1 month after third injection BCVA and CMT measured again: then data Compared before and after injection in 2 groupes. Results: 87 eye (66 patie nts ), 23 eye (26.4%) ischemic and 64 eyes (73.6%) nonischemic group. BCVA in nonischemic group improves from base line 0.653 0.309 Log MAR to 0.404 0.255(pvalue< 0.001) and BCVA in ischemic group had no significant changes 0.881 0.332 to 0.879 0.378 (pvalue = 0.906). CMT improved in ischemic group from 362.9 34.66 to 278.76 45.57 (pvalue< 0.001) and in non ischemic group from 353.47 67.61 to 239.87 55.44 (pvalue< 0.001). Conclusion: despite significant effect of intravitreal injection of bevacizumab in reducing of CMT in both ischemic and nonischemicgroupes. BCVA improved significantly in non ischemic group and no change in ischemic group. Keywords:Avastin, ischemic macular edema, nonischemic macular edema,diabetes
