Purpose: To determine the clinical outcome of intravitreal bevacizumab injection in patients with ischemic central retinal vein obstruction (CRVO). Methods: The present study was conducted retrospectively on 56 eyes of 56 patients who were diagnosed with CRVO and classified according to ischemic and non-ischemic type and underwent an intravitreal bevacizumab injection. The present study measured changes in visual acuity and central macular thickness, neovascularization in the anterior segment,

Results: The average number of bevacizumab injections in both groups was 2.07 and 1.62 in the ischemic type. No patients developed neovascular glaucoma in the non-ischemic type group, 14 of 26 eyes in the ischemic type group developed neovascular glaucoma and the mean time to diagnosis was 28.75 weeks. log MAR visual acuity of the ischemic type group prior to injection was 1.56 ± 0.65 on average which improved to 1.44 ± 0.97 (p = 0.45). Conclusions: Intravitreal bevacizumab injection improves the condition of cystic macular edema clinically, but does not affect the development of neovascular glaucoma and improvement of visual acuity in ischemic type CRVO.
