Purpose:
|
To report the complications of various types of RVO and their difference between patients with and without history IVB injection.
|
|
Methods:
|
Retrospective study.
|
|
Results:
|
110 patients were included: 41 ischemic CRVO, 25 non-ischemic CRVO, and 44 BRVO cases, followed for 8-36 months and mean age of 59.24±14.75. Sixty patients had history of IVB (mean: 1.8). Macular edema (70%), vitreous hemorrhage (26%), and neovascular glaucoma (19.3%) were the most common complications. There were no differences in complications between various types of RVO except for less vitreous hemorrhage (p=0.017) and more neovascular glaucoma (p=0.015) in ischemic CRVO.
Injection caused reduction in macular edema in all types of RVO (p<0.05). Neovascular complications increased during the study period in eyes with ischemic (p= 0.014) and non-ischemic (p=0.046) CRVO without history of IVB but not in those with history of IVB (p>0.05). IOP and VA were not different between various types of RVO and between patients with or without injection.

|
Conclusion:
|
Eyes with ischemic CRVO more commonly developed neovascular glaucoma and less commonly developed vitreous hemorrhage. Bevacizumab injection caused a decrease in macular edema in all types of RVO, which was not accompanied by an increase in visual acuity. Injection also prevented development of neovascular complications in CRVO.
