Brief Summary:
The authors investigated the consecutive change of retinal vessel's diameter in affected eye and fellow eye of Branch Retinal Vein Occlusion.

Condition or disease
Branch Retinal Vein Occlusion

Detailed Description:
Twenty five consecutive patients who had undergone intravitreal bevacizumab injection for Branch Retinal Vein Occlusion with macular edema were included in this study. All subjects were enrolled between April, 2012 and April, 2013 in the Department of Ophthalmology, Kyungpook National University Hospital.

BRVO, Retinal vessel diameter
The retinal vessel diameter was measured Branch Retinal Vein Occlusion patients after intravitreal bevacizumab injection.

Primary Outcome Measures :
  1. Unoccluded retinal vessel diameter of Branch Retinal Vein Occlusion [ Time Frame: 0, 1, 3, and 6 months ]
    To evaluate the change of unoccluded retinal vessel diameter in affected eye of Branch Retinal Vein Occlusion and unaffected fellow eye.
