Abstract
Purpose:
To evaluate retinal blood flow velocities in patients with retinal vein occlusion (RVO) by using Retinal Function Imager (RFI).
Methods:
Seventeen patients with unilateral retinal vein occlusion underwent testing with the RFI in both eyes. Mean arterial and venous blood flow velocities in the eyes with RVO were compared to the velocities in fellow, unaffected eyes.
Results:
In the eyes with retinal vein occlusion, mean arterial and venous blood flow velocities were measured as 3.09±1.45 mm/sec and 2.54±1.02 mm/sec, respectively. When compared to fellow normal eyes (4.42±1.79 mm/sec for arteries and 3.38±0.64 mm/sec for veins), both arterial and venous velocities were found to be significantly reduced (p=0.042 for arterial and p=0.018 for venous blood flow velocity).
Conclusions:
Reduced retinal blood flow velocities in the eyes with retinal vein occlusion may serve as a new parameter for evaluation of patients with retinal vein occlusion.
