Abstract

Background: The present study was undertaken to compare pulsatile choroidal blood flow in patients with branch retinal vein occlusion (BRVO) with the values in normal controls. Methods: The study included male and female patients with manifest BRVO (n=16) and a healthy sex- and age-matched control group (n=36). Fundus pulsation amplitude (FPA) was measured in the fovea by laser interferometry to assess pulsatile choroidal blood flow. Results: The FPA in eyes with BRVO (4.4 μm) was significantly higher than in the fellow eye (3.8 μm; P<0.0005). There was also a significant difference between the affected eye of the patients and the healthy control group (3.3 μm; P<0.0009). Conclusion: The increase in FPA indicates increased choroidal blood flow resulting from some local mechanisms compensating for the decrease in retinal blood flow.
