Segmental reproducibility of retinal blood flow velocity measurements using retinal function imager.

Background: To evaluate the reproducibility of blood flow velocity measurements of individual retinal blood vessel segments using retinal function imager (RFI).

Methods: Eighteen eyes of 15 healthy subjects were enrolled prospectively at three centers. All subjects underwent RFI imaging in two separate sessions 15 min apart by a single experienced photographer at each center.

Comparative analysis of the retinal microvasculature visualized with fluorescein angiography and the retinal function imager.

Purpose: To assess the visualization of the retinal microvasculature with intravenous fluorescein angiography (IVFA) compared to the Retinal Function Imager (RFI).

Design: Multicenter, retrospective, observational case series.

Methods: Seven normal eyes and 26 eyes with various ocular diseases were imaged with both IVFA and the RFI.
