Computer versus human-expert ranking of posterior pole vascular tortuosity and dilation using retinal vessel maps generated from bedside optical coherence tomography: a proof-of-concept study.

Semiautomated computer software (ie, ROPtool) can trace and analyze optical coherence tomography (OCT)-generated retinal vessel maps for plus/pre-plus disease with high reliability and accuracy. This proof-of-concept study found that ROPtool can reliably rank OCT-generated vessel maps for tortuosity and combined tortuosity/dilation, which correlated well with human-expert rankings and clinical examination.
