Automated algorithm to measure iris vessels volume in patients with acute anterior uveitis. A 3 × 3 OCT angiogram of the nasal iris of a patient with 3+ anterior chamber cells is shown in panel a. A 3D cube is processed using a combination of 3D Gaussian filters, spectral bandpass filters, intensity thresholding, and 3D morphological “opening” filters to remove non-specific, non-contiguous voxels (b). Connected voxels represent vessel segments. Vascular volumes were subsequently calculated by summing voxels in the resulting vessel masks (c, d)
