Hierarchical clustering of 5 key optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) measurements (horizontal dendrogram) and clinical characteristics (vertical dendrogram) showed that data clustered into 3 groups. Mild visual field defect is defined as mean deviation between −2.0 dB and −5.0 dB and moderate to severe visual field defect is defined as mean deviation worse than −5.0 dB. In the annotation to the right of the heatmap, the colors are defined by the legends on the far right. Abbreviations: Ave = average; Disc = optic disc; GCC = ganglion cell complex; Mac = macular; MD = mean deviation; mod/severe = moderate to severe; OCT = optical coherence tomography; OCTA = optical coherence tomography angiography; PSD = pattern standard deviation; RNFL = retinal nerve fiber layer; VAD = vessel area density; VCI = vessel complexity index; VD = vessel diameter; VF = visual field; VPI = vessel perimeter index; VSD = vessel skeleton density.
