UNLABELLED: Purpose To describe the multicolour imaging (MI) findings in superficial and deep vascular plexus occlusions.
METHODS: In this retrospective observational study, patients diagnosed with central retinal artery and branch retinal artery occlusion, cotton-wool spot, paracentral acute middle maculopathy and acute macular neuroretinopathy between January 2018 and June 2019 were included. Colour fundus photograph, optical coherence tomography and MI of these patients were analysed.
RESULTS: A total of 41 eyes of 40 patients were included in this study. In eyes with central retinal artery occlusion, MI showed white areas in the retina with orange foveal centre. In eyes with branch retinal artery occlusion, MI showed white area along the affected retinal quadrant without an orange foveal centre. In pure superficial vascular plexus occlusions as in cotton-wool spots, the lesion was identified on MI as a white lesion. On MI, paracentral acute middle maculopathy showed parafoveal white areas with orange foveal centre while acute macular neuroretinopathy on MI parafoveal greyish-white areas with normal foveal centre.
CONCLUSION: En-face images using MI technology can provide yet another way to identify the level of retinal vasculature involvement which complements the existing gold standard of optical coherence tomography imaging.
