Multimodal imaging of an anomalous retinal vein

A 25-year-old female visited to the outpatient department for a routine checkup. On evaluation, her best-corrected visual acuity in right (OD) and left (OS) eyes was 20/120 and 20/20, respectively. Anterior segment examination revealed corneal opacity in OD, whereas OS was within the normal limits. Fundus examination was normal in OD, whereas OS showed an anomalous retinal vein adjoining the macula [Figure 1a]. Optical coherence tomography (OCT) of the OS macula revealed backscattering in the area beneath anomalous retinal vein [Figure 1b].Figure 1: (a) Branch of retinal vessels crossing over the parafoveal region in OS; (b) optical coherence tomography of the OS reveals backscattering in the area beneath anomalous retinal; (c and d) superficial (c) and deep (d) retinal layers showing the penetration of the vein across various layers; (e and f) Outer retina and choriocapillaries showing shadow of the vesselOCT angiography of the OS revealed anomalous vessels coursing through the superficial retina [Figure 1c and d] causing a back shadow in the deeper slabs [Figure 1e and f]. Retinal arteriovenous malformation and an anomalous retinal artery have been reported previously.[1,2] Herein, we report a unilateral anomalous retinal vein which is a rare, congenital, and asymptomatic clinical entity using multimodal imaging.
