A 58-year-old woman presented with sudden blurring of vision in OD for 15 days and in OS since 2 months. She was a known hypertensive and diabetic for past 10 years on insulin, on irregular treatment. Blood pressure (BP) noted was 160/100 mmHg, with HbA1c of 10.6 gm/dl. Best-corrected visual acuity (BCVA) was 20/200 in OD and 20/600 in OS. Anterior segment was unremarkable in OU. Fundus OD [Figure 1]a showed inferior hemi-retinal vein occlusion (HRVO). OS fundus [Figure 1]b revealed inferior hemi-retinal arterial occlusion (HRAO) with Hollenhorst plaque in infero-temporal artery (arrow, [Figure 1]b). Fundus fluorescein angiography (FFA) showed blocked fluorescence with perivascular leak and macular edema in OD [Figure 1]c and large areas of capillary non-perfusion in inferior retina and neovascularization of the disc (NVD) in OS [Figure 1]d. Swept-source optical coherence tomography (SS-OCT) showed intraretinal and subretinal fluid in OD [Figure 1]e and retinal atrophy in the inferior hemi-retina in OS with superior retina being normal [Figure 1]f. Patient was diagnosed to have inferior HRVO with macular edema in OD and old inferior HRAO with NVD in OS.

(b) Fundus photograph of OS showing Hollensorst plaque with sclerosed vessels with featureless retina suggestive of hemi-retinal arterial occlusion. (c) Fundus fluorescein angiography (FFA) of OD showing leakage in the inferior retina around the veins suggestive of increased permeability of vessels and retinal edema. (d) FFA of OS showing inferior capillary non-perfusion (CNP) area with macular involvement with hyperfluorescence at the disc suggestive of neovascularization of the disc (NVD). (e) Optical coherence tomography (OCT) of OD showing cystic spaces within the retinal layers and well-defined neurosensory detachment (NSD). (f) OCT of OS showing loss of architecture and atrophy of macular area with no well-defined foveal region|

Complete systemic workup was done for metabolic control and to rule out any source of emboli. Intravitreal bevacizumab was given in OD and inferior scatter laser was performed in OS. On last follow-up, patient had a vision of 20/60 in OD with no macular edema and vision in OS was 20/200 with regressed NVD.
| Discussion|| |
Retinal vein occlusion (RVO) is the most common retinal vascular disorder following diabetic retinopathy (DR). Age, systemic hypertension, and diabetes mellitus (DM) are the common risk factors for both RVO and retinal arterial occlusion (RAO)., Proportion of HRVO, branch retinal vein occlusion (BRVO), and central retinal vein occlusion (CRVO) is 60%, 54%, and 49%, respectively, in patients with age >65 years. Only a handful of cases of HRAO are described in the literature so far., HRAO is seen in eyes with proximally bifurcated central retinal artery along with underlying systemic conditions. This case highlights the different manifestations of similar underlying risk factors in two eyes of the same patient.
