A 32-year-old gentleman presented with sudden loss of vision in right eye (OD) since 3 days. Best corrected visual acuity (OD) was light perception. On examination, a pale retina with cherry red spot was noted suggestive of acute central retinal artery occlusion (CRAO). Swept-source OCT (Topcon DRI OCT Triton, Japan®) showed cystoid macular edema (CME) and neurosensory detachment (NSD) with hyperreflectivity in inner retinal layers. OCT angiography showed deficient capillary network with presence of void areas around the fovea in superficial, deep, and choriocapillaris layers. En-face OCT showed “petaloid” pattern of CME at junction of inner plexiform and nuclear layers [Figure 1]a, [Figure 1]b, [Figure 1]c, [Figure 1]e, [Figure 1]f. He underwent ocular massage, AC paracentesis, and oral acetazolamide 250 mg TDS with topical dorzolamide was prescribed for 5 days. Carotid Doppler showed 90% occlusion of right internal carotid artery with deranged serum lipids. At 1-week follow-up, there was no functional improvement; however, there was complete resolution of CME and NSD on B scan and en-face OCT [Figure 2]a, [Figure 2]b, [Figure 2]c, [Figure 2]d, [Figure 2]e, [Figure 2]f.

CRAO is a devastating event with grave prognosis presenting with cherry red spot and pale retina suggestive of diffuse intraretinal edema, mainly involving ganglionic cell layer. OCT angiography shows reduced capillary density in superficial and deep capillary plexus with relative sparing of outer retina and choriocapillaris., Presence of CME in acute CRAO usually indicates concomitant venous occlusion seen as tortuosity of veins with hemorrhages. An isolated case of acute CRAO with presence of CME is rare and indicates presence of outer retinal ischemia and compromise of outer blood–retinal barrier due to choroidal vascular insufficiency. Ng et al. reported case of CME with CRAO in a 76-year-old lady. However, there was no recorded follow-up regarding the course of CME. In our case, there was complete resolution of CME but there was no functional improvement.
