a Left eye color fundus photograph of the posterior pole, showing widespread retinal opacification with a central cherry red spot at fovea. There is presence of box-caring and narrowing of arterioles. b, c Optical coherence tomography horizontal (b) and vertical (c) scans showing inner retinal layers hyperreflectivity, edema and loss of stratification with an localized shallow internal limiting membrane detachment with central foveal attachment. d, e Optical coherence tomography angiography superficial (d) and deep (e) capillary network. Pruning of both arteries and veins with significant capillary bed flow-void areas in the macular region. f Fundus fluoresceine angiography of recirculation phase showing washout of dye with significant central capillary filling defect resulting in enlargement of foveal avascular zone
