OCT scans in a case of acute moderate CRAO: Fig. 3A: The right eye OCT scan in a case of acute CRAO at five-day interval from the onset of visual symptoms shows the opacification and thickening of the inner retinal layers (white arrow) with the presence of inner retinal hyporeflective fluid filled cavities (orange arrow) and small pocket of neurosensory detachment (red arrow) and prominent hyperreflectivity at the fovea. The retinal layer stratification is still intact. These OCT features are suggestive of a moderate variety of acute CRAO. In addition, a portion of the OCT scan appears normal on the temporal aspect of the optic disc on the papillomacular bundle suggesting of a patent cilioretinal artery (yellow arrow). Fig. 3B: On day 9, post presentation of symptoms, the OCT scan shows reduction in inner retinal layer opacification with middle retinal layer opacification being prominent. The inner retinal edema and neurosensory detachment have resolved and a normal foveal contour has been achieved. Fig. 3C and D: On days 18 and 58 post presentation of symptoms, there is extensive thinning of the inner retinal layers with intact stratification of the individual retinal layers
