 A. One CRAO patient with leopard print fundus showed no typical cherry-red spots. OCT indicated that the choroid was significantly thinner (yellow arrowheads). B. One patient presented 1 h after the onset of CRAO without cherry-red spots. Yellow‒white arterial emboli (the yellow arrowhead) could be seen in the superior temporal branch artery. OCT indicated that there was no obvious inner hyperreflexia. C. One CRAO patient combined with RVO showed no cherry red spots. Massive retinal haemorrhage could be seen in the fundus. OCT showed obvious inner retinal thickening and segmental increased reflection in the inner and outer reticular layers of the macular area (the red arrowheads) that manifested as acute para central middle maculopathy lesions. D. One CRAO patient with ciliary retinal artery perfusion showed no cherry red spots. OCT indicated a dividing line between the ciliary retinal artery perfusion area and infraction area. E. One CRAO patient with unknown macular oedema showed no cherry red spots. F. One CRAO patient with diabetes retinopathy showed no cherry red spots (the OCT scanning area was the centre of the macula). It was mistaken for macular haemorrhage. OCT showed cystoid macular oedema and obvious inner retinal thickening and high reflection
