"post-endovascular clot retrieval (1-2%) 3-5"

"Digital subtraction angiographic findings are those of non-invasive angiography, including non-opacification of the ophthalmic artery and/or other more proximal vasculature, depending on the cause 3-5. Post-endovascular clot retrieval, loss of normal choroidal blush, normally indicative of orbital perfusion, has been described as a highly sensitive sign for orbital infarction syndrome 3."
"Similar to CT, there may be proptosis and the extraocular muscles may be enlarged 3,9,10. Additionally, MRI may reveal high T2 signal affecting the optic nerve, optic nerve sheath, retina, extraocular muscles, and intraorbital fat 3,4,6,7,9,10. There may also be diffusion restriction of the optic nerve and retina 4,6,7,8. Angiographic findings are identical to those aforementioned on CT angiography 7."
"The clinical presentation is usually acute but can be progressive and subacute or chronic in tempo depending on the cause 1-9. Clinical features include ocular pain, monocular visual loss, complete ophthalmoplegia, proptosis, ptosis, chemosis, ophthalmoplegia, relative afferent pupillary defect, and retinal pallor 1-9. Intraocular pressure may also be raised 5."
"Similar to CT, there may be proptosis and the extraocular muscles may be enlarged 3,9,10. Additionally, MRI may reveal high T2 signal affecting the optic nerve, optic nerve sheath, retina, extraocular muscles, and intraorbital fat 3,4,6,7,9,10. There may also be diffusion restriction of the optic nerve and retina 4,6,7,8. Angiographic findings are identical to those aforementioned on CT angiography 7."
"All patients with suspected orbital infarction syndrome should have angiographic and orbital imaging performed. The below radiographic findings are of orbital infarction syndrome generally; additional findings may be present depending on the aetiology."
