BACKGROUND AND PURPOSE: Flow-diverting stents can be used to treat intracranial aneurysms that are not amenable to treatment with coils. We analyzed ophthalmic consequences due to coverage of the origin of the ophthalmic artery by flow-diverting stents for the treatment of internal carotid artery aneurysms.

In vitro 7-T MRI of keratinocytic skin cancer allows delineation of lesions with good correlation with histopathology. After in vivo confirmation it could have a diagnostic role regarding the delineation of surgical margins but its actual limitations prevent its practical adoption at this time.

Purpose To evaluate the ocular complications after insertion of a flow diverter " pipeline embolization device" (PED) to treat carotid‐ophtalmic artery aneurysms. PED is an endovascular implant designed as a stent to alter blood flow into the aneurysm. Therefore it may decrease the blood flow in the ophtalmic artery, and induce ophtalmological complications. Methods 22 patients suffering from carotid‐ophtalmic artery aneurysm, treated by flow diverter were included. Every patient underwent retrospectively a complete ophtalmological examination including macular and optic disc OCT and visual field. Results Among those 22 patients, 12 (54%) reported fonctional troubles: decreased visual acuity (6 patients), visual field loss (1), diplopia (1), amaurosis (1), photopsia or myodesopsia (3). 5 (23%) had clinical lesions: optic atrophy (3), distal embolism (2). No patient presented optic nerve compression after embolization as checked on MRI. Conclusion After flow divertion insertion, ophtalmological complications are frequent and various. Ophtalmological complications are rather due to ischaemia than compression, and may lead to optic atrophy and loss of vision. However a majority of patients recover normal visual function
