BACKGROUND: The aim of this study was to evaluate the retinal safety profile of flow-diverting stents in the treatment of carotid-ophthalmic aneurysms with ophthalmic artery coverage.
METHODS: In this cohort study, patients treated with a flow-diverting stent for carotid-ophthalmic aneurysm were prospectively included from January 2021 to January 2023. A systematic ophthalmological examination was performed before and at 15 days and at 6 months after the procedure. We compared the retinal thickness and the vascular density of the retinal capillary plexuses using optical coherence tomography (OCT).
RESULTS: Twenty-five patients were included (median age: 52.3 years, range: 36.6 to 76.4; women: 92.4%). Postoperative retinal events were reported in 24% patients (cotton wool spots in 6 patients [24%], retinal hemorrhages in 3 patients [12.5%]), with no functional repercussions detected on examination. The macular vascular framework assessed by OCT-angiography remained unchanged postoperatively. We observed immediate postoperative foveal thinning and temporal papillary optic fiber thickening which was not clinically significant. After 6 months, all clinical events had resolved, and both macular and peripapillary OCT had returned to normal.
CONCLUSIONS: This study provides evidence for retinal safety when using flow-diverting stents covering the ophthalmic artery. Fundus changes may occur in the postoperative course, but without impact on visual function.
