Choroidal metastasis represents the most common malignant intraocular tumours.The objective of this study is to detect the structural and vascular features of choroidal metastasis by multimodal imaging.Sixteen eyes of 16 patients with choroidal metastasis were enrolled in this prospective study. The multimodal imaging was performed in all patients: fluorescein angiography, indocyanine green angiography, enhanced depth imaging optical coherence tomography (EDI-OCT), OCT angiography (OCTA), and ultrasonography.The choroidal metastasis was located in the macula region in 9 eyes (57%) and in the extramacular region in 7 eyes (43%). EDI-OCT showed a mean thickness of 950 ± 246 µm, a smooth anterior tumour surface in 5 eyes (31%), and a lumpy bumpy appearance in 11 eyes (69%). The most frequent EDI-OCT features were represented by choriocapillaris thinning (100%), shaggy photoreceptors (82%), subretinal fluid with speckles (69%), subretinal lipofuscin pigment (6%), absence of drusen (100%), optical shadowing (94%), low-internal optical reflectivity (75%), and retinal pigment epithelium alterations (43%). OCTA revealed an absence of intratumoral vascular network in all cases.The multimodal imaging contributed to greater insights into the anatomical and vascular features of choroidal metastasis. It allows for the collection of useful information to establish an appropriate diagnosis and follow-up.
