[Retinopathy associated with thrombotic microangiopathy of mixed origin (case report)]

This article presents a clinical case of ocular thrombotic microangiopathy of mixed origin (antiphospholipid syndrome, malignant arterial hypertension, multigenic thrombophilia). Multimodal imaging of the fundus provides a detailed assessment of its structures. Pathological changes in the choroid, the "retinal pigment epithelium - Bruch's membrane" complex, and the neurosensory retina, identified using fundus photography, short-wavelength autofluorescence, optical coherence tomography (OCT), and OCT angiography, are described as nonspecific in nature. Given the verification of renal thrombotic microangiopathy by nephrobiopsy in this clinical case, the likely pathogenic mechanism underlying the observed chorioretinopathy manifestations is chronic ocular thrombotic microangiopathy.
