Spectrum of retinal microvascular ischemia in patients with COVID-19 based on multimodal imaging

Year: 2024

Type: article

Abstract: Purpose: To describe and evaluate the multimodal imaging findings in retinal microvascular ischemia associated with COVID-19 infection. Methods: was defined as the presence of isolated or multiple focal retinal whitening(s) on color fundus images. Patients with retinal vessel occlusion or retinopathies secondary to systematic disorders diagnosed before infection were excluded. Results: = 0.008). Transient uncontrolled high blood pressure or acute kidney injury was simultaneously detected in some cases. Conclusions: Ocular manifestation of COVID-19 associated microvascular ischemia can be variable, including CWS, PAMM and ASHH. Multimodal fundus imaging technologies are useful tools to reveal involved retinal layers, extent, and severity. Moreover, ocular manifestations may serve as a window of COVID-19 related microcirculation in other systems throughout the body.
