The Diagnostic Value of Multispectral Fundus Imaging in Hypertensive Retinopathy

Abstract

Purpose: To observe the diagnostic value of multispectral fundus imaging (MSI) in hypertensive retinopathy (HR). Methods: A total of 100 patients with HR were enrolled in this cross-sectional study, and all participants received fundus photography (FP) and MSI. Participants with severe HR received fundus fluorescein angiography (FFA). The diagnostic consistency between FP and MSI in the diagnosis of HR was calculated. The sensitivity of MSI in the diagnosis of severe HR was calculated by comparison with FFA. Choroidal vascular index (CVI) was calculated in HR patients using MSI at 780 nm. Results: MSI and FP were highly concordant in the diagnosis of HR with a Kappa value = 0.883. MSI had a sensitivity of 96% in diagnosing retinal hemorrhage (RH), a sensitivity of 89.47% in diagnosing retinal exudation (RE), a sensitivity of 100% in diagnosing vascular compression indentation (VCI), and a sensitivity of 96.15% in diagnosing retinal arteriosclerosis (RA). The CVI of the patients in the HR group was significantly lower than that of the control group, whereas there was no significant difference between the affected and fellow eyes. Conclusion: As a noninvasive modality of observation, MSI may be a new tool for the diagnosis and assessment of HR.
