    Adaptive optics assisted visualization of thickened retinal arterial wall in a patient with controlled malignant hypertension by Arichika S, Uji A, Yoshimura N

    Published 2014-10-01
    “…Shigeta Arichika, Akihito Uji, Nagahisa Yoshimura Department of Ophthalmology and Visual Sciences, Graduate School of Medicine, Kyoto University, Kyoto, Japan Purpose: We aimed to visualize the retinal arterial wall thickness, assisted by noninvasive adaptive optics scanning laser ophthalmoscopy (AO-SLO).Methods: The arterial wall thickness was measured and compared between one normal subject and one patient suffering from malignant hypertensive retinopathy.Results: Increased arterial wall thickness was revealed with a newly developed AO-SLO system, in a retinal artery of 1-papilla diameter temporal inferior to the optic disc. …”
