    Hypertensive Retinopathy—Malignant (Star-Shaped Exudates and Papilledema)

    The cardinal funduscopic feature of malignant hypertension is optic disk swelling, which appears as blurring and elevation of disk margins. The top image also shows a characteristic star-shaped macular lesion caused by leaking retinal vessels. The bottom image also shows a characteristic flame-shaped hemorrhage and dilated veins.
