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

    The cardinal funduscopic feature of malignant hypertension is optic disk swelling (seen in both images), 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.
