  • Publication number: 20230071741
    Abstract: The present invention relates to an ultrasound contrast agent for use in treating a retina disorder by transiently disrupting the blood-retinal barrier (BRB) of a human, wherein the ultrasound contrast agent is administered just before and/or during the application, to the retina of the human, of an unfocused ultrasound (US) beam. The present invention further relates to a therapeutically active agent for use in treating a retina disorder in a human, wherein the therapeutically active agent is to be delivered in combination with an ultrasound contrast agent, which is administered before and/or during the application, to the retina of the human, of an unfocused ultrasound (US) beam in order to transiently disrupting the blood-retinal barrier (BRB) of the human, to allow the therapeutically active agent to cross the BRB and to target the retina. The present invention also relates to an eye ultrasound delivery device that may be used to treat a retina disorder.
