Methods and compositions are disclosed for treating a patient suffering from a condition associated with a retinal and/or choroidal disease or disorder of the eye involving endothelial cell dysfunction, especially vascular endothelial cells of the eye, and especially before or in the absence of neovascularization. The therapeutic method involves administering a tetracycline, an analog of tetracycline, or a chemically modified tetracycline (CMT) to a patient suffering from such conditions. Also provided are compositions and methods for reducing breakdown of tight junctions in vascular endothelial cells; reducing IL-1 a concentrations; and inhibiting IL-1 a-mediated matrix metalloproteinase activity in endothelial cells of the eye and surrounding tissues.

La présente invention se rapporte à des méthodes et à des compositions destinées à traiter un patient atteint d'un état pathologique associé à une maladie ou affection oculaire rétinienne et/ou choroïdienne caractérisée par une dysfonction des cellules endothéliales, en particulier des cellules endothéliales vasculaires de l'oeil, et notamment avant l'apparition de la néovascularisation ou en l'absence de néovascularisation. La méthode thérapeutique selon l'invention consiste à administrer une tétracycline, un analogue d'une tétracycline, ou une tétracycline chimiquement modifiée (CMT), à un patient atteint d'un tel état pathologique. L'invention concerne également des compositions et des méthodes permettant de réduire la rupture des jonctions serrées dans les cellules endothéliales vasculaires, de réduire les concentrations de IL-1a, et d'inhiber l'activité des métalloprotéinases matricielles induite par IL-1a dans les cellules endothéliales de l'oeil et les tissus environnants.
