Abstract

Cette invention se rapporte à un procédé servant à traiter l'hypertension oculaire et les glaucomes et qui consiste à administrer en mode topique dans les yeux d'un sujet mammifère nécessitant un tel traitement plus de 5 νg et moins de 50 νg par oeil par administration d'un composé de 15-céto-prostaglandine comportant une structure cyclique à l'extrémité de la chaîne φ. Le traitement faisant l'objet de cette invention ne produit pour ainsi dire pas d'effets secondaires irritants l'oeil ou en produit à un niveau réduit, même à une telle dose élevée.
