An agent for visualizing vitreous body which is to be injected into the eye to visualize the vitreous body by a safe and sure method. The agent for visualizing vitreous body is prepared by using a high-molecule substance having a positively or negatively charged functional group and adding a hardly water-soluble and nonsteroidal colored substance, in which the high-molecule substance is to be suspended, thereto. Because of having a nonsteroidal nature, it can be safely injected into the eye and the colored substance, in which the high-molecule substance is to be suspended, makes the vitreous body visually recognizable.

L'invention concerne un agent pour la visualisation du corps vitreux, destiné à être injecté dans l'oel pour visualiser le corps vitreux selon un procédé sans danger et sûr. On prépare l'agent pour la visualisation du corps vitreux en utilisant une substance de poids moléculaire élevé ayant un groupe fonctionnel positivement ou négativement chargé et en y ajoutant une substance colorée non stéroïdienne à peine hydrosoluble dans laquelle la substance de poids moléculaire élevé doit être en suspension. Du fait de sa nature non stéroïdienne, la substance peut être injectée sans danger dans l'oel et la substance colorée, dans laquelle doit être en suspension la substance de poids moléculaire élevé, rend le corps vitreux visuellement reconnaissable.
