    摘要: Proliferation of retinal pigment epithelium following surgery or trauma is prevented by contacting retinal pigment epithelium cells with a therapeutic amount of a retinoic acid receptor (RAR) agonist, preferably one with specific activity for retinoic acid receptors. Preferably the RAR agonist is also a potent antagonist of AP1-dependent gene expression. Alternatively, the proliferation of retinal pigment epitelium is ameliorated witha therapeutic amount of an AP-1 antagonist, alone or in combination with an RAR agonist. The drug can be administered by bolus injection into the vitreous cavity using a dosage from about 50 to 150 .mu.g, or by slow release from liposomes or an oil tamponade injected into the vitreous cavity. Formulations for preventing proliferation of retinal pigment epithelium are also provided.
