Bei der epiretinale Gliose handelt es sich um eine Gliose, bei der sich auf der Netzhautoberfläche, meist im Bereich der Makula, eine dünne Membran bildet. Diese faserhaltige Gewebeschicht kann zu einer Faltenbildung der Netzhaut und dadurch zu Metamorphopsien führen. Die epiretinale Gliose tritt ab dem 5.
