    Retina/Vitreous

    Retinal cavernous hemangioma. A, Fundus photograph of the left eye shows a retinal cavernous hemangioma in the temporal retina. B, These tumors characteristically appear as a grape-like saccular cluster of dark intraretinal venous aneurysms (arrowheads), typically located along the course of a retinal vein, without a feeding artery. White, fibroglial tissue is commonly present on the tumor surface (arrow), suggesting previous vitreous or preretinal hemorrhage. C, Early fluorescein angiography typically shows the very slow appearance of dye within the venous aneurysms. D, The tumor eventually fills with dye, without leakage. E, Fundus photograph of the right eye in a 12-year-old boy shows a larger characteristic retinal cavernous hemangioma in the temporal retina. F, Fluorescein angiography image of this tumor also demonstrates late filling of the intraretinal venous aneurysms, without leakage of dye.
