At the lower margin of the disc the new growthof vessels continues into the disc and then extends partly intothe retina. One very large vessel can be followed along thecourse of a posterior ciliary nerve into the choroid where itbranches, one branch passing backward into the disc. In thedisc the growth forms a fairly well defined nodule. The re-mainder of the disc shows simple oedema with some hem-orrhages, as does the retina around it. Near the disc the retinais separated from the choroid by albuminous coagulum. Withinthe nodule the fibrillar tissue of the disc has been largely re-placed by hyaline connective tissue, remains of the original. Fig. 7.—Vessel of angioma replacingstriated muscle fiber.
