Choroidal neovascularization is discussed at length in Chapter 11 and in BCSC Section 12, Retina and Vitreous.
Figure 12-12 Iris neovascularization (rubeosis iridis). Tiny blood vessels sprout from existing iris vasculature, typically on the surface of the iris (black arrows). Note the flat anterior surface of the iris (A = anterior; P = posterior). The contractile component of the neovascular membrane may result in dragging of the iris pigment epithelium (red arrow) and sphincter muscle (green arrowheads) anteriorly at the pupillary margin, in turn resulting in ectropion uveae.
