Rubeosis Iridis is a medical condition of the iris in which new abnormal blood vessels are found on the surface of the iris. It is usually a result of an retinal ischemic process such as; Vein Occlusions, Proliferative Diabetic Retinopathy, or Ocular Ischemic Syndrome. Whenever a patient develops rubeosis they usually develop Neovascular Glaucoma. Neovascular Glaucoma is where there are neovascularization (new blood vessels) that grow into the angle known as the Trabecular Meshwork which can cause the intraocular pressure to elevate significantly.
This image was documented using the Heidelberg HRA during Fluorescein Angiography of the retina. To focus on the iris I backed the camera system out and set the focus around +30-40diopters to get the iris in focus.
