Rubeosis iridis. Rubeosis iridis. Other names. Neovascularization of the iris. Specialty. Ophthalmology. Rubeosis iridis is a medical condition of the iris of the eye in which new abnormal blood vessels (formed by neovascularization) are found on the surface of the iris. [1]
Eye color. Eye color is a polygenic phenotypic trait determined by two factors: the pigmentation of the eye 's iris [1] [2] and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. [3] : 9. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of ...
