II. Definitions

  1. Choroid
    1. Thin layer of vascular pigmented tissue between Sclera and Retina
    2. Vascular supply for outer Retina photoreceptor cells
      1. In Retinal Detachment, the photoreceptor cells lose Choroid supply and become hypoxic
      2. Other parts of the Retina are supplied by the central Retinal artery

Definition (NCI_NCI-GLOSS) A thin layer of tissue that is part of the middle layer of the wall of the eye, between the sclera (white outer layer of the eye) and the retina (the inner layer of nerve tissue at the back of the eye). The choriod is filled with blood vessels that bring oxygen and nutrients to the eye.
