highly vascularized layer of eyeball which lies between the retina and the sclera Its main function is to support the biological needs of the retina
The choroid is the posterior portion of the uveal tract and lies between the retina and the sclera It is darkly pigmented When the overlying sclera is thinned it is the colour of the underlying choroid which gives rise to the term 'blue sclera'
The tissue layer that sits just below the retinal pigment epithelial cells (RPE) The choroid is rich in blood vessels and connective tissue, and is a major supplier of oxygen and nutrients to the RPE and photoreceptor cells
{i} choroidea, choroid coat, membrane of the eye containing blood vessels (Ophthalmology)
Vascular (major blood vessel) layer of the eye lying between the retina and the sclera Provides nourishment to outer layers of the retina
resembling the chorion; as, the choroid plexuses of the ventricles of the brain, and the choroid coat of the eyeball
a pigmented tissue with a blood vessels network; part of the vascular coat between the sclera and retina
{s} pertaining to the chorion or structures which resemble the chorion (membrane which surrounds the fetus before birth)
the thin, blood-rich membrane that lies between the retina and the sclera; responsible for supplying blood to the retina
is a part of the uvea It runs from the ciliary body around the back of the eye between the retina and the sclera (see diag p 4) It is pigmented and is mainly made up of blood vessels which supply the retina
