The choroid is a vascular (blood vessel–rich) layer inside the eye. It sits between the retina and the sclera (the white outer coat of the eye). Its main role is to supply oxygen and nutrients to parts of the retina involved in vision. In eye care, the choroid is commonly discussed in retinal imaging, diagnosis, and treatment planning.
