What is the choroid?

The choroid is a highly vascularized layer of tissue located between the retina and the sclera, the white outer layer of the eye. It plays a crucial role in nourishing and supporting the retina, which is responsible for visual perception. The choroid contains numerous blood vessels that not only supply oxygen and nutrients to the retina but also help regulate its temperature. Additionally, it contains pigmented cells that help absorb excess light and prevent reflections within the eye, thereby enhancing visual clarity. Disorders of the choroid, such as choroiditis or choroidal neovascularization, can result in vision problems and may require medical intervention to preserve eyesight.
