What are the functions of the choroid?

The choroid is a highly pigmented vascular layer located between the retina and the sclera in the eye. Its main function is to nourish and oxygenate the retina. The choroid contains a dense network of blood vessels that deliver nutrients and oxygen to the retinal cells, thereby supporting their metabolic needs. Additionally, the choroid absorbs excess light, helping to prevent reflections and glare that could impair vision. Furthermore, it plays a critical role in maintaining the temperature and pressure within the eye, which are essential for proper functioning. Overall, the choroid serves as a vital support system for the retina and contributes to the overall health and function of the eye.
