t makes sure that the eye stays in place.
That is a horrible answer with no truth to it at all. The choroid is a layer of the eye deep to the retina and superficial to the sclera. It provides oxygen and nutrients to the retina through its extensive network of capillaries. The retina itself does not have a huge vascular supply, because the vessels would interfere with the formation of the image in the eye. This is why the choroid is necessary.
The choroid is also very heavily pigmented due to an abundance of melanin. This increased pigment allows the choroid to absorb excess light and minimize reflections within the eye.
The choroid along with the iris and ciliary body make up what is known as the uveal tract.

No, the choroid is not the pigmented layer of the eye. The pigmented layer is called the retina, specifically the pigmented epithelium layer of the retina. The choroid is a vascular layer located behind the retina that provides oxygen and nutrients to the retina.

Choroid cysts primarily occur in the eye, specifically in the choroid layer of the eye, which is located between the retina and the sclera. However, similar cystic structures can also appear in other parts of the body, such as the brain (e.g., choroid plexus cysts). While the term "choroid cyst" is most commonly associated with the eye, it's important to recognize that cysts can form in various tissues and organs.
