Sure, here are the matches for the features of the eye with their functions:

1. Fovea Centralis: This is the part of the eye located in the center of the macula region of the retina. It is responsible for sharp central vision, which is necessary for activities where visual detail is of primary importance, such as reading and driving.

2. Optic Disc: This is the point of exit for ganglion cell axons leaving the eye. Because there are no retinal cells there, it corresponds to a small blind spot in each eye. The optic disc is also the entry point for the major blood vessels that supply the retina.

3. Scleral Venous Sinus (also known as Canal of Schlemm): This is a circular channel in the eye that collects aqueous humor from the anterior chamber and delivers it into the bloodstream. It helps regulate intraocular pressure.

4. Choroid Coat: This is the vascular layer of the eye, containing connective tissues, and lying between the retina and the sclera. The choroid provides oxygen and nourishment to the outer layers of the retina.

5. Ciliary Body: This is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor. The ciliary body is part of the uvea, the layer of tissue that delivers oxygen and nutrients to eye tissues.
