Study Notes
Eye Structures and Functions
- The trabecular meshwork actively pumps fluid out of the substantia propria to prevent over hydration and opacity.
Retinal Layers
- The retinal pigment epithelium (RPE) separates the retina from the choroid and contains a layer of pigmented epithelial cells on a basement membrane called Bruch's membrane.
Accessory Structures
- The function of accessory structures of the eye is to support and protect the eye.
- The conjunctiva, an accessory structure, produces mucus to lubricate and moisten the eye.
Ciliary Body and Processes
- The ciliary body produces the aqueous humor and maintains the shape of the lens.
- The function of the ciliary processes is to produce the aqueous humor.
Aqueous Humor
- The composition of the aqueous humor includes water, ions, sugars, and ascorbic acid.
Photoreceptors
- The primary function of rods and cones is to convert light into electrical signals that are transmitted to the brain.
Uveal Tract
- The choroid, a layer of the eye, contains numerous large melanocytes that absorb light and prevent interference from refraction.
