What kind of nutrients does the aqueous humor have?
amino acids, glucose, and vitamins.
What part of the eye are the nutrients for?
the avascular eye tissues that include the lens, epithelium of the posterior surface of cornea, trabecular meshwork, anterior vitreous surface..
What are the avascular eye tissues?
the lens, epithelium of the posterior surface of cornea, trabecular meshwork, anterior vitreous surface..
What removes waste from the avascular eye tissues?
the aqueous humor.
What is the aqueous humor composed of?
plasma but with less protein.
Where does the aqueous fluid drain into?
The schlemm canal and then into the systemic venous circulation.
Where is the vitreous humor located?
occupies the entire space between the lens and retina of the eyeball.
What membrane surrounds the vitreous?
