Expert Answer:

 

Vitreous humour is in contact with the retina and helps to keep it in place by pressing it against the choroid.It contains very few cells mostly phagocytes which remove unwanted cellular debris in the visual field, as well as the hyalocytes of Balazs, which reprocess the hyaluronic acid.

The main function of  aqueous humour is to provide diopteric power to the cornea.

Its other functions include :-

  • Maintains the intraocular pressure and inflates the globe of the eye.
  • Provides nutrition (e.g. amino acids and glucose) for the avascular ocular tissues; posterior cornea, trabecular meshwork, lens, and anterior vitreous.
  • Carries away waste products from metabolism of the above avascular ocular tissues.
  • May serve to transport ascorbate in the anterior segment to act as an anti-oxidant agent.
  • Presence of immunoglobulins indicate a role in immune response to defend against pathogens.
  • Maintains proper brain energy consumption.
