What are the Sources of Nutrients of Cornea?

Sources of Nutrients of Cornea:

1) Oxygen for the endothelium comes from aqueous humour and for epithelium from atmosphere through tear film. A small amount of oxygen is also provided to the peripheral parts of the cornea by the limbal capillaries and capillaries of the palpebral conjunctiva, especially during phases of eye closure.

2) The main source (90%) of glucose is aqueous humour. The remaining 10 per cent is provided by the lirnbal blood vessels and the tear film.

3) Amino acids come through aqueous humour by passive diffusion.
