Anterior Chamber:@0:10
Depth:
→ Measurement from centre of cornea to centre of pupil.
→3 mm
→Shallow AC – women, elderly, children [WEC]
→Deep AC – young males
Volume:
→0.25 to 0.3 ml
→ Anterior chamber filled with aqueous humor
→ Provides nutrition to-
Avascular structures-cornea, lens.
Cornea Nutrition Supply:@1:47
→ Glucose → completely supplied by aqueous humor.
→O2 supplied by:
1.Air
2. Tear Film

Crystalline Lens
→Lens suspended by Zonules/ suspensory ligaments from ciliary body
→ Iris lens diaphragm includes:
1.Iris
2.Ciliary body
