layer is retina, which is an extension of central nerve system and responsible for the
transduction of visual signal into neural signal. The intraocular components include
aqueous humor, lens and vitreous body. The lens is connected to ciliary body by
the zonules. Aqueous humor and vitreous body locate in front and back of the lens
(Fig. 1.1).
The eye is a very special organ. The optical media, including cornea, aqueous
humor, lens and vitreous, are transparent. This character allows light getting into
the innermost layer, retina, and also allows visualization of retinal structure using
various instruments, including optical coherence tomography.
