Cornea

 


Eye anatomy

 

This is the anterior 1/5 of the sclera which is transparent. It is completely avascular. It is covered in front by a squamous stratified epithelium which is called Bowman's membrane. Its underlying main structure is the substantia propria which consist of dense fibrous tissue. Posterioly is the Descement's membrane of the posterior elastic membrane. It is attached to the front of the iris which is formed by the ligamentum pectinatum. The canal of Schlemm or the sinus venosus sclerae marks the corneoscleral junction. Its two main membranes are

The cornea houses the iris which in turn controls the light aperture to the eye called the pupil.

Bowman's membrane - this is the most external portion of the cornea

Descemet's membrane- this is the posterior membrane of the cornea.

Arteries and veins
The eyeball is supplied by long and short ciliary arterial branches of the ophthalmic artery and drained by the veins which drain into the superior and inferior ophthalmic veins.

Nerves
Long ciliary nerve which is a branch of nasociliary nerve (from the ophthalmic division of trigeminal nerve) and short ciliary nerves which passes through the ciliary ganglion.
