Note that the lensis opaque-white, an artifact of preservation. The posterior cavity is filled with clear jelly-like vitreous humor . Note the three tunics of the wall of the eye:
fibrous tunic (sclera plus cornea)
vascular tunic (iris, ciliary body and choroid)
Here is a labeled image of the components of the eye (upper image in left frame).
The fovea centralis will be towards the center and seen as a yellowish depression. (Here is a labeled image.)
The retina peels away easily from the underlying choroid. This, adetached retina is a serious condition requiring immediate attention in patients to prevent death of the retina and blindness in the patient.
In the anterior portion of the eye, note that the lens is supported by suspensory ligaments. Posterior to it is the ruffled surface of the black pigmented ciliary processes which produce the aqueous humor.
The ora serrata is the anterior boundary of the retina. The iris is golden on the exterior surface, black on the posterior. The cornea is tough and relatively thick.
