This chapter discusses how the anatomy and physiology of the lens change with age, the maintenance of lens transparency, and its associated factors, as well as the role of the lens in the refraction and accommodation of the eye, all of which will provide useful information for deciding on ...
Oculomotor.Fibers run from the midbrain to the eye; it supplies motor fibers to four of the six muscles (superior, inferior, medial rectus, and inferior oblique) that direct the eyeball; to the eyelid; and to the internal eye muscles controlling lens shape and pupil size. Trochlear.Fibers r...
The reality of them is a little less romantic. The eye isn't a single structure, but composed of many parts, including the retina, cornea, and sclera. The retina is a layer of nervous tissue in the interior of the eye, continuing into the cranium as the optic nerve. The white of the...

After passing through the iris, the light rays strike the eye’s crystalline lens. This clear, flexible structure works much like the lens in a camera – shortening and lengthening its width in order to focus light rays properly. In a normal eyeball, after exiting the back of the lens, th...
9) encompass not only ocular anatomy and physiology, but also incorporate clinical examination of the rabbit eye. Diseases are those likely seen in general practice, and where appropriate incorporate the treatments that a general practitioner can provide. Neurological and locomotor disorders (Ch. 10)...
