ANATOMY OF THE HUMAN EYE

Anatomy of the eye includes lacrimal gland, cornea, conjunctiva, uvea (iris, choroid & ciliary body), lens, blood supply, retina, vitreous & optic-nerve. For ophthalmologists, optometrists, medical, dental, and optometry students, eye-anatomy forms the basis for eye-pathology in diseases: dry eye, retinal detachment, macular degeneration, diabetic retinopathy, eye-trauma etc.

EYE-MICROSCOPIC-SECTION-LABELED




CLICK ON THE PHOTO TO ENLARGE AND SEE THE ANSWERS.
This photo is convenient to study the flow of aqueous from the ciliary epithelium of the ciliary body through the posterior chamber and the narrow space between the iris and lens into the anterior chamber and then in the anterior chamber angle and trabecular meshwork, Schlemm's canal and the collector vessels. Anatomic pertubations that may obstruct this flow include apposition of peripheral iris against the cornea (known as angle closure glaucoma), apposition of the iris against the lens because of rotation of the ciliary body leading to (malignant glaucoma), obstruction of the trabecular meshwork (such as in hemorrhage known as ghost cell glaucoma), adherence of the pupillary margin of the iris to the lens as after severe inflammation), and back pressure on the system such as a tumor that obstructs aqueous veins or a carotid cavernous sinus fistula that produces elevation of venous pressure and blood can sometimes be seen in aqueous veins.
