Anatomy of the eye pdf

Ledford, Ocular Anatomy and Physiology, Second Edition now begins with a jump-start chapter to overview the topic for those new to the field of eye care. Chapter two delves into embryology—a topic rarely covered—and addresses each structure of the eye, including the bony orbit, eyebrows, eye lids, lacrimal system, extraocular muscles, and the globe. While the text continues to emphasize normal anatomy, each chapter contains a glossary of common disorders.

Also included is a description of diagnostic methods for examining various tissues. The physiology of various structures and systems is explained, including the visual pathway, the inflammatory response, immunology, binocular vision, refractive errors, and accommodation.

To enhance the reader's understanding of each topic, illustrations are provided. Author by : A. Paul L. This full-color, user-friendly edition captures the latest molecular, genetic, and biochemical discoveries and offers you unparalleled knowledge and insight into the physiology of the eye and its structures.

And for medical students who are in their 1st and 2nd year of med-school, this subject is often regarded as exhausting and nerve-wracking.

You have to memorize very intricate details that are always easily forgotten i. But all of these books are good when you are starting out new in the academic year as they require plenty of time to be read, digested and retained.

Majority of these books cannot be studied during the exam seasons. In this article, we are going to share with you a clinical anatomy book that is both easy-to-read and retained. Not only that, you can also use this book while preparing for a major anatomy exam. The overall structural organization of its content and curriculum is very user-friendly and well-versed to the international standards.

Let us start from the outside and work our way toward the back of the eye. The eyelids protect and help lubricate the eyes. The eyelid skin itself is very thin, containing no subcutaneous fat, and is supported by a tarsal plate. This tarsal plate is a fibrous layer that gives the lids shape, strength, and a place for muscles to attach. Underneath and within the tarsal plate lie meibomian glands. These glands secrete oil into the tear film that keeps the tears from evaporating too quickly.

Meibomian glands may become inflamed and swell into a granulomatous chalazion that needs to be excised. A stye is a pimple-like infection of a sebaceous gland or eyelash follicle, similar to a pimple, and is superficial to the tarsal plate. Styes are painful, while chalazions are not. Eyelid Movement Two muscles are responsible for eyelid movement. The orbicularis oculi closes the eyelids and is innervated by cranial nerve 7.

The levator palpebrae opens the eye and is innervated by CN3. Oculomotor nerve palsy is the major cause of ptosis drooping of the eye. In fact, a common surgical treatment for ptosis involves shortening the levator tendon to open up the eye.

CN 3 opens the eye like a pillar CN 7 closes like a fish-hook. The conjunctiva is a mucus membrane that covers the front of the eyeball. The conjunctiva starts at the edge of the cornea this location is called the limbus.

It then flows back behind the eye, loops forward, and forms the inside surface of the eyelids. The continuity of this conjunctiva is important, as it keeps objects like eyelashes and your contact lens from sliding back behind your eyeball.Our eyes might be small, but they provide us with what many people consider to be the most important of our senses — vision.

Anatomy of the Eye: Human Eye Anatomy

How vision works Vision occurs when light enters the eye through the pupil. With help from other important structures in the eye, like the iris and cornea, the appropriate amount of light is directed towards the lens.

Just like a lens in a camera sends a message to produce a film, the lens in the eye 'refracts' bends incoming light onto the retina. The retina is made up by millions of specialised cells known as rods and cones, which work together to transform the image into electrical energy, which is sent to the optic disk on the retina and transferred via electrical impulses along the optic nerve to be processed by the brain.

Comparative Anatomy of the Eye. The Anatomy of the Eye and Orbit. Atlas of Eye Surgery and Related Anatomy. The anatomy and fine structure of the eye in teleosts.

It is composed of two spheres with different radii, one set into the other Figs and The front, or anterior, sphere, which is the smaller and more curved of the two, is called the cornea. The cornea is the window of the eye because it is a completely transparent structure. It is the more curved of the two spheres and sets into the other as a watch glass sets into the frame of a watch.

The cornea and the sclera are relatively nondistensible structures that encase the eye and form a protective covering for all the delicate structures within. In terms of size, the eye measures approximately 24 mm in all its main diameters in the normal adult. Surface anatomy The eye itself is covered externally by the eyelids, which are movable folds protecting the eye from injury and excessive light.

The upper eyelid extends to the eyebrow, which separates it from the forehead, whereas the lower eyelid usually passes without any line of demarcation into the skin of the cheek. The upper eyelid is the more mobile of the two and when it is open, it covers about 1 mm of the cornea.

A muscle that elevates the lid, the levator palpebrae superioris, is always active, contracting to keep the eyelid open. During sleep the eyelid closes by relaxation of this muscle. The lower lid lies at the lower border of the cornea when the eye is open and rises slightly when it shuts.

Normally, when the eyes are open, a triangular space is visible on either side of the cornea. These triangular spaces, formed by the junction of the upper and lower lids, are called the canthi Fig. These canthi are denoted by the terms medial and lateral, the former being closer to the nasal bridge. The free margin of each lid is about 2 mm thick and has an anterior and a posterior border. From the anterior, or front, border rise the eyelashes, which are hairs arranged in two or three rows.

The upper eyelid lashes are longer and more numerous than the lower and they tend to curl upward. The lashes are longest and most curled in childhood. The posterior border of the lid margin is sharp and tightly abuts against the front surface of the globe. By depressing the lower lid, one can see the thin gray line that separates the two borders of the lid. This gray line is used in many surgical procedures to split the upper and lower lids into two portions.

The largest oil-secreting glands, which are embedded in the posterior connective tissue substance of the lids called the tarsusare called the meibomian glands. The lacrimal gland is located above and lateral to the globe.
