Anatomy Of The Eye Glaucoma

This fluid known as the aqueous humor. Learn how the eyes drainage system relates to the development and treatment of glaucoma.

Pin On Glaucoma

Understand the Eye to Understand Glaucoma Covering most of the outside of the eye is a tough white layer called the sclera.

Anatomy of the eye glaucoma. Open-angle glaucoma is the most common form of the disease. Glaucoma is mainly to do with the fluid in the eye called aqueous humour not being able to drain away properly. Provides support to the retina and functions as the basement membrane of the RPE layer.

Glaucoma tends to run in families. Cornea - The cornea is the clear dome-like structure on the front part of the eyeThe cornea delivers 23 of the refracting power to the eye. Glaucoma is usually but not always associated with elevated pressure in the eye intraocular pressure.

This causes pressure in the eye to gradually increase. In some cases glaucoma may occur in the presence of normal eye pressure. The only way to find out if you have glaucoma is to get a comprehensive dilated eye exam.

The drainage angle formed by the cornea and iris remains open but the trabecular meshwork is partially blocked. Part of the eye above the lens that produces the aqueous humor. Drainage system of the eye.

Review the normal anatomy and physiology of the eye as well as the changes that occur in the drainage of aqueous humour with glaucoma. Phacolytic glaucoma PG is a form of glaucoma which is caused due to a leaking mature or immature cataract. It gets worse over time.

Part of the white sclera can be seen in the front of the eye. It allows light to enter the eye. In all forms of glaucoma the status of the eyes drainage system the trabecular meshwork is important.

Structure anatomy of your eye You can learn more about how the eye works and the structure of the eye in the separate leaflet called Anatomy of the eye. Inflammatory glaucoma which occurs in phacolysis is a condition which is a result of the leakage of protein within the lens into the capsule of a mature or hyper mature. Providing Information about Glaucoma Nursing Interventions.

Pressure inside the eye. A clear delicate membrane called the conjunctiva covers the sclera. Sclera - The sclera is the white tough outer covering of globe of the eye.

Glaucoma is a condition that damages your eye s optic nerve. Secondary glaucoma Can medications cause glaucoma. A clear thin layer called the conjunctiva covers the sclera.

Just like an eggshell surrounds an egg and gives an egg its shape the sclera surrounds the eye and gives the eye its shape. To understand what causes glaucoma you first must know something about the human eyes anatomy and how intraocular fluid moves through the eye. Glaucoma is a group of eye diseases that can damage the optic nerve and result in vision loss and blindness.

These muscles pull on the sclera causing the eye to look left or right up or down and diagonally. Generally it is this elevated eye pressure that leads to damage of the eye optic nerve. The symptoms can start so slowly that you may not notice them.

This pressure damages the optic nerve. Its often linked to a buildup of pressure inside your eye. The dark center opening in the middle of the iris.

At the very front of the eye is a clear surface like a window called the cornea that protects the pupil and the iris behind that window. The clear fluid inside the eye is produced by the ciliary body which is a small circular structure found behind the iris or colored portion of the eye. The cornea is the clear part of the eyes protective covering.

Anatomy of glaucoma There are several different types of glaucoma all characterized by damage to the eyes optic nerve which connects the retina to the brain. The extraocular muscles attach to the sclera. Open-angle glaucoma Open-angle glaucoma is by far the most common form of the disease.

New drugs on the horizon may directly target. Nursing Diagnoses Deficient Knowledge about glaucoma and surgical procedure Goal. The pupil changes size to adjust for the amount of light available smaller for bright light and larger for low light.

This contact may gradually damage the draining function of the meshwork until it fails to keep pace with aqueous production and the intraocular pressure rises. In angle-closure glaucoma also closed-angle glaucoma primary angle-closure glaucoma acute glaucoma the iris bows forward and causes physical contact between the iris and trabecular meshwork which blocks the outflow of aqueous humor from within the eye. Secondary glaucoma Can diabetes cause glaucoma.

Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging a nerve in the back of your eye called the optic nerve. Glaucoma is one of the most common eye conditions related to optic nerve damage. At the front of the eye is the cornea.

However the sclera a tough leather-like tissue also extends around the eye. Conjunctiva - The conjunctiva is a mucus membrane that covers the surface of the eye and the inner part of the eyelids. The fluid produced in the eye.

A tough white covering called the sclera protects the eye. Anatomy of the eye. Located in the retina between the choroid and the retinal pigmented epithelium RPE layer.

Make sure that the patient understands that although he may be.
