Visual health problems
________________________________________
We use our eyes in these days more than the use of her ancestors, we are facing money cars and television for hours, read books and newspapers, and watch (movies). In spite of this extensive use of sight seems able to meet all these requirements without excessive stress.
The eye piece of engineering strange and too big to be incredible - camera has a self-adjustment was with the displaced and the reform of housing (internal). Consider this machine that is extremely sensitive to the world of a quarry padded protected, and do not require the owner of the only moderate attention in order to ensure good service and continuing for life.
Anatomical and functional structure of the eye
Radius of the eye ball about 2.5 cm, and consists of three basic layers are ordered from outside towards the inside as follows: solid Sclera and choroid and retina Choroid Retina.
Composed of solid connective tissue dark to light in all regions of the eye ball back, but changed a bit in the front becomes transparent and more Thdba The structure known as the cornea Cornea. The chorionic layer, it has a rich distinguished Balosbgp numbers of blood vessels which are penetrated by rains. The altered form of this class in the front to make up iridocyclitis Ciliary body and iris, Iris.
Iridocyclitis is a structure containing the circular ciliary glands and smooth muscles. And see the bands outstanding issued by iridocyclitis and connected to an end with the other accents or bandage lens. Lens and lens develop bilateral convexity. The iris is the colored part of the eye, and contains a hole in its claims Iris (human eye - pupil Pupil). It also includes a circular smooth muscle fibers and other X-ray or longitudinal positioning. The task of these fibers control the extent of the slit of an eye (iris) of the decline in fiber ring that restricts or capture iris, or through reduced radial and longitudinal fibers, which extends and is accompanied by this work to modify the amount of light entering the eye.
The retina, they occupy the rear two-thirds of the placental and contains light receptors known as sticks (Alnbabi) and cones. This is located to the medial axis of the eye ball front rear fiber optic nerve optic nerve leaving the eye. It claims that make up the optical disk, which is estimated optic disc diameter of about 1.5 mm. We find about 3 mm and a wild area in the above mentioned, near the front axle back to the eye ball, with the intention of great importance is the yellow stain in the center a small decline Alhverp central claims.
And fill the void located between the retina and lens gel transparent, claiming mixing glass or vitreous viterous body. The confined space between the cornea and lens from the front and the back of the iris, it is named the front compartment eye anterior chamber. The rear compartment posterior chamber of the eye, it is the narrow path confined between the iris and lens from the front and iridocyclitis in the back. Ahadjirtan and fills the front and back-mixing of water.
Eye infection and a number of organic diseases and functional in our theme we will focus on the turbulence and poor visual function of the eye.

cornea transplant A cornea transplant is a surgical procedure to replace part of your cornea with corneal tissue from a deceased donor. Your cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye's focusing power. A cornea transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. A cornea transplant, also called keratoplasty, is typically performed as an outpatient procedure. A cornea transplant is most often used to restore vision to a person who has a damaged cornea. A cornea transplant may also relieve pain or other signs and symptoms associated with diseases of the cornea. A number of conditions can be treated with a cornea transplant, including: - Thinning of the cornea
- Cornea scarring, caused by infection or injury
- Clouding of the cornea
- Swelling of the cornea
- Corneal ulcers, including those caused by infection
- Complications caused by previous eye surgery
Cornea transplant is a relatively safe procedure. Still, a cornea transplant does carry a small risk of serious complications, such as: - Eye infection
- Increased risk of clouding of the eye's lens (cataracts)
- Pressure increase within the eyeball (glaucoma)
- Problems with the stitches used to secure the donor cornea
- Rejection of the donor cornea
- Swelling of the cornea
Signs and symptoms of cornea rejection
In some cases your body's immune system may mistakenly attack the donor cornea. This is called rejection, and it may require another cornea transplant. Make an appointment with your eye doctor if you notice any signs and symptoms of rejection, such as: - Loss of vision
- Pain
- Redness
- Sensitivity to light
Rejection occurs in about 20 percent of cornea transplants. Put another way, for every 10 people receiving cornea transplants, two people can expect to experience rejection of the donor cornea. Before cornea transplant surgery, you will undergo: - A thorough eye exam. Your eye doctor looks for conditions that may cause complications after surgery.
- Measurements of your eye. Your eye doctor determines what size donor cornea you need.
- A review of all medications and supplements you're taking. You may need to stop taking certain medications or supplements before or after your cornea transplant.
- Treatment for other eye problems. Unrelated eye problems, such as infection or inflammation, may reduce your chances of successful cornea transplant, so your eye doctor will work to treat those problems before your surgery.
Finding a donor cornea
Corneas used in cornea transplants come from deceased donors. Unlike with other organs, such as livers and kidneys, people needing cornea transplants generally don't have to endure long waits. That's because nearly all people can donate their corneas after they die, so more corneas are available for transplant compared with other organs. Most people who receive a cornea transplant will have their vision at least partially restored. But what you can expect after your cornea transplant depends on the reason for your surgery and your health conditions. Your risk of complications and cornea rejection continues for years after your cornea transplant. For this reason, expect to see your eye doctor annually. Cornea rejection can often be managed with medications. Vision correction after surgery
Your vision may initially be worse than before your surgery as your eye adjusts to the new cornea. It may take several months for your vision to improve. Once the outer layer of your cornea has healed — several weeks to several months after surgery — your eye doctor will work to make adjustments that can improve your vision, such as: - Correcting unevenness in your cornea (astigmatism). The stitches that hold the donor cornea in place on your eye may cause dips and bumps in your cornea, making your vision blurry in spots. Your doctor may correct some of this by releasing some stitches and tightening others.
- Correcting vision problems. Refractive errors, such as nearsightedness and farsightedness, can be corrected with glasses, contact lenses or, in some cases, laser eye surgery
