Eye condition and eye disease- Know the difference

CB011723Do you find yourself confused hearing to these two terms - EYE CONDITION and EYE DISEASE? We can assure you that you wont need to go any further and just scroll down. Leave your comments after reading through the article, if it helps you to find a respite from your age old confusion.

We would be very specific in our approach in order to make things simpler for your understanding. Now just follow the conversation between the doctor and the patient who is suffering from glaucoma:

Patient : Doc, what is the disease all about which is causing me so much paiin in

my eye?

Doctor : It is a typical type of disease known as glaucoma. This eye condition

develops due to increase in pressure inside your eye due to failure in

drainage system of eye. The watery fluid produced in your eye is failing to

find a way to escape your eye and thus it is getting accumulated there.

This eye condition is leading to enhance pressure to the eye ball and

pushing it outside which is causing the pain.

Patient : So what is the cure for this disease? how can I get back my normal eye

eye condition?

Doctor: I will have to undergo an operation to cure the disease and revive the

normal eye condition.

We hope after careful reading of the above conversation you can find that normal condition of any organ is the normal metabolic functioning of eye. While any abnormality or irregularity of an organ's condition leads to a disease.

Thus there is a very thin "line of control" between the meaning of eye condition and eye disease. While the former causes the malfunctioning of the eye and the later is the outcome of it.

For example, glaucoma is the disease and the increasing internal eye pressure is the impaired eye condition leading to glaucoma. Let us list some of the major eye conditions:

Myopia - (nearsightedness)
People with Myopic vision usually have eyeballs that are too large for their lens and cornea to focus light properly on their retina. Eyeglasses and contact lenses can usually correct this problem.
Hyperopia - (farsightedness)
Hyperopia vision is caused by the eyeball being too small for the lens and cornea to focus light properly on the retina. Eyeglasses and contact lenses can usually correct this problem.
Presbyopia - (aging eyes)
As people age, they often begin to have difficulty focusing their eyes for reading or close work. It is usually corrected with reading glasses. Some people may need bifocal of trifocal lenses.
Astigmatism - (distorted vision)
People with Astigmatism have irregularly shaped corneas. It is usually corrected with eyeglasses or contact lenses.

Apart from these there are several eye conditions which lead to cause diseases such as :

Cataracts
There are over 1 million Cataract operations performed annually in the USA. Cataract surgery is an outpatient procedure with a very high success rate. Due to the lack of modern medical technology in the developing world, it is also the world's leading cause of blindness. Over 16 million people are blind from cataracts.
Age-Related Macular Degeneration - (AMD)
This is a degenerative disease of the macula; the macula is the part of the retina responsible for central vision. There is no way yet of repairing the vision that has been lost, but if detected early laser surgery can help slow the progression of the disease. (AMD) is the leading cause of vision loss in people over age 65. Eight million people are legally blind from macular degeneration worldwide and as the population ages this number is expected to grow.
Glaucoma
This disease increases the fluid pressure inside the eye, leading to loss of side vision and eventually total blindness. The increased pressure destroys the optic nerve. With early detection, it can be kept under control with pressure reducing eye drops and surgery. Chances of developing it increase with age. There are over five million people blind from glaucoma worldwide.
Diabetic Retinopathy
This complication of diabetes is a leading cause of blindness among middle-aged Americans. The longer a person has had diabetes the more apt they are to develop diabetic retinopathy. Laser surgery can slow the progression of this disease along with management of blood glucose levels. There are 2.4 million people blind from retinopathy worldwide.
Retinitis Pigmentosa - (RP)
This rare inherited degenerative disease slowly destroys the retina. Signs of (RP) first show up in early childhood. The side vision is lost first. The Disease progresses over many years leaving the person with only a small portion of their central vision. There is on cure for (RP) yet. There are 1.6 million people blind from (RP) worldwide.
Eye Injuries
Over 1 million people are blind worldwide from eye injuries. 90% of injuries can be avoided by using proper eye protection. If you are reading this page now because you or a loved one has an eye injury, turn your computer off and get medical attention. Any eye injury is a medical emergency.
Optic Nerve Hypoplasia
With this birth defect the optic nerve that connects the eye to the brain has not developed properly, it is underdeveloped. This happens before birth leaving the child with mild to sever vision loss. In most cases, there is no known cause.
Retinopathy of Prematurity - (ROP)
This is an eye disease of premature babies. Soon after birth, abnormal blood vessels start to grow on the retina eventually destroying it. No one is quite sure what causes this disease, but premature birth and low birth weight are thought to be the main causes. With modern medical procedures, only 400 babies a year go blind from this condition. In the 1950's the number of babies blind from (ROP) reached epidemic proportions.
Neurological Visual Impairment (NVI)
Children with (NVI) have normal eyes, but a part of the brain responsible for seeing is damaged. It can be caused from a lack of oxygen before, during, and after birth. Diseases like meningitis or traumatic brain injury can also cause it. Many of the children with (NVI) are multihandicapped. Vision loss can be temporary or last a lifetime.
Ocular Albinism
With this inherited birth defect, people have no pigment or reduced pigment in their eyes, skin and hair. This pigment called melanin is needed for the full development of the retina. Children with this condition have mild to sever vision loss and are very light sensitive.
Coloboma
Coloboma is a Greek word, which means mutilation. People with Coloboma are missing a portion of the structure of the eye. The human eye develops between the fourth and fifteenth week of pregnancy. As the eye starts to develop, a gap opens on the underside of each eye bud. This gap provides a way for the developing eye to be nourished. This gap, called the optic fissure, has to close before the eye is fully developed. Coloboma is the incomplete closer of the optic fissure. Gaps can occur in the eyelid, iris, ciliary body, lens, retina, macula, choroid and optic disc. It can cause from mild to sever vision loss. Coloboma occurs in about 1 in 10,000 births.
Preventable Vision Loss
Over 90% of the world's blind people live in developing countries. Many diseases can be prevented with education in basic hygiene, proper nutrition and medical care. Conditions unheard of in the modern world like: Trachoma, Onchocerciasis (river blindness) and nutritional blindness (vitamin A deficiency), are the leading causes of vision loss in these countries.

Hope we succeeded in our attempt to make you understand the difference. So next time round if anyone asks "how is your eye disease?" contradict him and say "my eye condition is quite OK now."
