Keratoconus causes the cornea to thin, weaken and bulge. The same word is translates as "the cone-shaped cornea." Myopia, astigmatism, glare and light sensitivity are common early symptoms disease. A as Over time, the cornea can become very thin, strong and irregular, causing severe vision loss and it was impossible to carry contact lenses.
Symptoms
Symptoms usually begin to appear when a person is in their teens or early twenties, and symptoms progress t20 for 10 years. Each eye may be affected differently. Some people eventually slows progression and the disease can be stabilized. Symptoms may include:
· Myopia
• The astigmatism
· Difficulties vision
· Glare
· Light sensitivity
· Change frequently prescribing glasses
· Href = "http://www.safelasik.org/lasik7dryeye.htm"> Eye rubbing
Dropsy
In advanced cases, a protective layer of tissue called Descemet's membrane can rupture allowing fluid to flow into the cornea, causing vision sudden blurred. This phenomenon is called dropsy. A white spot appears on the cornea and the eye may appear dull. The purpose of diminishing the Descemet layer as cured. In some patients hydrops causes scarring of the cornea flattens the cornea and in fact makes it easier for contact lens fitting.
Causes
The cause of keratoconus is unclear, but heredity seems to play a role. Research now shows a link between dysfunction of enzymes eyes and a chemical imbalance that causes thin cornea. Some think it is a secondary disease. What we know is that exposure to sunlight, rubbing eyes, chronic irritation of the eyes, and wearing contact lenses that do not fit incorrectly can cause major damage.
Treatments
Salaries and vision correction varies depending on how advanced the state of becoming. Over time, keratoconus caused the cornea to become very hard, thin and irregular, which means that as the disorder progresses steps to correct the vision and anticipation.
Glasses · and soft contacts. The use of glasses can improve vision in keratoconus very early stages, but ultimately most people will have to wear contact lenses gas permeable. Be installed correctly to avoid further damage.
Intacs ·. in plastic, placed inside the eye, can help stabilize the cornea. You can correct a certain degree of myopia, and make the shape of the cornea more regular, it can mean the possibility of using contact lenses.
• The corneal collagen cross-linking riboflavin. A new treatment with eye drops containing vitamin B2 (riboflavin) and a special light, can strengthen collagen in the eye, and may halt the progression of the disease.
"Registration of the cornea. About 20 percent of patients required corneal transplantation. In most patients given a cornea transplant good vision for at least five years.
Keratoconus and corneal thinning implies therefore LASIK and other types of refractive surgery that involves removing corneal tissue are dangerous for people with this disorder. Because there is strong evidence that the condition can be inherited and delayed diagnosis of keratoconus is fairly common, if you have a family history of illness, you should inform your eye doctor and be tested before refractive surgery.
