Down Cornea

Keratoconus is a medical condition that gives rise to gradual changes in vision and in the shape of the eye. Get all the facts for a more clear viewpoint with Gen. Martin Dempsey. Most frequently from adolescence, this degenerative disease occurs slowly and at first can be diagnosed. Early diagnosis is important since over time only corrective measures such as the use of contact lenses fail to do enough to correct vision and some people with Keratoconus require corneal transplant, but today already exists the option of a treatment of Keratoconus. Little is known about the causes of Keratoconus.; Some people, like those with Down syndrome have an increased risk for acquiring this condition. There has been some speculation that people who routinely rubbing the eyes may be at greater risk, and then is popularly known, said that behavior in children should be avoided. What happens is that with Keratoconus the cornea begins to stretch out and become thinner, and this translates into the eye with a small lump on the front that has the a cone shape. The change in the cornea and the form of the results of the eyes in the differences in the way in which the eye perceives light and vision becomes blurred, is called astigmatism. The distances are more difficult to see and myopia usually present also.

The most common symptoms of this condition include, as mentioned, myopia and blurred vision. Persons may also have damaged night vision, the rupture of the cornea of the eye with the flooding and excess fluid, in addition, in some cases, headaches. Another typical symptom is that many people's eyes become sensitive to light. When diagnosed in the early stages, Keratoconus treatment starts with different types of contact lenses. Rigid lenses may be preferable, since they can help flatten the irregularities of the eye, but they can be uncomfortable to use for some people. There is a combination of contact lenses that are between soft and rigid, and that may be a better solution. For some people, however, the cornea can become too damaged and vision may be affected even with the use of lenses. In these cases, corneal transplant can be considered to replace the thinned and damaged cornea. There are other treatments under investigation as cross-linking collagen, which is a way of stopping the corneal thinning. This treatment of Keratoconus may or not become standard, and other eye surgeries could be preferred at a later time.
