After a myopia she astigmatisma disease that causes deformity of the cornea and incorrect generation: keratoconus. There is no cure, but early diagnosis is the key to treatment.
In the early stages, the symptoms are similar to any common repair error. As the disease progresses, vision deteriorates, at first far away. In some individuals, the generation in one eye it is worse than the other, and there are some who develop hypersensitivity to light (photophobia). In most cases, it is a painless pathology, although when it progresses the sensation of grit or a foreign body may appear due to poor corneal lubrication.
This disease shows its first symptoms at a young age, then continues slowly until it reaches its final stage, in some cases the development of keratoconus remains at a standstill, without progress occurring. In general, the disease is seen in teenagers and young patients, around 20 years old, who go to the ophthalmologist because of progressive vision problems.
Sometimes it also shows its first symptoms at a later age and in this case the disease does not progress although, the visual acuity is better and the astigmatism is reduced. Although we do not know the exact cause, hereditary factors (sometimes there are several disease relationships), genetic factors (for example associated with Down Syndrome) and allergic factors (due to frequent eye rubbing), among others . Washing the eyes does not cause the disease, but it increases its development.
In general, people with astigmatism or myopia do not see well with glasses and must change their prescription often, may suffer from keratoconus. At least one in every 2,000 people in the world suffers from this disease.
Him keratoconus There is no cure, but there are preventive measures to delay its progression and improve vision. An example of this is the specific treatment of the elderly corneawhich has been in force for 20 years.
In the early stages of the disease, when keratoconus is presented as well myopia she astigmatism not really high, those ophthalmologist will recommend glasses to correct the visual defect. Contact lenses are also a great help. Finally, there is a corneal transplant, reserved for the most difficult cases. That is why it is recommended to visit the ophthalmologist at least once a year. As a barrier.
