Keratoconus is the pathological deformation of the cornea that has non-inflammatory nature. Under the influence of structural changes, the cornea is getting thinner and gains a cone shape instead of spherical, as it is supposed to have naturally. The disease occurs because the main substance of the cornea loses its natural mechanic abilities. Its structural fibers lose their strength. The pressure inside the eyes makes the cornea protrude. Usually the disease develops on both eyes.
As a rule, the keratoconus develops in teenagers, but sometimes it happens with the young people too, mostly in the age under 30. It takes time for the cornea to change its shape. Usually it happens during the period of several years. However, sometimes the process can go faster.
The reasons of the keratoconus appearance are not exactly determined yet. The scientists mark several factors that may provoke the diseases development. These are bad ecology, the dysfunction of endocrine system and the eye traumas. The genetic issues are also a powerful risk factor that is why people who have a relative with keratoconus should be aware. They are recommended to undergo the eye diagnostics regularly. The disease is being diagnosed much oftener during the last years. On the one hand, it can be explained by the improvement of diagnostic technologies, on the other hand – the worsening of the ecology.
The cone shape of the cornea does not allow ray light reflect the way they should that is why the vision sharpness drops significantly. The person sees distorted shapes and broken lines, like in cases with astigmatism and myopia. The progressing keratoconus brings difficulties with the proper optical correction. Without proper diagnostics and timely treatment keratoconus may lead to the full loss of vision. The modern computer technologies allow doing this on the earliest stage of disease and give the full information for the doctor to appoint the individual treatment.
