What do you need to know?
- Corneal cone is a condition in which the cornea becomes thinner and deforms, which can lead to visual disturbances.
- Objawy stożka rogówki to pogorszenie pola widzenia mimo korekcji okularowej, zaczerwienienie, pieczenie, swędzenie oraz podwójne widzenie.
- A corneal cone rarely leads to complete loss of vision, but it can make daily functioning much more difficult.
- If symptoms are noticed, it is important to see an ophthalmologist as soon as possible for appropriate treatment and to control the progression of the disease.
Corneal cone - what is this condition?
The cornea is characterised by its ability to focus light beams and, together with the lens, is responsible for collecting light rays and then „projecting” them onto the retina, where the image we see is formed. Corneal cone, on the other hand, occurs when the cornea becomes too thin and deforms.
Allergies, which contribute to frequent rubbing of pollen-irritated eyes, may be the cause of this condition. It is also assumed that corneal cone may be hereditary. It also appears in patients with genetic conditions, such as Down syndrome.
Do rozwoju stożka rogówki mogą przyczynić się też często występujące infekcje i choroby oczu, takie jak: zapalenie spojówek.
Can a corneal cone lead to vision loss?
Such cases are very rare. A corneal cone often leads to severe vision problems and impedes daily functioning, but it is not common for patients to lose their sight because of it.
How to characterise the symptoms of corneal cone?
Symptoms especially at first are not easy to diagnose. Patients wearing corrective spectacles notice a significant deterioration of the visual field over time, and despite changing the power of the correction, the visual disturbance continues to progress.
So often, before a corneal cone is diagnosed, the ophthalmologist will increase the power of the lenses for some time in order to increase visual acuity.
Among the symptoms to look out for are:
- Redness.
- A „burning” sensation in the eye
- Itchy eyes.
- Double vision.
It is then worth checking for symptoms in each eye. A corneal cone rarely occurs symmetrically in both eyes.
On the other hand, it may happen that when looking with both eyes we see quite well, but when closing one eye we notice a definite deterioration and very strong symptoms indicating poor vision, which may turn out to be a corneal cone disorder.
It may also mean that the disease is developing faster in one eye than the other. Remember that you should make an appointment to see your eye doctor as soon as possible if this happens.
