ü  What is a cone cornea and how can it be treated?

The cone or keratoconus, also known as the keratoconus, occurs when your cornea (the transparent, domed outer surface of your eye) becomes thin and gradually becomes a conical state, one of the most common diseases in the cornea, which can cause vision problems if not followed up and treated on time.

The conical cornea causes blurred vision and may cause light sensitivity and shine in vision. The cone cornea usually affects both eyes, although often one eye is affected by this fear more than the other. It often affects people between the 10 and 25 years of old. It can gradually last up to 10 years.

In the early stages of the cone cornea, you may be able to fix vision problems with glasses or soft contact lenses. Later, you may have to use inflexible and permeable contact lenses or other types of lenses such as crucifix lenses. If the disease goes up to an advanced level, you may need a corneal transplant.

A new treatment called corneal crosslink collagen may help slowly progress or stop the cone’s cornea, which is likely to prevent the need for future corneal transplantation. This treatment may be offered in addition to the vision correction options mentioned above.

  • Conical corneal symptoms

Signs and symptoms of the cone cornea may change as the disease progresses. These symptoms include:

  • Blurred vision
  • Reduce sensitivity to light and shine, which can cause problems during driving at night.
  • Requires frequent changes in eyeglasses score
  • Sudden destruction of vision or blurred vision
  • One of the symptoms of conical cornea is blurred vision, decreased sensitivity to light .

If your eyesight deteriorates quickly and is likely to develop with a curvature abnormality, see your ophthalmologist who may also notice the symptoms of the cone cornea at the time of the examination.

  • What are the causes of conical cornea?

No one knows the causes of the cone cornea, although genetic and environmental factors are believed to be associated with this issue. About 1 in 10 people with cone corneas have parents with these conditions.

  • Risk Factors

These factors can increase your chances of developing a cone cornea:

  • Have a family history of conical corneal disease
  • Severe eye rubbing
  • Having diseases such as retinal inflammation, Down syndrome, Ehmers-Datlos syndrome, hay fever and asthma.
  • Conical corneal complications

In some situations, your cornea may swell quickly, causing sudden loss of vision and corneal damage. It is caused by conditions in which cells break down inside the cornea, transferring fluid into the cornea (hydrops). Swelling usually subsides on its own, but damage and scarring may affect your eyesight. An advanced cone cornea may also cause damage to your cornea, especially where the bulging part is more severe. Damaged cornea causes worsening vision problems and may require corneal transplant surgery.

  • Methods of detection of conical cornea

To diagnose a cone or corneal hump, your ophthalmologist (ophthalmologist or optic meter) will review your medical and family history and perform an eye exam. He may take other tests to determine more details about the shape of your cornea. Tests used to detect conical corneas include:

  • Ocular Refration
  • It shines light on the surface of your eye and uses a low power microscope to see your eyes.
  • Keratometry
  • Computer corneal imaging
  • Ways to treat conical corneas

Treatment of the cone cornea depends on the severity of your illness and the speed of its progression.  Generally, there are two approaches to treating the cone cornea: slowing the progression of the disease and improving vision.

If your cone cornea is progressing, corneal crosslink collagen may slow or stop the progression of the disease, depending on the severity of the cone cornea, and the partial to moderate cone cornea can be improved with glasses or contact lenses, especially if the cornea is stable relative to time or collagen binding, it may be a long-term treatment. In some people with cone corneas, the cornea is damaged by disease progression, or contact lenses may be difficult to use.

  • Soft glasses or contact lenses
  • Hard contact lenses
  • Pigback Lenses
  • Hybrid lenses
  • Crusal lenses
  • Collagen cross-link cornea
  • Corneal transplantation

Finally, we recommend that you take eye diseases seriously and consult an ophthalmologist as soon as possible if you feel any problems with your eyesight.
