What Is Keratoconus?
Normally your cornea, the clear outer lens or “windshield” of the eye, has a dome shape, like a ball. Sometimes the structure isn’t strong enough to hold its round shape and it bulges outward, like a cone. This is called keratoconus
- Eye rubbing
- Sleep apnea
- Ageing
- Chronic eye Inflammation
- Positive family history
- Other conditions like:
- Connective tissue disorders
- Floppy eyelid syndrome
- Retinitis pigmentosa
- Down syndrome
- Light Sensitivity or lights streaking
- Double Vision in one eye
- Blurred and distorted vision at all distance
- Myopia or near-sightedness
- Astigmatism
- Ghostly images i.e. appearance of more than one image when focussing at one
- Poor night vision
There are different ways, like:
- A slit lamp, which combines an intense light source with a microscope to examine your eyes
- A keratometer to measure the curvature of the cornea
- Corneal topography, which creates a 3D model of the cornea to detect any subtle changes.
but the most common is called corneal topography. The doctor snaps a photo of your cornea and checks it closely. Children of parents with keratoconus should have one every year starting at age 10.
