What is cornea Conus?

In keratoconus, your cornea thins and gradually bulges outward into a cone shape. This can cause blurry, distorted vision. Keratoconus (ker-uh-toe-KOH-nus) occurs when your cornea — the clear, dome-shaped front surface of your eye — thins and gradually bulges outward into a cone shape.

What causes keratoconus eye disease?

What causes keratoconus? Although keratoconus has been studied for decades, it remains poorly understood. The definitive cause of keratoconus is unknown, though it is believed that the predisposition to develop the disease is present at birth. A common finding in keratoconus is the loss of collagen in the cornea.

What is it called when your eyes are oval?

Astigmatism occurs when either the front surface of the eye (cornea) or the lens inside the eye has mismatched curves. Instead of having one curve like a round ball, the surface is egg-shaped. This causes blurred vision at all distances.

Can a 5 year old have keratoconus?

Is keratoconus genetic?

In most cases, keratoconus is not inherited and occurs in individuals with no family history of the disorder. The condition can also occur in families.
