Keratoconus Affects on the Cornea
Understanding How Keratoconus Affects the Cornea
Among the many components of the eye, the cornea is a vital structure responsible for focusing light onto the retina, enabling us to see clearly. However, certain conditions can affect the cornea, leading to vision problems and discomfort. One such condition is keratoconus, a progressive eye disorder that affects the cornea’s shape and structure. In this blog post, we will explore how keratoconus affects the cornea and its impact on vision.
Understanding Keratoconus
Keratoconus is a condition characterized by the thinning and bulging of the cornea, resulting in a cone-shaped protrusion. This abnormal shape can cause light to be refracted unevenly, leading to distorted or blurred vision. While the exact cause of keratoconus is unknown, it is believed to be a combination of genetic and environmental factors.
How Keratoconus Affects the Cornea
- Thinning of the Cornea: In keratoconus, the cornea gradually thins and weakens, causing it to bulge outward. This thinning can result in a loss of corneal stability and shape irregularities, leading to distorted vision.
- Irregular Astigmatism: As the cornea becomes more distorted, it can create irregular astigmatism, where light entering the eye is not evenly focused. This can cause blurred or double vision, especially at night or in low-light conditions.
- Corneal Scarring: In some cases, keratoconus can lead to corneal scarring, further compromising vision. Corneal scarring can occur due to the stretching and thinning of the cornea, which can cause tears in the corneal tissue.
- Increased Sensitivity to Light: Keratoconus can also lead to increased sensitivity to light (photophobia) due to the irregular shape of the cornea. This can cause discomfort and difficulty with activities such as driving at night or working on a computer for extended periods.
- Decreased Visual Acuity: As keratoconus progresses, visual acuity can decline, making it difficult to see clearly even with corrective lenses. This can significantly impact daily activities and quality of life.
