Keratoconus refers to a specific eye disorder that impacts the shape of the cornea, which is a clear, dome-shaped surface on the front of the eye. According to our eye care professionals at Progressive Eyecare & Eyewear in Indianapolis and Fishers, keratoconus is a progressive eye disorder that distorts the cornea, potentially leading to vision issues.
Keratoconus typically begins during the teenage years or early twenties and progresses gradually. The exact cause of this progressive eye condition is not fully understood, but environmental and genetic factors are likely contributors. It is more common in certain populations and may affect one or both eyes.
Keratoconus Causes
This eye disorder involves corneal thinning and weakening, which distorts the typical shape of the cornea, making it irregular and cone-shaped rather than round. Potential vision issues caused by keratoconus include the following:
1. Astigmatism: Irregular astigmatism, which causes distorted and blurred vision, occurs when the cornea's surface is curved differently in different parts, resulting in varying curvatures.
2. Myopia or Far-Hyperopia: Nearsightedness, or myopia, happens when the cornea bulges and steepens, making it challenging to see objects at a distance. Conversely, hyperopia or farsightedness refers to the inability to see close-up objects clearly.
3. Irregular Vision: Those with keratoconus may experience fluctuating vision distortions, which may include:
- Double Vision: Multiple images of the same object appear, making it difficult to focus.
- Ghosting: Several faint images potentially overlap, making it challenging to focus clearly on one object.
- Halos: Keratoconus has the potential to distort the shape of the cornea, causing light to scatter and resulting in halos around objects.
4. Light Sensitivity: Keratoconus causes those afflicted to be more light-sensitive, particularly in response to oncoming traffic's headlights or other bright glaring lights. This light sensitivity can reduce one's vision quality, making it particularly difficult to drive at night.
5. Reduced Sensitivity to Contrast: Individuals with this condition have a reduced ability to distinguish between objects with similar brightness or color. The result is that it is challenging to see details.
Diagnosing Keratoconus
The diagnosis involves a comprehensive eye exam, including mapping to determine corneal thinning. Early detection is essential because this condition can, depending on its severity, be managed with various treatments:
- Mild cases may be corrected with eyeglasses or contact lenses.
- Advanced cases may require specialized contact lenses.
- Severe cases where vision is significantly impaired may require surgery.
