Through the Eyes of Keratoconus: Understanding Corneal Challenges

Keratoconus is a relatively rare eye disease, affecting one in 1000 people. Despite causing serious vision distortion, it does not lead to blindness. This condition manifests with a bulging or dome-shaped cornea, transforming its usual structure into a cone-like shape.

The Role of the Cornea:

Situated in the anterior part of the eye, the cornea is a thin layer responsible for focusing light on the retina. In a normal scenario, the retina transmits electrical signals to the visual cortex in the brain through the optic nerve. However, when afflicted by keratoconus, the altered cornea disrupts this process, resulting in blurred vision.

Onset and Progression of Symptoms:

Typically emerging during the teenage years, keratoconus progresses slowly over two decades. Symptoms begin with mild vision distortion and blurriness, often dismissed initially. Sensitivity to light also becomes prominent. As the cornea continues to bulge, eyesight deteriorates, accompanied by swelling, irregular shape, cracks, and scar tissue formation.

Keratoconus Diagnosis and Management:

Early diagnosis is crucial, and regular eye checkups are recommended. Collagen cross-linking is a suggested intervention to slow down progression. Expert consultation is imperative, considering the unique nature of keratoconus. Various tests, including slit lamp, corneal pachymetry, corneal topography, and retinal examination, aid in accurate diagnosis.

Treatment Approaches:

During the initial stages, contact lenses or eyeglasses may be prescribed. Collagen cross-linking is typically performed before the age of 25, while rigid gas permeable contact lenses are recommended for curved corneas. Kerarings, applied to reduce bulging, can be implanted alongside cross-linking. In extreme cases, corneal transplantation serves as a last resort.

Managing Keratoconus for Clear Vision:

Understanding the causes, recognizing symptoms, and seeking timely intervention through appropriate treatments are pivotal in managing keratoconus. Regular eye care, expert consultation, and adherence to prescribed treatments can significantly improve the quality of life for individuals with this condition.
