Keratoconus - Neonatal Disorders

Introduction to Keratoconus

Keratoconus is a progressive eye disease where the normally round cornea thins and begins to bulge into a cone-like shape. This abnormal shape deflects light as it enters the eye on its way to the retina, causing distorted vision. While keratoconus is more commonly diagnosed in teenagers and young adults, it can also be detected in pediatric patients.

Signs and Symptoms in Children

In pediatric patients, the signs and symptoms of keratoconus can vary but often include:
Blurred vision
Frequent changes in prescription glasses
Astigmatism that progressively worsens
Sensitivity to light and glare
Difficulty seeing at night

Causes and Risk Factors

The exact cause of keratoconus is not well understood, but several risk factors have been identified, including:
Genetic factors: A family history of keratoconus can increase the risk.
Frequent eye rubbing
Underlying conditions such as atopic diseases (e.g., eczema, asthma) and connective tissue disorders

Diagnosis

Diagnosing keratoconus in children involves several steps:
Comprehensive eye exam to assess visual acuity and refraction.
Corneal topography to map the surface curvature of the cornea.
Pachymetry to measure corneal thickness.
Slit-lamp examination to inspect the cornea under high magnification.

Treatment Options

Treatment for keratoconus in pediatric patients depends on the severity of the condition:
Glasses or soft contact lenses for early or mild cases.
Rigid gas permeable (RGP) lenses for more advanced cases to provide clearer vision.
Corneal cross-linking (CXL) to strengthen corneal tissue and halt progression. This is particularly important in younger patients to prevent severe vision impairment.
Intacs (corneal implants) to reshape the cornea.
Corneal transplant for severe cases where other treatments are ineffective.

Prognosis and Follow-Up

Early detection and treatment of keratoconus in children are crucial for a better prognosis. Regular follow-up appointments with an ophthalmologist are essential to monitor the progression of the disease and adjust treatment plans as necessary.

Conclusion

Keratoconus is a significant eye condition that can affect pediatric patients, potentially leading to severe vision problems if not diagnosed and treated early. Awareness of the symptoms and risk factors, combined with prompt medical intervention, can help manage and mitigate the impact of this condition on a child's vision and overall quality of life.
