H18.60
Keratoconus, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Keratoconus is an eye condition that causes the normally round cornea to thin and bulge into a cone-like shape. This change can lead to distorted vision and increased sensitivity to light. Although keratoconus can develop at any age, it most commonly begins during the teenage years and progresses into the early 30s. The condition affects the cornea, the clear, dome-shaped surface that covers the front of the eye, which plays a vital role in focusing light onto the retina. When the cornea becomes irregularly shaped, it can significantly impair vision. Early diagnosis and management are essential to slow progression and improve visual outcomes.
Causes & Symptoms
Clinical Causes: Genetic factors: Family history of keratoconus or other corneal disorders increases risk. Environmental factors: Eye rubbing due to allergies or irritation may contribute to onset or progression. Structural weakness: Abnormalities in the collagen fibers that make up the cornea can cause thinning and shape changes. Other conditions: Certain systemic diseases like Down syndrome, Ehlers-Danlos syndrome, or Marfan syndrome are associated with an increased risk.
Key Symptoms: Gradually worsening vision that may fluctuate Increased sensitivity to bright lights or glare Frequent changes in prescription glasses or contact lenses Haloes or ghosting around lights, especially at night Blurred or distorted vision Frequent eye irritation or discomfort
Diagnostic & Treatment
Diagnosis Path: Diagnosing keratoconus involves a comprehensive eye examination including tools such as corneal topography or tomography, which map the surface curvature of the cornea to identify irregularities. Additional tests like pachymetry measure corneal thickness, providing further evidence of thinning characteristic of keratoconus. An ophthalmologist may also conduct slit-lamp examinations to observe the cornea’s appearance directly, noting signs like stromal thinning or Fleischer rings. The combination of these assessments helps confirm the diagnosis and determine the disease stage.
Treatment Protocols: Management strategies aim to slow disease progression and improve vision. These may include: - **Eyeglasses or soft contact lenses** for mild cases - **Rigid gas permeable (RGP) contact lenses** that provide a smooth corneal surface for clearer vision - **Scleral lenses** which vault over the irregular cornea, offering improved comfort and clarity - **Corneal cross-linking**: A minimally invasive procedure that strengthens the corneal tissue to halt progression - **Other surgical options** such as intracorneal ring segments or corneal transplant in advanced cases Regular monitoring and tailored treatment plans are crucial for effective management of keratoconus, with ophthalmologists guiding appropriate interventions based on disease severity.
