H18.623
Keratoconus, unstable, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Keratoconus is a progressive eye condition in which the normally round, dome-shaped cornea thins and begins to bulge outward into a cone-like shape. When this condition is considered unstable and affects both eyes, it can significantly impact vision and quality of life. ICD-10 code H18.623 specifically describes bilateral, unstable keratoconus, highlighting its influence on both eyes and the ongoing nature of the condition.
Causes & Symptoms
Clinical Causes: Genetic predisposition, often running in families Chronic eye rubbing or trauma Certain connective tissue disorders such as Ehlers-Danlos syndrome or Marfan syndrome Inflammation of the eye (keratitis)
Key Symptoms: Blurry or distorted vision Sensitivity to light and glare Frequent changes in eyeglass or contact lens prescriptions Images appearing distorted or stretched Eye strain or discomfort Haloes or glare around lights, especially at night
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive eye examination. An eye care professional may use specialized imaging techniques such as corneal topography or tomography to assess the shape and thickness of the cornea. These tests are essential in identifying irregularities characteristic of keratoconus and monitoring its progression, especially in cases classified as unstable.
Treatment Protocols: While keratoconus cannot be cured, several management options can help improve vision and slow disease progression: - **Eyeglasses and contact lenses:** Mild cases may be corrected with glasses, but as the condition worsens, various contact lens types (rigid gas-permeable, scleral lenses) are often used. - **Corneal cross-linking:** A minimally invasive procedure that strengthens corneal tissue and can halt or slow progression, especially useful in unstable keratoconus. - **Intacs or corneal implants:** Small devices surgically inserted into the cornea to flatten its shape and improve vision. - **Corneal transplant:** In advanced cases where other treatments are ineffective, a transplant may be necessary to replace the damaged corneal tissue. Regular monitoring and personalized treatment planning are crucial in managing bilateral, unstable keratoconus effectively.
