H18.612
Keratoconus, stable, left eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Keratoconus is a progressive eye condition where the cornea, the clear outer layer of the eye, becomes thin and cone-shaped. When this condition remains unchanged over time, it is described as stable keratoconus. Specifically, the code H18.612 refers to keratoconus affecting the left eye that is currently stable, meaning there has been no recent progression or worsening of the condition. Recognizing and managing stable keratoconus is important for maintaining good vision and preventing future complications.
Causes & Symptoms
Clinical Causes: Genetic factors, often running in families Chronic eye rubbing or inflammation Structural weaknesses in the corneal tissue Environmental factors such as prolonged exposure to UV light Certain connective tissue disorders like Ehlers-Danlos syndrome or Marfan syndrome
Key Symptoms: Mild to moderate blurred vision Sensitivity to light and glare Frequent changes in corrective lens prescriptions Distorted vision, especially with distance objects Hightened perception of halos around lights
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves comprehensive eye examinations, including corneal topography or tomography to map the corneal surface, which helps identify the cone-shaped protrusion. An ophthalmologist may also perform slit-lamp examinations and assess visual acuity. Since the condition is described as stable, repeated evaluations over time reveal no significant change in the corneal shape or vision, confirming the stable status.
Treatment Protocols: Corrective lenses: glasses or soft contact lenses to improve vision Specialized contact lenses: scleral or rigid gas-permeable lenses that provide a smooth optical surface Cross-linking procedures: To strengthen the corneal tissue and potentially halt progression if needed Regular monitoring: Periodic eye exams to track any changes in the cornea's shape or vision Surgery: In rare cases, procedures such as intracorneal ring segments or corneal transplant may be considered if vision becomes significantly impaired
