H18.423
Band keratopathy, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Band keratopathy is an eye condition characterized by the formation of calcium deposits in the superficial layers of the cornea, specifically in Bowman's membrane. When it affects both eyes, it is referred to as bilateral band keratopathy. This condition can cause visual disturbances and discomfort, impacting a person's quality of life.
Causes & Symptoms
Clinical Causes: Chronic ocular inflammation Hypercalcemia or abnormal calcium metabolism History of ocular injuries or surgeries Long-term use of certain eye medications Degenerative conditions such as gout or other metabolic disorders Age-related changes in the cornea
Key Symptoms: Blurred or decreased vision Grittiness or foreign body sensation in the eyes Sensitivity to light (photophobia) Appearance of a grayish, band-shaped opacity across the cornea Possible eye redness or irritation
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive eye exam, including slit-lamp examination to observe calcium deposits within the cornea. Additional tests such as blood work may be recommended to identify underlying metabolic issues. Corneal topography and imaging can help assess the extent of calcium buildup and its impact on corneal clarity.
Treatment Protocols: Treatment options depend on the severity of the condition. Mild cases may only require regular monitoring. More advanced cases often necessitate procedures such as superficial keratectomy or laser treatments to remove calcium deposits. Managing underlying causes, such as correcting calcium imbalance, may also be part of the treatment plan. In some instances, eye lubricants or medications are used to relieve symptoms.
