H18.429
Band keratopathy, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Band keratopathy is a condition characterized by the buildup of calcium deposits in the superficial layers of the cornea, the transparent front part of the eye. When these calcium deposits form a band-shaped opacity across the cornea, it can affect vision and eye comfort. The specific code H18.429 identifies cases where this condition affects an unspecified eye, indicating that the exact eye involved has not been detailed.
Causes & Symptoms
Clinical Causes: Chronic inflammation or injury to the eye Chronic eye conditions such as uveitis or scleritis Elevated levels of calcium in the blood (hypercalcemia) Kidney disease leading to calcium and phosphate imbalance Long-term use of certain eye medications or topical steroids Aging process, which may contribute to calcium deposits Previous eye surgeries or trauma
Key Symptoms: Blurred or decreased vision Grayish or whitish band across the cornea Irritation or discomfort in the eye Sensitivity to light Feeling of a foreign body in the eye Redness or swelling around the eye (less common)
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves an eye examination using slit-lamp microscopy, which allows the eye care professional to observe calcium deposits in the cornea. The doctor may also review the patient's medical history for underlying conditions like hypercalcemia or kidney disease. Additional tests, such as blood tests to check calcium levels, may be ordered to identify underlying causes.
Treatment Protocols: Treatment options depend on the severity and underlying cause of band keratopathy. Common approaches include: - Removing calcium deposits through a surgical procedure called chelation, where a chelating agent like EDTA is used to dissolve calcium. - Managing underlying conditions such as hypercalcemia or kidney disease. - Using custom contact lenses or glasses to improve vision if necessary. - In some cases, phototherapeutic keratectomy (PTK), a laser procedure, may be performed to eliminate superficial deposits. - Regular follow-up is important to monitor and prevent recurrence.
