Band Keratopathy: Symptoms, Causes, Treatment

What are the symptoms of band keratopathy?

Band keratopathy, also known as calcific band keratopathy or calcareous degeneration, is a condition characterized by the formation of calcium deposits in the cornea, which is the clear, dome-shaped surface that covers the front of the eye. Symptoms of band keratopathy can vary depending on the extent of the calcium deposits and whether they are causing irritation or vision problems. Common symptoms may include:

1. Blurred vision: Calcium deposits on the cornea can cause vision to become blurry or distorted.
2. Eye irritation: The presence of calcium deposits on the cornea can cause irritation, redness, and a gritty sensation in the eye.
3. Sensitivity to light: Some people with band keratopathy may experience increased sensitivity to light (photophobia).
4. Foreign body sensation: The presence of calcium deposits on the cornea can make it feel like there is a foreign body in the eye.
5. Decreased vision: In severe cases, band keratopathy can lead to a significant decrease in vision.

It’s important to note that band keratopathy may not always cause symptoms, especially in the early stages when the calcium deposits are small. However, if you experience any changes in vision or eye discomfort, it’s important to see an eye care professional for a comprehensive eye examination.

What are the causes of band keratopathy?

Band keratopathy is caused by the deposition of calcium salts in the cornea, which is the clear, dome-shaped surface that covers the front of the eye. The exact cause of this condition is not fully understood, but several factors may contribute to the development of band keratopathy, including:

1. Chronic eye inflammation: Conditions that cause chronic inflammation of the eye, such as uveitis or dry eye syndrome, can lead to the formation of calcium deposits in the cornea.
2. Long-term use of certain medications: The long-term use of medications such as corticosteroids or diuretics can increase the risk of developing band keratopathy.
3. Systemic conditions: Systemic conditions such as hypercalcemia (elevated levels of calcium in the blood), hyperparathyroidism (overactivity of the parathyroid glands), or kidney disease can increase the deposition of calcium in the cornea.
4. Degenerative conditions: Degenerative conditions of the eye, such as age-related macular degeneration or retinitis pigmentosa, may be associated with band keratopathy.
5. Previous eye surgery or trauma: Previous eye surgery or trauma to the eye can increase the risk of developing calcium deposits in the cornea.
6. Contact lens wear: Prolonged or improper use of contact lenses can lead to corneal irritation and inflammation, which may contribute to the development of band keratopathy.

It’s important to note that band keratopathy is a rare condition and may not always have a clear cause. If you are experiencing symptoms of band keratopathy, it’s important to see an eye care professional for a comprehensive eye examination to determine the underlying cause and appropriate treatment.

What is the treatment for band keratopathy?

The treatment for band keratopathy, which is the deposition of calcium salts in the cornea, depends on the severity of the condition and whether it is causing symptoms. Treatment options may include:

1. Conservative management: In mild cases where the calcium deposits are not causing significant vision problems or discomfort, no treatment may be necessary. Regular monitoring by an eye care professional is recommended.
2. Chelation therapy: Chelation therapy involves the use of chelating agents, such as EDTA (ethylene diamine tetra-acetic acid), to dissolve the calcium deposits in the cornea. This treatment is typically used for more severe cases of band keratopathy.
3. Surgical removal: In some cases, surgical removal of the calcium deposits may be necessary, especially if they are causing significant vision problems or discomfort. This procedure is known as keratectomy and is usually performed under local anesthesia.
4. Treatment of underlying conditions: If band keratopathy is caused by an underlying systemic condition, such as hypercalcemia or kidney disease, treatment of the underlying condition may help prevent the recurrence of calcium deposits in the cornea.
5. Corneal transplantation: In rare cases where band keratopathy is causing significant vision loss and other treatments have been ineffective, a corneal transplant may be considered. During a corneal transplant, the damaged cornea is replaced with a healthy donor cornea.

It’s important to see an eye care professional for a comprehensive eye examination if you suspect you have band keratopathy. They can determine the severity of your condition and recommend the most appropriate treatment for your specific situation.
