What is Eye Calcification?

Eye calcification refers to the accumulation of calcium deposits in various parts of the eye, primarily the conjunctiva and cornea. These deposits may be superficial or embedded within deeper layers, leading to discomfort, impaired vision, and sometimes permanent damage if untreated. Though relatively rare, this condition often signifies an underlying systemic or ocular imbalance, necessitating expert diagnosis and management.

Causes of Eye Calcification

Understanding the root causes is critical to both treatment and prevention. The most common causes include:

Systemic Conditions

• Hypercalcemia – Elevated calcium levels in the bloodstream due to parathyroid gland dysfunction, chronic kidney disease, or malignancy.

• Hyperphosphatemia – Abnormal phosphate levels that encourage calcium-phosphate salt deposition.

• Vitamin D toxicity – Excessive vitamin D raises calcium absorption, promoting tissue calcification.

Ocular Conditions

• Chronic eye inflammation – Conditions like chronic conjunctivitis or keratitis may lead to localized calcium deposits.

• Eye trauma or post-surgical effects – Injuries or surgical scars can cause abnormal tissue healing and calcium accumulation.

• Chemical exposure or irritants – Long-term use of certain phosphate-containing eye drops has been linked to corneal calcification.

Environmental and Lifestyle Factors

• Overuse of calcium/vitamin D supplements

• Prolonged exposure to dry environments

• Use of preservative-containing topical eye medications

Symptoms of Eye Calcification

Early Signs

• Persistent eye irritation or a gritty sensation

• Redness and mild inflammation

• Dryness or excessive tearing

Progressive Symptoms

• Blurry vision or light sensitivity

• Appearance of white or greyish spots on the cornea

• Sensation of a foreign body in the eye

• Eye pain in severe cases

Many patients remain asymptomatic during the early phase, making routine eye exams essential for early detection.

Potential Risks of Untreated Eye Calcification

Ignoring symptoms or delaying treatment can have serious consequences:

Visual Impairment

Calcium plaques can interfere with light transmission through the cornea, leading to progressive visual decline and distortion.

Corneal Complications

• Ulcers and epithelial breakdown

• Increased susceptibility to secondary infections

• Permanent scarring, sometimes requiring corneal transplant

Quality of Life Impact

Chronic discomfort, light sensitivity, and reduced visual clarity can significantly affect daily activities and mental well-being.

Modern Treatment Options at Bangkok Eyes Hospital

Bangkok Eyes Hospital offers a multidisciplinary approach, utilizing advanced diagnostic tools and minimally invasive techniques to manage eye calcification effectively.

Diagnostic Process

• Slit-lamp examination – Visual assessment of surface and internal deposits

• Anterior segment imaging – High-resolution scans to determine depth and extent

• Blood work – Evaluation of systemic calcium and phosphate balance

Treatment Modalities

Medical Management

• Topical chelating agents (e.g., EDTA eye drops) help dissolve superficial calcium plaques.

• Anti-inflammatory drops to control underlying inflammation.

• Lubricating eye drops for symptom relief.

Surgical Procedures

• Superficial keratectomy – A safe, outpatient procedure to manually remove corneal calcium.

• Amniotic membrane transplantation – Restores damaged tissue in advanced cases and supports healing.

• Corneal transplant – Considered when structural integrity is severely compromised.

Long-Term Monitoring and Aftercare

• Regular follow-ups using imaging and vision tests

• Adjustment of treatment for recurrent or resistant cases

• Coordination with nephrology or endocrinology in systemic disorders

All procedures at Bangkok Eyes Hospital are performed by fellowship-trained ophthalmologists, ensuring optimal outcomes and safety.

Prevention Tips for Eye Calcification

While not always preventable, certain habits can significantly reduce risk:

Maintain Balanced Nutrition

• Avoid excessive intake of vitamin D and calcium supplements without medical supervision.

• Include foods rich in antioxidants and omega-3 fatty acids for ocular health.

Manage Chronic Conditions

• Monitor and treat kidney disease, thyroid/parathyroid dysfunction, and autoimmune disorders.

• Maintain good control of systemic inflammation and diabetes.

Practice Eye Care Hygiene

• Use preservative-free eye drops if needed regularly.

• Avoid overuse of contact lenses and follow proper cleaning protocols.

• Limit screen time and practice the 20-20-20 rule to prevent dry eyes.

Routine Eye Checkups

Early detection through annual eye exams, especially for high-risk individuals, helps catch deposits before symptoms become severe.

Frequently Asked Questions (FAQ)

What causes eye calcification?
Eye calcification is caused by a combination of systemic imbalances (like high calcium or phosphate levels), chronic eye inflammation, trauma, or certain medications.

Is eye calcification reversible?
Superficial deposits can often be removed effectively, but deeper damage may require surgery or long-term management.

Can I prevent eye calcification?
Yes, through proper eye hygiene, balanced supplementation, routine eye exams, and managing underlying health conditions.

Is surgery painful or risky?
Superficial keratectomy is a low-risk, outpatient procedure with quick recovery and minimal discomfort under local anesthesia.

How do I know if I have calcification?
You may notice blurry vision, white spots on the eye, or irritation. However, some cases are only detectable during an eye exam.
