Mooren keratitis is a chronic, inflammatory disease that affects the periphery (edge) of the cornea (the clear dome at the front of the eye). While this disease can affect both eyes, it usually occurs in only one eye. Although the exact cause of Mooren keratitis is unknown, it is thought to be related to the immune system abnormally attacking the cornea.
Mooren Keratitis: What Causes It?
Although the exact cause of Mooren keratitis is unknown, it is thought to be related to the immune system abnormally attacking the cornea. This condition can result from various factors such as autoimmune diseases, infections, or exposure to certain drugs.
Autoimmune diseases: Having autoimmune diseases like lupus, rheumatoid arthritis, and ankylosing spondylitis can increase the risk of Mooren keratitis.
Infections: Some bacterial infections, such as tuberculosis and syphilis, can also lead to Mooren keratitis.
Drugs: Certain drugs, such as hydralazine and amiodarone, can contribute to the development of Mooren keratitis.
What Are the Symptoms of Mooren Keratitis?
The symptoms of Mooren keratitis usually develop slowly and can include:
- eye pain
- redness
- increased tearing
- light sensitivity
- blurred vision
- drooping eyelid
How to Diagnose Mooren Keratitis?
Doctors diagnose Mooren keratitis through an eye examination and review of the patient’s medical history. The doctor may use a spray to dilate the pupil (magnifying glass) and a fluorescein dye to examine the cornea in more detail. In some cases, blood tests or imaging tests may be required to determine the cause of Mooren keratitis.
How to Treat Mooren Keratitis?
The treatment for Mooren keratitis depends on the severity and cause of the disease. Mild cases can be treated with anti-inflammatory medications such as corticosteroid drops or ointments. More severe cases may require systemic steroids, immunosuppressive drugs, or other treatments like photodynamic therapy. Treating Mooren keratitis can be long-term, and there is a risk of recurrence.
How to Manage Mooren Keratitis?
In addition to treating Mooren keratitis, some steps can help delay the progression of the disease and prevent vision loss. These steps may include:
Protecting your eyes from the sun: Sunlight can worsen the symptoms of Mooren keratitis. Therefore, it is important to wear sunglasses when going outside.
Avoiding irritants: Stay away from substances that can irritate your eyes, such as smoke, dust, and chemicals.
Washing your hands frequently: Wash your hands thoroughly with soap and water before and after touching your eyes. This reduces the risk of infection.
Using artificial tears prescribed by your eye doctor: Artificial tear drops can relieve dryness in the eyes.
Regularly visiting your eye doctor: Your eye doctor can closely monitor the treatment of Mooren keratitis and check for any complications.
