What is Diffuse Interstitial Keratitis?

Diffuse interstitial keratitis (DIK) is a rare type of corneal inflammation that can cause significant vision loss if left untreated. It typically affects both eyes and can occur at any age, although it is more common in children and young adults.

Symptoms:

The symptoms of DIK can vary depending on the severity of the condition. Some common symptoms may include:

• Blurred vision
• Eye redness
• Light sensitivity
• Eye pain or discomfort
• Excessive tearing or discharge

DIK can also cause scarring of the cornea, which can lead to permanent vision loss if left untreated. Therefore, it is important to seek medical attention if you experience any of these symptoms.

Causes:

The exact cause of DIK is unknown, but it is believed to be an autoimmune disorder. This means that the body's immune system mistakenly attacks the cornea, causing inflammation and damage.

DIK can also be associated with certain infections, such as syphilis or tuberculosis, although these cases are rare. In some cases, the condition may be genetic and can run in families.

Treatment:

Treatment for DIK typically involves the use of topical and oral corticosteroids to reduce inflammation. In severe cases, a corneal transplant may be necessary to restore vision.

1. Topical corticosteroids:

Eye drops or ointments containing corticosteroids can be used to reduce inflammation and relieve symptoms. These medications should only be used under the supervision of an eye doctor, as prolonged use can cause side effects such as glaucoma or cataracts.

2. Oral corticosteroids:

In some cases, oral corticosteroids may be prescribed to reduce inflammation throughout the body. These medications can have more significant side effects, so they should only be used under close medical supervision.

3. Corneal transplant:

If the cornea has been severely damaged by DIK, a corneal transplant may be necessary to restore vision. During this procedure, a donor cornea is surgically implanted into the affected eye.

Conclusion:

Diffuse interstitial keratitis is a rare but serious condition that can cause significant vision loss if left untreated. If you experience any symptoms of DIK, it is important to seek medical attention immediately. With proper treatment, many people with DIK are able to manage their symptoms and preserve their vision.
