Summary
Interstitial keratitis is an inflammation of the cornea, which is the clear front part of the eye. It occurs when the immune system mistakenly attacks the cornea, often due to infections or autoimmune diseases. This condition can cause pain, redness, and vision problems. If untreated, it can lead to scarring and vision loss.
The condition is often triggered by infections like syphilis or herpes. Genetic factors can make some people more susceptible. Environmental factors, such as exposure to certain infections, also play a role. It's important to identify and treat any underlying conditions to manage the disease.
Symptoms include eye redness, pain, and blurred vision. A unique characteristic is corneal haze, which is cloudiness in the cornea. If untreated, it can lead to corneal scarring and significant vision loss, affecting daily activities and quality of life.
It is diagnosed through a comprehensive eye exam. A slit-lamp examination, which uses a special microscope to look at the eye, helps identify corneal inflammation. Blood tests may be done to check for underlying infections or autoimmune conditions.
Preventing interstitial keratitis involves managing underlying conditions like infections. Regular eye check-ups can help detect early signs. Treatment includes medications like corticosteroids to reduce inflammation and antivirals or antibiotics to target infections.
Self-care includes regular eye check-ups and following prescribed treatments. Protecting eyes from bright light and avoiding irritants is important. A healthy diet rich in vitamins supports eye health. Avoid smoking and limit alcohol, as they can worsen symptoms.
