Idiopathic linear interstitial keratitis (ILIK) is a rare, chronic, inflammatory eye disorder that affects the cornea, the clear, dome-shaped surface that covers the front of the eye. It is characterized by a linear pattern of inflammation along the cornea, which can cause vision loss and scarring. The exact cause of ILIK is unknown, but it is thought to be an autoimmune disorder. Treatment typically involves the use of topical steroids and other medications to reduce inflammation and improve vision.

The most common symptoms of Idiopathic linear interstitial keratitis (ILIK) include:

• Pain and Redness in the affected eye

• Blurred vision

• Sensitivity to light

• Watery eyes

• A feeling of something in the eye

• A white line or streak in the cornea

• A grayish-white haze in the cornea

• A decrease in vision

• A decrease in the ability to see colors

• A decrease in the ability to see at night

The exact cause of idiopathic linear interstitial keratitis is unknown. However, it is believed to be associated with an autoimmune response, in which the body's immune system mistakenly attacks healthy tissue. Other possible causes include viral or bacterial infections, trauma, and exposure to certain medications or chemicals.

Treatment for Idiopathic linear interstitial keratitis typically involves the use of topical corticosteroids, such as prednisolone acetate, to reduce inflammation and reduce the risk of scarring. Other treatments may include topical antibiotics, cycloplegic agents, and topical nonsteroidal anti-inflammatory drugs. In some cases, systemic immunosuppressive medications may be prescribed. In severe cases, a corneal transplant may be necessary.

Idiopathic linear interstitial keratitis is a rare condition that is not well understood. Treatment is usually aimed at controlling the inflammation and preventing further damage to the cornea. Treatment options may include topical corticosteroids, topical non-steroidal anti-inflammatory drugs, topical cyclosporine, and systemic immunosuppressants. In some cases, surgery may be necessary to remove scar tissue or to repair the cornea.
