What causes interstitial keratitis?

What causes interstitial keratitis?

This condition is often caused by infections. Syphilis is the most common cause of interstitial keratitis, but rare causes include: Autoimmune diseases, like rheumatoid arthritis and sarcoidosis.

How is interstitial keratitis treated?

Medical therapy Topical corticosteroids are the mainstay of therapy for the most common forms of interstitial keratitis and are effective both for alleviating acute symptoms of pain, discomfort and blurred vision and for reducing scarring and neovascularization.

What does interstitial keratitis look like?

Interstitial keratitis, which is rare in the US, involves chronic inflammation of the middle corneal layers. Findings include pain, tearing, decreased visual acuity, and often orange-red discoloration of the cornea and anterior uveitis.

Which stage of syphilitic keratitis has ghost vessels?

Interstitial keratitis may progress to the regression phase, during which scarring of the corneal stromal and collagen remodeling occur. The superficial vessels resorb, and the deeper vessels may constrict, resulting in the ghost vessels that are seen as a late finding of syphilitic interstitial keratitis.

Is interstitial keratitis seen in secondary syphilis?

Syphilitic keratitis is a non-ulcerative interstitial keratitis that typically manifests as a late sequela of congenital or acquired syphilis. Syphilitic keratitis is seen more commonly in patients with congenital syphilis than in those who acquire syphilis later in life.

Can keratitis be caused by autoimmune disease?

Autoimmune keratitis most commonly occurs in patients with collagen vascular diseases with rheumatoid arthritis as the most frequent cause. The cornea can be involved directly by peripheral ulcerative keratitis (PUK) or paracentral kerati- tis (PCUK).

What is interstitial and deep keratitis?

Interstitial keratitis (IK) is corneal scarring due to chronic inflammation of the corneal stroma. Interstitial means space between cells i.e. corneal stroma which lies between the epithelium and the endothelium. Keratitis means corneal inflammation.

Are Chancres painful?

Chancres are painless, and can show up in places that are hard to find — like under your foreskin, in your vagina, anus, or rectum, and rarely, on your lips or in your mouth. The sores usually last about 3 to 6 weeks and then go away on their own with or without treatment.

What is interstitial keratitis (IC)?

Interstitial keratitis is a non-ulcerative, non-suppurative, more or less vascularized inflammation of the corneal stroma. The corneal lesions result from the host response to bacterial, viral (40% of cases) or parasitic antigens, or from an autoimmune response (1% of cases) without active corneal infection.

What is nuclei necrotizing interstitial keratitis (Nik)?

Necrotizing interstitial keratitis (NIK) is a rare manifestation that is believed to be associated with live viral proliferation within the stroma. It presents with an epithelial defect, dense stromal infiltration, and progressive necrosis that often results in corneal perforation.

What are the goals of interstitial keratitis treatment?

The primary goals in the treatment of interstitial keratitis are to control local inflammation to prevent pain and visually significant scarring and to identify an underlying cause to reduce systemic sequelae of the disease.

What is interstitial keratitis caused by onchocerciasis?

Interstitial keratitis caused by onchocerciasis has been described as beginning in the peripheral cornea, followed by progressive spread centripetally. Vascularization and complete opacification of the cornea may result, but corneal thinning is not a significant feature in this condition.
