Interstitial Keratitis
Symptoms and Signs of Interstitial Keratitis
Photophobia, pain, lacrimation, and vision blurring are common. The lesion begins as patches of inflammation in the mid-stroma that cause opacification. Typically with syphilis and occasionally with other causes, the entire cornea develops a ground-glass appearance, obscuring the iris. New blood vessels grow in from the limbus (neovascularization) and cause orange-red areas (salmon patches). Anterior uveitis and choroiditis are common in syphilitic interstitial keratitis. Inflammation and neovascularization usually begin to subside after 1 to 2 months regardless of treatment. Some corneal opacity usually remains, causing mild to moderate vision impairment.
