What Is Acute Keratitis?

Acute keratitis is an inflammation of the cornea, the transparent front part of the eye. Depending on the infectious agent, acute keratitis can be classified into bacterial keratitis, viral keratitis, fungal keratitis, and other types. Treatment typically involves antibiotics or the use of certain eye drops to relieve symptoms. After developing acute keratitis, patients should pay attention to proper eye usage—avoiding excessive use of electronic devices and refraining from rubbing their eyes—to prevent worsening of the condition.

The cornea is essentially the black, circular, transparent tissue at the front of the eyeball. It forms part of the eye's refractive system and acts as a protective barrier against external threats. When the cornea’s defensive capabilities are weakened and exogenous or endogenous pathogens invade the corneal tissue, causing inflammation, this condition is known as keratitis. Keratitis can result from various causes, including infections, immune-related disorders, nutritional deficiencies, neurotrophic conditions, or exposure to environmental factors. Treatments for keratitis vary depending on the underlying cause.

Once the specific cause is identified, targeted treatment can be administered. Generally, acute keratitis is primarily caused by bacterial infection. Because bacterial keratitis often has a sudden onset and progresses rapidly, many people commonly refer to it as acute keratitis. We hope this answer has been helpful to you.
