What are the symptoms of keratitis?

　　Keratitis is one of the most common ophthalmic conditions encountered in daily life and is closely associated with poor ocular hygiene. Frequently rubbing the eyes with unwashed hands can easily lead to keratitis. Similarly, improper use of contact lenses is also a common cause. Early symptoms of keratitis are often overlooked, resulting in prolonged disease duration for most patients. So, what are the symptoms of keratitis?

　　What Are the Symptoms of Keratitis?

　　Keratitis typically presents with eye pain and photophobia. The pain is usually prominent—initially mild but progressively intensifying—and tends to be persistent. It is often accompanied by a pronounced sensation of dryness. Following onset, patients become highly sensitive to light; even moderately bright illumination may make it difficult to open the eyes, and light exposure may further exacerbate the pain. Many patients must wear sunglasses when going outdoors, otherwise normal outdoor activities become impossible.

　　Keratitis can be treated through pharmacotherapy, surgery, or other modalities. Most cases respond well to medication. Topical antimicrobial eye drops are commonly prescribed—for example, 0.5% miconazole eye drops or direct application of acyclovir to the eye. In severe cases, oral acyclovir tablets may be administered, sometimes in combination with corticosteroids. Surgical intervention is reserved for patients with extremely severe manifestations, such as corneal perforation secondary to inflammation, which requires surgical repair.

　　In daily life, avoid spicy foods and alcohol, and increase intake of fruits and vegetables. We hope this information proves helpful to you.
