Keratitis is a prevalent condition characterized by the inflammation of the cornea, which is the clear layer that covers the front of the eye. The cornea plays a vital role in the eye’s functionality, as it is responsible for bending light rays and contributes to approximately two-thirds of the eye’s total power. This delicate membrane is approximately 0.5 millimeters thick and resides on top of a fluid called aqueous humor. When the cornea becomes inflamed, it can lead to symptoms such as redness, pain, and blurred vision.
Recognizing the Symptoms of Keratitis
Keratitis is accompanied by several noticeable symptoms. These include eye redness, pain, excessive tearing or discharge, difficulty opening the eye due to pain or swelling, and blurred or decreased vision. Additionally, individuals with keratitis may experience photophobia, which is an increased sensitivity to light. In the early stages of the condition, it may feel as though there is something in the eye, even though there is no debris present.
Can an injury lead to keratitis?
Keratitis, a condition that causes inflammation of the cornea, can be caused by various factors, and eye injury is one of the leading causes. Although infections often contribute to the development of eye disorders, keratitis can occur even without an infection. In particular, a scratch or puncture to the cornea can create a breeding ground for bacteria or fungi, leading to an infection and raising the risk of keratitis.
