Corneal Ulcer

A Corneal Ulcer (pronounced: kɔːrˈniːəl ˈʌlsər) is a medical condition characterized by an open sore on the cornea, the clear front surface of the eye.

Etymology

The term "Corneal Ulcer" is derived from the Latin words "cornu" meaning "horn" and "ulcus" meaning "sore".

Definition

A Corneal Ulcer is a painful, often pus-filled, lesion on the cornea, the clear front surface of the eye that covers the iris and the pupil. It is typically caused by an infection or injury, and can lead to serious complications if left untreated.

Symptoms

Symptoms of a Corneal Ulcer may include redness, pain, tearing, light sensitivity, blurred vision, a white or gray spot on the cornea, and a feeling of something in the eye.

Causes

Corneal Ulcers are most commonly caused by bacterial, viral, or fungal infections. Other causes can include dry eye, severe allergic eye disease, a foreign body in the eye, or misuse of contact lenses.

Treatment

Treatment for a Corneal Ulcer depends on the cause. It may include antibiotic, antiviral, or antifungal eye drops, pain medications, or in severe cases, a corneal transplant.
