A corneal ulcer is an open sore on the cornea—the clear, dome-shaped surface that covers the front of the eye. It typically results from an infection, often due to bacteria, viruses, or fungi. Corneal ulcers are serious eye conditions that can lead to vision loss if not treated promptly. Early diagnosis and treatment are crucial to prevent permanent damage to the eye.
Prompt treatment is essential to prevent vision loss.
Eye doctors diagnose corneal ulcers through a thorough eye examination, including the use of fluorescein dye to highlight the ulcer. A slit-lamp microscope helps examine the cornea in detail. In some cases, samples may be taken from the eye to identify the specific cause of the infection. Quick and accurate diagnosis is vital for effective treatment and to prevent vision complications.
If left untreated, corneal ulcers can lead to serious complications including corneal scarring, perforation, vision loss, or even loss of the eye. The infection can spread quickly, causing irreversible damage. Prompt medical care can prevent these risks and protect your vision. Even minor symptoms should not be ignored, as ulcers can progress rapidly.
Seek medical attention immediately if you experience sudden eye pain, redness, blurry vision, or light sensitivity—especially if you wear contact lenses. A white spot on the cornea or discharge from the eye are also warning signs. Early intervention is key to preventing vision damage and speeding up recovery from a corneal ulcer.
Prevention involves maintaining good eye hygiene, especially for contact lens users. Always wash hands before handling lenses, avoid overnight wear, and use proper lens cleaning solutions. Protective eyewear should be worn during sports or activities that pose a risk to the eyes. Managing dry eyes or eyelid conditions can also reduce the risk of ulcers developing.
