What Is The Healing Time For A Corneal Ulcer

Corneal ulcer, cornea infection from contact lens, red eye – A State of Sight #60

The time until healing depends on the cause of the ulcer and its size, location, and depth. Most appropriately treated corneal ulcers should improve within two to three weeks. Treatment may continue for longer to reduce the amount of potential scarring. Corneal ulceration is a serious condition, and with inadequate or no treatment, loss of vision and blindness may occur.

Corneal Ulcer Risk Factors

People who wear contact lenses are more likely to get corneal ulcers. This risk is 10 times higher if you use extended-wear soft contacts.

Bacteria on the lens or in your cleaning solution could get trapped under the lens. Wearing lenses for long periods can also block oxygen to your cornea, raising the chances of infection.

Scratches on the edge of your contact might scrape your cornea and leave it more open to bacterial infections. Tiny particles of dirt trapped under the contact could also scratch your cornea.

Other things that may make you more likely to have a corneal ulcer include:

  • Steroid eye drops
  • Eyelashes that grow inward
  • Eyelids that turn inward
  • Conditions that affect your eyelid and keep it from closing all the way, like Bellâs palsy
  • Chemical burns or other cornea injuries

Whats The Difference Between A Corneal Ulcer And Keratitis

These eye conditions are closely related.

A corneal ulcer is an open wound a loss of corneal tissue thats often the result of an eye infection.

Keratitis is a more general term for a group of disease processes that cause inflammation of your cornea. Eye infection, injury and wearing contact lenses too long some of the same causes of corneal ulcer also cause eye inflammation. Keratitis can lead to a corneal ulcer.

Both conditions can lead to vision loss.

A note from Cleveland Clinic

Corneal ulcers are a vision-threatening eye emergency. Even a minor eye injury can lead to a corneal ulcer. If you think you have symptoms of a corneal ulcer, contact your eye care provider right away. They will examine your eye, make the diagnosis and start treatment. If you wear contact lenses, make sure you know how to properly insert, clean and store them. Your eye care team can teach you proper techniques and answer all your other questions.

Treatment For Infectious Corneal Ulcers


The primary treatment for bacterial corneal ulcers is frequent doses of antibiotic eye drops. Most ulcers respond quickly to the medication, but it is important to continue the antibiotic drops as directed even after you start to improve.


Herpes simplex eye infections are treated with antiviral eye drops or oral antiviral medications. Herpes zoster eye infections require oral antiviral drugs.


Topical antifungal drops treat fungal corneal ulcers. For severe infections, your eye doctor may prescribe oral antifungal medication.


Therapy includes combination eye drops that are effective against amoebas. Your eye doctor may also scrape the surface layer of your cornea to remove any infected tissue. Acanthamoeba can be difficult to treat, so it is essential to follow your eye doctors instructions.

Causes Of Corneal Ulcer

LiveWell Online Magazine

People usually develop a corneal ulcer after some type of corneal trauma, which allows bacteria, viruses, fungi, or parasites to enter the cornea. This invasion causes an infection with inflammation, which worsens if left untreated.

The types of infections that can lead to a corneal ulcer include:

  • Bacterial: People who wear contact lenses are at a higher risk for developing corneal ulcers, especially if they leave extended-wear lenses in their eyes for many days or weeks.
  • Viral: Corneal ulcers can be caused by the herpes simplex virus .
  • Fungal: Improper hygiene of contact lenses or use of steroid eye drops can lead to fungal infections. They can also result from an injury to the cornea that lets plant material get into the eye, or from a suppressed immune system.
  • Parasitic: Acanthamoeba, microscopic, single-celled amoeba, are the most common amoeba in fresh water and soil. This parasite can cause severe eye infection, especially in contact lens wearers, which can lead to a corneal ulcer.

Other causes of corneal ulcers include:

  • Bell’s palsy and other eyelid disorders that prevent the eyelid from closing all the way

What Types Of Doctors Treat Corneal Ulcers

If you develop a corneal ulcer, you should be examined promptly by an ophthalmologist. An ophthalmologist is a medical doctor who is specialized in diagnosis and medical/surgical treatment of eye diseases. If the corneal ulcer is very serious or vision-threatening, your ophthalmologist may refer you to an ophthalmologist who subspecializes in diseases of the cornea.

What Is A Corneal Ulcer? | Types, Causes, Symptoms, and Treatments

By Kathleen McCoy, BS

Corneal ulcers are a fairly common eye condition that often results from an open sore on the cornea becoming infected. The cornea plays a vital role in eye health and vision. Proper treatment by an ophthalmologist is critical to prevent further damage to the eye and prevent permanent vision changes or blindness.

The ulcer may be visible to the naked eye, or the ophthalmologist may have to use special dyes and a slit-lamp to find any damaged areas on the cornea. If the eye ulcer is large, you may be able to see a gray or white spot on the eye in an area that is usually transparent or clear. Accurate self-diagnosis is impossible seek evaluation and care under an ophthalmologist as quickly as possible for best results.

While a corneal ulcer is not contagious, the infection can be. Most infections are bacterial however, corneal ulcers may also be the result of viruses, fungi, dry eye, eye injury, vitamin A deficiency, and improper contact lens cleaning and use.

Conventional treatment of an eye ulcer may include antibacterial, antifungal or antiviral eye drops, corticosteroid eye drops and pain medication. During treatment, it is vital that you dont wear contact lenses or makeup, and that you dont touch your eye. The risk for complications and the need for more invasive treatment necessitates following an ophthalmologists directions precisely.

How Does A Corneal Ulcer Occur

There are several causes of corneal ulcers in dogs.

“The most common cause is trauma.”

The most common cause is trauma. An ulcer may result from blunt trauma, such as a dog rubbing its eye on the carpet, or due to a laceration, such as a cat scratch or contact with a sharp object. Another common cause is chemical burn of the cornea. This may happen when an irritating chemical or substance such as shampoo or drywall dust gets in the eye.

Less common causes of corneal ulcers include bacterial infections, viral infections, and other diseases. These may originate in the eye or may develop secondary to a disease elsewhere in the body. Examples of other diseases that may predispose a pet to corneal ulcers include:

  • epithelial dystrophy, which is a weakening of the cornea which can be inherited in some breeds, such as Boxers
  • keratoconjunctivitis sicca in which decreased tear production leads to drying of the cornea
  • endocrine diseases, such as diabetes mellitus, Cushing’s disease , and hypothyroidism

Diagnosing Corneal Ulcers Is Important Heres Why:

If you experience symptoms of corneal ulcers, you should contact an eye care professional immediately for a complete eye exam. Untreated corneal ulcers can lead to permanent eye damage and vision loss.

During the eye exam your eye doctor will look for signs of infection. In cases in which an ulcer is not visible, eye drops that temporarily stain the eye may be used to identify the ulcer. Typically your eye doctor will use a slit lamp to look into your eye.

Regardless of the visibility of the ulcer, a yellow dye may be used to see the affected area more easily. Visual acuity tests and corneal scrapings may be used to determine the cause of the ulcer. Blood tests may be needed to rule out specific disorders and diseases.

How Are Corneal Ulcers Diagnosed

A large ulcer can be seen as a white spot on the cornea, but some ulcers can only be seen with closer investigation.

Your doctor or ophthalmologist will probably check your vision and examine the cornea using a special lamp. They might drop a small amount of dye into your eye to make any ulcer show up more clearly.

To work out what has caused any underlying infection, the ophthalmologist might take a sample scraping from the ulcer for testing.

What Is The Prognosis Of A Corneal Ulcer

The prognosis for a corneal ulcer depends on its cause, its size and location, and how rapidly it is treated together with the response to treatment. Although most corneal ulcers will cause some degree of scarring, the scar will often not cause any visual loss. If the ulcer is deep, dense, and central, scarring will cause some permanent changes in vision.

What Are The Causes Of A Corneal Ulcer

Causes of corneal ulcers include:


  • Bacterial infections. Bacterial infections are the most common cause of corneal ulcers. These infections are common in contact lens wearers who dont properly clean their contacts or wear them while sleeping. Pseudomonas aeruginosa, coagulase-negative staphylococcus and staphylococcusaureus are common bacterial causes.
  • Viral infections. Viruses that can flare up and cause corneal ulcers include cold sores and shingles .
  • Fungal infections. These infections can happen if you have an injury to your cornea followed by an infection with plant or vegetable material. Aspergillus, Fusarium, Scedosporium apiospermum, phaeohyphpmycetes and candida species are common fungal causes.
  • Parasitic infections. Acanthamoeba is an amoeba found in air, fresh water and soil. An infection, Acanthamoeba keratitis, occurs when the organism gets into your eye. This can happen if you wear contact lenses and clean your lenses with tap water instead of disinfectant solution.

What Is A Corneal Ulcer

A corneal ulcer is an open wound on your cornea, which is the transparent outer layer of your eye. The cornea is responsible for maintaining clear vision, which is why corneal ulcers are a potentially vision-threatening condition.

If you think you may have a corneal ulcer, see your eye doctor immediately. If left untreated, corneal ulcers can cause permanent scarring, vision loss, and worsen degenerative eye dieases.

Is It Possible To Prevent Corneal Ulcers

Painful, swollen eyelid

Preventing a corneal ulcer is important. Individuals should wear eye protection when using power tools or when they may be exposed to small particles that can enter the eye, like particles from a grinding wheel or a weed whacker.

Individuals who have dry eyes or whose eyelids do not close completely should use artificial teardrops to keep the eyes lubricated.

If an eye is red and irritated and worsens or does not respond to over-the-counter eyedrops within a day, contact an ophthalmologist promptly.

People wearing contact lenses should be extremely careful about the way they clean and wear those lenses. Corneal ulcers secondary to contact lenses are preventable. Always wash your hands before handling the lenses. Never use saliva to lubricate contact lenses because the mouth contains bacteria that can harm the cornea. Remove lenses from the eyes every evening and carefully clean them. Never use tap water to clean the lenses. Never sleep with contact lenses not designed for overnight wear in the eyes. Store the lenses in disinfecting solutions overnight. Remove lenses whenever the eyes are irritated and leave them out until there is no longer any irritation or redness. Regularly clean the contact lens case. Carefully read the instructions about contact lens care supplied by the lens maker. Consider using daily disposable lenses.

How Can We Treat Scced Ulcers

The aims of treatment are to remove the loose epithelium and to encourage newly formed epithelium to anchor to the underlying cornea. Occasionally these Corneal treatmentscan be performed in the conscious animal using local anaesthetic eye drops but often it is necessary to sedate the patient.

Initially, after applying local anaesthetic drops, we debride the loose epithelium from the edge of the ulcer using a cotton bud . Following this, options include:

  • Grid or punctate keratotomy: Using a small needle, scratches are made on the ulcerated region of the cornea. This treatment has a 60-70% success rate per procedure, and can be repeated every 2-3 weeks until healed.
  • Diamond burr debridement: Diamond burr debridement uses a low powered, hand-held polishing burr to brush over the ulcerated corneal surface, altering the surface to allow healing to progress. There is a reported success of around 70-80% after two weeks, with some cases requiring a second treatment.
  • Superficial keratectomy: Under an operating microscope, the top layer of the corneal ulcer is surgically removed to allow the ulcer to heal. Superficial keratectomy has a 95%+ success rate, but requires a general anaesthetic.
