Corneal Ulcers: Causes, Diagnosis, and Treatment

Corneal ulcers are open sores on the clear, dome-shaped surface that covers the front of your eye, and they require immediate attention to prevent lasting damage.Damage to this vital tissue—whether from infection, injury, or other conditions—can quickly escalate into a serious eye emergency. Our cornea specialists emphasize that prompt diagnosis and treatment are key to protecting your vision.

Symptoms and Signs of Corneal Ulcers

Understanding the symptoms and recognizing the signs of corneal ulcers can lead to early diagnosis and prompt treatment, essential for preserving vision and preventing serious complications. Corneal ulcers typically present distinct and noticeable symptoms, and patients experiencing any of these signs should seek evaluation by our corneal specialist without delay.

Eye Pain and Discomfort

One of the most prominent symptoms of a corneal ulcer is significant eye pain, which often feels sharp, aching, or throbbing. The pain usually worsens with blinking or when exposed to bright light. Severe pain can signal deeper involvement of the cornea and requires immediate attention.

Redness and Inflammation

Corneal ulcers typically cause pronounced eye redness, often accompanied by noticeable inflammation and swelling around the eyelids. This redness appears distinct, bright, and concentrated around the cornea, indicating active irritation or infection.

Blurred Vision and Vision Changes

A common symptom of corneal ulcers is blurred or distorted vision. Patients may experience difficulty focusing clearly, with images appearing cloudy, hazy, or less sharp. In advanced cases, severe vision loss can occur, underscoring the urgency of evaluation and treatment.

Light Sensitivity (Photophobia)

Patients with corneal ulcers frequently report heightened sensitivity to light (photophobia). Exposure to normal daylight or indoor lighting may trigger intense discomfort or sharp pain, leading many patients to prefer dim environments or wear sunglasses indoors.

Eye Discharge and Tearing

Corneal ulcers often lead to increased tearing or watery discharge, sometimes accompanied by thick mucus or pus. Discharge can be particularly heavy in bacterial infections, causing crusting of the eyelids or lashes, especially upon waking.

Foreign Body Sensation

Patients frequently describe the sensation of having sand, grit, or another foreign object in their eye. This gritty sensation results from irritation of nerve endings on the corneal surface, which become sensitive and inflamed due to the ulceration.

White Spot on the Cornea

A visible white or grayish-white spot may appear on the surface of the cornea, particularly if the ulcer is advanced or severe. This opacity represents areas of active infection, inflammation, or tissue breakdown, clearly visible upon close inspection.

Swelling of the Eyelids

Eyelid swelling is another common symptom, occurring in response to the underlying inflammation or infection. The lids may appear noticeably puffy or feel heavier than usual, contributing to overall discomfort and difficulty fully opening the affected eye.

Reduced Corneal Clarity

The cornea usually appears transparent and clear; however, during an ulcerative process, it may lose this transparency, appearing cloudy or opaque. This loss of clarity is a strong indicator of a corneal ulcer and necessitates immediate specialist assessment.

Change in Pupil Appearance

In severe cases, corneal ulcers can affect pupil shape or appearance. The pupil may appear irregular, smaller, or distorted due to underlying inflammation and swelling, highlighting the severity and potential risks associated with untreated ulcers.

Recognizing any combination of these symptoms should prompt immediate consultation with a corneal specialist, as timely diagnosis and intervention are crucial for optimal outcomes and the preservation of vision.

Causes and Risk Factors for Corneal Ulcers

Understanding the underlying causes and risk factors associated with corneal ulcers can help in prevention and early detection. Corneal ulcers can result from both infectious and non-infectious factors, with certain habits and medical conditions significantly increasing the risk.

Infectious Causes of Corneal Ulcers

When the protective surface of the cornea becomes compromised, microorganisms can invade and cause infection. Common infectious causes include:

Bacterial Infections

Bacterial infections, commonly involving organisms such as Pseudomonas, Staphylococcus, and Streptococcus, often occur in contact lens wearers, especially those who do not adhere to proper lens hygiene or who sleep in their lenses.

Viral Infections

Viruses like herpes simplex (cold sores) or varicella-zoster (shingles) can cause corneal ulcers, particularly during active flare-ups. These infections often recur, posing ongoing risk.

Fungal Infections

Fungal corneal ulcers typically develop after eye injuries involving plant materials, dirt, or soil, highlighting the importance of protective eyewear and strict contact lens care.

Parasitic Infections (Acanthamoeba)

Acanthamoeba, a parasite found in tap water and natural bodies of water, can cause severe corneal ulcers, especially among contact lens wearers who swim or rinse their lenses with non-sterile water.

Non-Infectious Causes of Corneal Ulcers

Not all corneal ulcers result from infection. Several non-infectious conditions can damage the cornea, leaving it susceptible to ulceration:

Eye Injuries and Trauma

Scratches, punctures, burns, or foreign objects in the eye can damage the cornea, creating a pathway for infections or leading directly to ulceration.

Dry Eye Syndrome

Chronic dryness erodes the protective corneal surface, reducing natural defenses and increasing vulnerability to damage and subsequent ulcers.

Incomplete Eyelid Closure

Conditions such as Bell’s palsy, which prevent proper eyelid closure, leave the cornea exposed, significantly raising the risk of ulcers due to environmental irritants and dryness.

Toxic Reactions

Exposure to certain chemicals or reactions to medications can irritate and damage the corneal tissue, increasing the risk of ulceration.

Autoimmune Disorders

Autoimmune diseases, such as rheumatoid arthritis or lupus, can cause inflammation and tissue damage in the cornea, increasing the risk of ulcers.

Risk Factors for Corneal Ulcers

Risk Factors for Corneal Ulcers

Several risk factors increase susceptibility to corneal ulcers. Recognizing and managing these risks can significantly decrease the likelihood of developing corneal complications:

Contact Lens Wear

Improper use of contact lenses, including overnight wear, poor hygiene practices, or prolonged lens wear, significantly increases the risk of corneal ulcers.

History of Eye Infections

Previous infections with herpes simplex virus or varicella-zoster virus can predispose individuals to recurrent corneal ulcers.

Chronic Dry Eyes

Persistent dry eyes weaken the protective tear film, making the cornea more susceptible to damage and infection.

Eyelid Abnormalities

Abnormalities or conditions that prevent complete eyelid closure expose the cornea, greatly increasing vulnerability to ulcers.

Use of Steroid Eye Drops

Long-term or frequent use of steroid-containing eye drops can reduce the cornea's immune response, making it easier for infections to develop and persist.

Recent Eye Injury or Surgery

Trauma or recent surgical procedures can compromise corneal integrity, creating conditions favorable for ulcer development.

Systemic Health Conditions

Chronic diseases like diabetes can impair healing and increase susceptibility to corneal complications, including ulcers.

Treatment Options

Treatment Options

Medications

Medications make up the cornerstone of corneal ulcer treatment. They help control the infection and manage symptoms, giving the cornea a better chance to heal:

  • Antibiotic Eye Drops: These are prescribed for bacterial infections and work to eliminate the harmful bacteria quickly.
  • Antiviral Medications: When a virus is the culprit—such as herpes simplex—antiviral drops or oral medications help keep the infection under control.
  • Antifungal Treatments: For fungal causes, specific antifungal drops or tablets are necessary to combat the infection.
  • Anti-inflammatory Drops: In some cases, corticosteroid eye drops may be used after the infection is under control to reduce inflammation and minimize scarring, though they are used with caution.
  • Pain Relievers: Over-the-counter options like ibuprofen may be recommended to alleviate discomfort and reduce inflammation.

Often, treatment involves frequent application of eye drops—sometimes as often as every hour—to ensure effective control of the condition.

Surgical Interventions

In severe cases where medications do not fully control the ulcer or when there is significant corneal scarring, surgical intervention may be considered. Although surgery is usually a last resort, it can be vital for preserving vision.

  • Corneal Transplant: For extensive damage, a transplant involves replacing the damaged corneal tissue with healthy donor tissue, which can restore clarity and function to your vision.
  • Debridement: This procedure involves carefully removing the infected or damaged tissue from the corneal surface to help reduce the infection and promote healing.

Prevention Strategies

Preventing a corneal ulcer is always preferable to treating one. There are several practical steps you can take to protect your eyes, especially if you wear contact lenses or work in high-risk environments.

Maintain Excellent Contact Lens Hygiene

Always clean and store your lenses as recommended, and never wear them overnight unless instructed by our cornea specialists. Use only approved solutions and avoid tap water when handling your lenses.

Wear Protective Eyewear

Whether you’re playing sports, gardening, or working with chemicals, using safety glasses or goggles can significantly reduce the risk of eye injuries that could lead to ulcers.

Practice Good Hand Hygiene

Washing your hands frequently and avoiding touching your eyes with unclean hands helps prevent the introduction of bacteria to the eye’s surface.

Avoid Sharing Personal Items

Items such as eye makeup, towels, or any products that touch the eyes should never be shared, reducing the risk of cross-contamination.

Seek Timely Treatment

Any eye injury or early sign of infection should be evaluated by our cornea specialists immediately. Quick intervention can prevent a minor issue from developing into a full-blown corneal ulcer. Managing and recovering from a corneal ulcer requires careful adherence to your treatment plan and lifestyle adjustments during the healing process. Our cornea specialists will provide you with detailed instructions and support throughout your recovery.

During treatment, it is crucial to follow all prescribed recommendations: use medications as directed, avoid contact lens use until our cornea specialist advises otherwise, and maintain excellent cleanliness to prevent further complications. Attending follow-up appointments is essential to monitor the healing process and make any necessary adjustments to your treatment plan.

When to Seek Emergency Care

Because corneal ulcers can develop quickly and threaten your vision, recognizing when to seek immediate care is critical. Do not hesitate to call our office if you experience any sudden or severe symptoms.
