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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
When the protective surface of the cornea becomes compromised, microorganisms can invade and cause infection. Common infectious causes include:
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.
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 corneal ulcers typically develop after eye injuries involving plant materials, dirt, or soil, highlighting the importance of protective eyewear and strict contact lens care.
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.
Not all corneal ulcers result from infection. Several non-infectious conditions can damage the cornea, leaving it susceptible to ulceration:
Scratches, punctures, burns, or foreign objects in the eye can damage the cornea, creating a pathway for infections or leading directly to ulceration.
Chronic dryness erodes the protective corneal surface, reducing natural defenses and increasing vulnerability to damage and subsequent ulcers.
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.
Exposure to certain chemicals or reactions to medications can irritate and damage the corneal tissue, increasing the risk of ulceration.
Autoimmune diseases, such as rheumatoid arthritis or lupus, can cause inflammation and tissue damage in the cornea, increasing the risk of ulcers.
Several risk factors increase susceptibility to corneal ulcers. Recognizing and managing these risks can significantly decrease the likelihood of developing corneal complications:
Improper use of contact lenses, including overnight wear, poor hygiene practices, or prolonged lens wear, significantly increases the risk of corneal ulcers.
Previous infections with herpes simplex virus or varicella-zoster virus can predispose individuals to recurrent corneal ulcers.
Persistent dry eyes weaken the protective tear film, making the cornea more susceptible to damage and infection.
Abnormalities or conditions that prevent complete eyelid closure expose the cornea, greatly increasing vulnerability to ulcers.
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.
Trauma or recent surgical procedures can compromise corneal integrity, creating conditions favorable for ulcer development.
Chronic diseases like diabetes can impair healing and increase susceptibility to corneal complications, including ulcers.

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:
Often, treatment involves frequent application of eye drops, sometimes as often as every hour to ensure effective control of the condition.
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.
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.
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.
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.
Washing your hands frequently and avoiding touching your eyes with unclean hands helps prevent the introduction of bacteria to the eye’s surface.
Items such as eye makeup, towels, or any products that touch the eyes should never be shared, reducing the risk of cross-contamination.
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.
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.
A rapid increase in pain could indicate that the ulcer is deepening or that the infection is spreading.
If you notice significant blurring, double vision, or a sudden loss of vision, it is important to get help immediately.
A rapidly worsening appearance of your eye in terms of redness and swelling may signal an escalating condition.
A surge in pus-like or sticky discharge is another indicator that the ulcer may be worsening.
If your eyes become increasingly sensitive to bright light, this is a cue to seek professional care
No, a corneal ulcer will not heal without medical intervention. If left untreated, the infection can progress, causing irreversible damage and even permanent vision loss.
Contact lens wearers are more prone to corneal ulcers because lenses can trap microorganisms against the eye. Sleeping in lenses or not maintaining proper cleaning routines further increases the risk.
A corneal abrasion is a superficial scratch on the corneal surface that usually heals on its own. A corneal ulcer, however, is a deeper lesion often associated with infection and requires prompt treatment.
Our cornea specialist will advise you to resume contact lens use only after your corneal ulcer has fully healed and your vision has stabilized. Following post-treatment advice is essential to prevent recurrence.
Generally, bacterial corneal ulcers are not contagious. However, viral causes of ulcers, such as those stemming from herpes simplex, can be transmitted through direct contact with infected eye secretions.
Corneal ulcers can severely affect vision if not treated promptly. Early detection, proper treatment including medications or surgery and preventive care are essential for recovery. Contact our office for personalized advice and care from our cornea specialists.
