Eye trauma in a person may lead to several eye conditions, among which corneal ulcers and abrasion are common.
Although both these eye conditions affect the cornea, they can happen due to several causes.
It is important to learn about the similarities and differences of these conditions to receive the appropriate treatment.
Since it affects the cornea, it may threaten one’s vision and cause severe discomfort.
This article will discuss the cornea ulcers vs abrasions debate in detail.
What are Corneal Ulcer and Corneal Abrasion
Corneal ulcer, also known as Keratitis, refers to an open sore or lesion on the cornea (clear front part of the eye).
A person mainly experiences this condition due to eye infections and may require prompt treatment.
Since infections are the main cause of this condition, leaving it untreated may lead to blindness.
On the other hand, corneal abrasion is a cut due to the scraping or scratching of the cornea’s outer layer.
The scratching causes eye trauma and can become a risk factor for causing infections.
Symptoms of Corneal Ulcers vs Abrasions
Source: razyph_from_Getty_ImagesThe American Academy of Ophthalmology (AAO) states that a person with corneal ulcers may experience several symptoms.
These symptoms include redness in the eyes, eye pain, tearing, and eye discharge.
Some people may also experience inflammation, blurred vision, and sensitivity to light (photophobia).
In the case of corneal abrasion, individuals may face symptoms like redness, pain, and watery eyes.
People with this condition may often feel like something is stuck in their eyes and also experience blurry or hazy vision.

Causes of Corneal Ulcers and Abrasions
According to research, the major cause of corneal ulcers in a person is infections due to bacteria, viruses, or fungi.
It may also happen because of a bacterial infection in one’s contact lenses.
This may lead to the formation of Keratitis and ultimately lead to corneal ulcers.
Another study states that people may experience corneal ulcers due to complications from other eye conditions like Glaucoma and Cataracts.
On the other hand, a person faces corneal abrasion when they encounter foreign particles like dust and dirt in their eyes.
A study states that when a person rubs their eyes after these particles enter their eyes, it leads to this condition.
Moreover, damaged contact lenses and scratches from fingernails or other objects may cause corneal abrasion.

Corneal Ulcers vs Corneal Abrasions Treatments
Source: RossHelenSince bacterial infections mostly cause corneal ulcers, doctors often suggest using antibiotic eye drops for infection.
Doctors may also prescribe oral medications for severe infections or artificial tears to soothe the eyes due to viral infections.
In severe cases, a person may need Penetrating keratoplasty or corneal transplantation.
Since corneal abrasion can sometimes lead to eye infections, doctors prescribe antibiotic ointments like Erythromycin to prevent it.
They may also provide patching or protective eye coverings to prevent further trauma.

Corneal Ulcer vs Abrasion
Although both corneal ulcers and abrasion affect the cornea, they have several differences.
The table below comprehensively discusses the important comparisons between these two conditions.
| Aspects | Corneal Ulcer | Corneal Abrasion |
|---|---|---|
| Definition | Open sore or lesion on the cornea’s surface | External scratch or scrape on the cornea |
| Depth of Injury | Deeper, involving layers beneath the surface | Shallow and limited to the outer layer |
| Causes | Bacterial, viral, or fungal infections | Foreign objects, trauma, contact lenses |
| Symptoms | Intense pain, redness, blurred vision, eye discharge | A sensation of a foreign object, pain, redness |
| Sensitivity to Light | Increased sensitivity | Variable sensitivity |
| Vision Impact | Severe vision impairment is possible | Temporary blurry vision |
| Treatment | Antibiotic, antiviral, antifungal medications | Antibiotic eye drops, eye protection |
| Complications and Risks | Vision loss, severe infections | Infection, delayed healing |
| Diagnostic Methods | Cultures, imaging tests | Fluorescein staining |
| Recovery Time | Longer due to deeper injury | Shorter, typically heals within days |
Conclusion
Corneal ulcer vs abrasion is a popular debate since both these conditions affect one’s cornea.
While corneal ulcer and abrasion both cause eye pain, blurry vision, and redness, corneal ulcer often produces eye discharge and tearing additionally.
A person usually experiences corneal ulcers due to eye infections, while abrasions usually happen due to trauma because of scratching or foreign bodies.
Doctors usually suggest using antibiotic eye drops or artificial tears to treat and prevent corneal ulcers and abrasions.
If you are experiencing blurry vision, it is best to consult your doctor immediately for treatment.
Frequently Asked Questions
Do both corneal ulcers and abrasion cause vision loss?
No, both corneal ulcers and abrasion do not cause vision loss. Since corneal ulcers happen at a deeper level, they can cause blindness if they remain untreated. However, if one receives prompt treatment, corneal abrasion only causes temporary blurry vision.
What precautions can prevent corneal ulcers and abrasion?
Wearing protective eyewear during high-risk activities and maintaining proper contact lens hygiene can prevent corneal ulcers and abrasion.
Individuals can also avoid rubbing their eyes excessively and immediately treat eye injuries to reduce the risk of these conditions.
How are corneal ulcers and abrasions diagnosed?
Doctors diagnose corneal ulcers through eye examinations, cultures, and imaging tests like slit-lamp exams. On the other hand, fluorescein staining, along with an eye examination to visualize and assess the extent of the scratch or scrape on the cornea, diagnoses the abrasion.
Can you develop corneal ulcers from corneal abrasion?
Yes, corneal abrasions can lead to corneal ulcers if they become infected. If they remain untreated or if bacteria penetrate the corneal surface through the abrasion, it may result in a deeper infection, forming a corneal ulcer.
What should I do if I suspect I have a corneal ulcer or abrasion?
If you suspect having a corneal ulcer or abrasion, it is best to avoid rubbing the eyes. Rinsing the eyes gently can reduce the discomfort, and then it is best to consult a doctor immediately.
