Corneal Ulcers, often described as open sores on the eye’s outer layer, manifest as redness and pain. 

These Ulcers occur due to various factors, including infections caused by bacteria, viruses, or fungi. 

Swift recognition and understanding of their origins are paramount in preventing severe complications. 

This article talks about Corneal Ulcers, shedding light on their appearance, causes, and the importance of early intervention.

What are the symptoms of a Corneal Ulcer

Corneal ulcers can result in vision loss and even blindness, requiring urgent medical attention. 

If you experience these symptoms, seek immediate help from your eye care provider: 

  • Redness and irritation: Your eye turns red, becomes teary, and appears bloodshot – a trio of telltale signs
  • Intense eye pain: An ache deep within your eye intensifies, signaling trouble beneath the surface
  • Foreign sensation: A persistent feeling, like something foreign, lodged in your eye, needs attention
  • Light sensitivity: Light, once friendly, now triggers discomfort, making you squint and shield your eye
  • Blurred vision: Your clear view turns hazy, with the world appearing like an intricate puzzle that’s hard to solve
  • Swollen eyelids: Eyelids unexpectedly puff up, making you question the familiar contours of your eyes
  • Pus or unusual discharge: Unconventional eye discharges, including pus, appear, prompting concern
  • One-eyed focus: Corneal Ulcers usually pick one eye as their stage, focusing their antics on that sole actor

Corneal Ulcers vs. Corneal Abrasions:

  • Ulcers are deep sores from infection, needing intensive treatment and daily checkups. They can cause serious vision issues.
  • Abrasions are shallow scrapes healing swiftly with antibiotics. Often confused with Ulcers due to similar symptoms but treated differently.

    • Causes of Corneal Ulcer: Unveiling the culprits

    A Corneal Ulcer is an open sore or infection in the Corneal epithelium.

    It occurs when bacteria, viruses, or fungi enter the Cornea, causing inflammation and ulceration.

    According to Zhongwen Li et al, Corneal Ulcers are a leading cause of worldwide Corneal blindness.

    They can also arise from non-infectious sources, like minor injuries or autoimmune diseases.

    Infections are the primary causes of Corneal Ulcers.

    Several infections can lead to Ulcers, including:

    Bacterial infections

    Bacterial Ulcers result from bacteria infiltrating a cracked Corneal barrier.

    American Academy of Ophthalmology (AAO) reports it’s common among contact lens wearers, especially those who wear lenses for extended periods or don’t care for them properly.

    While any bacteria can cause Keratitis, mainly:

    • Micrococcaceae
    • Streptococcaceae 
    • Pseudomonas 
    • Enterobacteriaceae 

    They contribute to about 80% of bacterial keratitis cases.

    Injuries like scratches or chemical burns, can also lead to bacterial infections.

    Viral infections

    Viruses can trigger Shingles and Herpes Simplex Keratitis.

    Herpes Simplex Keratitis is recurring and highly contagious.

    Viral flare-ups can be caused by stress, trauma, fever, and certain drugs, which weaken the immune system.

    Fungal infections

    Fungi can cause infections after a corneal injury involving plants or plant material.

    Injured Corneas become vulnerable to fungal pathogens.

    Weakened immune systems also increase the risk, especially in humid conditions during monsoons and early winter.

    Parasitic infections

    Parasites like amoebas can damage the Cornea, especially for contact lens wearers.

    Acanthamoeba and Microsporidia are common parasitic causes. 

    Other factors causing Corneal Ulcers

    Head Injury
    Head Injury

    Other than infectious causes as discussed above, the following are some non-infectious causes of Corneal Ulcers:

    • Eyelid hindrance: Conditions like Bell’s palsy can prevent eyelids from fully closing, leaving the eye vulnerable
    • Dry eyes dilemma: Dry eyes can also set the stage for Corneal Ulcers
    • Injury insight: An eye injury like a scratch, cut, or chemical burn can turn problematic if infected by bacteria
    • Allergic alarms: Severe allergic eye conditions aren’t to be underestimated
    • Inflammatory intricacies: Various inflammatory disorders also contribute to the risk

    As we explore the intricacies of Corneal Ulcers, remember these triggers are like puzzle pieces that come together to form a complex picture.

    By understanding them, we empower ourselves to take proactive measures to preserve our precious eyes’ well-being.

    Diagnosing Corneal Ulcer: Illuminating the detection process

    The diagnosis of a Corneal Ulcer unfolds under the guidance of eye care specialists.

    They will perform a regular eye checkup, which includes reviewing the patient’s medical history, recent eye injuries, and contact lens usage.

    In addition to the standard eye exam, advanced technologies are used to assess the patient’s eye condition thoroughly.

    These include:

    Fluorescein stain

    Cornea Checkup
    Cornea Checkup

    Dye-infused eye drops are administered to accentuate Corneal damage.

    Subsequently, a specialized microscope known as a slit lamp is employed to determine whether the observed damage corresponds to an Ulcer. 

    Cultures of Ulcer scrapings

    After inducing numbness with eye drops, a minute sample is extracted from the Ulcer. 

    Polymerase Chain Reaction (PCR) testing is also performed to detect the presence of herpes virus DNA. 

    Confocal microscopy

    A high-resolution microscope is used to scan the Cornea, generating intricate images of individual cells. 

    This technique aids in the identification of fungi and Acanthamoeba contributing to the eye infection

    High-definition photography

    Through digital photography, highly detailed images of the Cornea and other ocular structures are captured. 

    These images function as baseline assessments and facilitate the monitoring of Cornea Ulcer improvement throughout the treatment course. 

    These advanced diagnostics equip medical professionals with comprehensive insights. 

    These insights form the cornerstone of the patient’s diagnosis and guide the development of a meticulously tailored treatment plan.

    Warning:
    Failure to seek timely treatment can result in complications and potential vision loss. Don’t wait – prioritize your eye health.

    Unveiling the underlying conditions

    A deeper dive is undertaken to verify or dismiss rare systemic conditions that may underlie Corneal Ulcers, including Tuberculosis (TB) or Syphilis. 

    The tests for these conditions encompass:

    • Tuberculin skin test: The test discerns prior exposure to TB
    • TB blood test: This test measures the patient’s immune response to TB bacteria
    • Blood, fluid, or tissue samples: These samples are scrutinized to identify the presence of antibodies to Syphilis bacteria or the bacteria itself

    Eye care experts have an important role in getting the diagnosis right. 

    They use their special knowledge to understand what’s happening in your eye. 

    It’s really important to see them quickly if you have any eye problems. 

    This helps stop things from getting worse and causing more trouble.

    Treatment choices for Corneal Ulcer: Starting the healing journey

    Once the diagnosis and cause of a Corneal Ulcer are confirmed, treatment begins promptly. 

    Acting quickly can reduce the chance of Corneal scarring linked to the underlying issue.

    Ophthalmologists commonly employ these treatments for Corneal Ulcers:

    Antibiotic eye drops or ointments

    The primary approach involves using antibiotic eye drops or ointments. 

    These combat the infection-causing bacteria and reduce inflammation. 

    Treatment duration depends on the infection’s severity.

    Steroid eye drops

    Sometimes, steroid eye drops help reduce inflammation and speed up healing. 

    However, these must be used carefully under an eye doctor’s supervision to prevent complications.

    Oral antibiotics

    Oral antibiotics are considered for severe Ulcers or if the bacteria are resistant to topical antibiotics. 

    Taken by mouth, they combat the infection from within.

    Corneal patch

    A protective eye patch might be applied alongside antibiotic drops or ointments to aid healing and shield the Cornea.

    Corneal transplant

    For severe cases with extensive corneal damage, a transplant could be necessary. 

    This procedure replaces damaged Cornea parts with healthy donor tissue.

    With timely treatment, most Corneal Ulcers improve within 2 or 3 weeks.

    But, a Corneal Ulcer is a serious matter that can harm vision and lead to long-term damage. 

    If ignored and left untreated, it might cause:

    • Scars on the Cornea
    • Severe vision impairment and even blindness
    • Rarely, loss of the eye
    • Corneal holes
    • Cataracts
    • Glaucoma

    In cases where vision is impaired due to scars, a corneal transplant might be necessary.
