Corneal Infection Symptoms Need Prompt Care

Treatment for corneal infection can relieve symptoms, address the underlying infection, and help protect your vision. 

  • Eye pain or worsening discomfort
  • Redness
  • Sudden blurred or decreased vision
  • Sensitivity to light
  • Excessive tearing or discharge
  • A persistent gritty or foreign-body sensation
  • A white or cloudy spot on the cornea

Do not wait for severe symptoms, reuse contact lenses, or treat the eye with leftover prescription drops. If symptoms occur after business hours, seek emergency eye care or visit the nearest emergency care center.

What Is a Corneal Infection?

The cornea is the clear tissue covering the front of the eye. A corneal infection develops when bacteria, fungi, viruses, or parasites enter the cornea and damage it.

Infectious keratitis is inflammation caused by an infection. Some infections can cause a corneal ulcer, an open sore on the corneal surface. Without prompt treatment, an infection may cause scarring, corneal thinning, or permanent vision loss.

Barnet Dulaney Perkins Eye Center provides specialized cornea care throughout Arizona for conditions affecting the health and clarity of the cornea.

Common Causes of Corneal Infections

1

Bacterial Infections

Bacteria can enter the cornea through contact lens misuse, eye injuries, or existing eye conditions, causing inflammation and infection.
2

Viral Infections

Viruses such as herpes simplex and varicella-zoster can infect the cornea, potentially causing painful sores and vision changes.
3

Fungal Infections

Fungi can infect the cornea after an eye injury involving plant material or exposure to contaminated water or soil.
4

Parasitic Infections

Parasites such as Acanthamoeba can cause serious corneal infections, often associated with improper contact lens hygiene or exposure to contaminated water.

5

Contact Lens Overuse

Wearing contact lenses for too long, sleeping in them, or failing to clean them properly can increase the risk of corneal infections.

6

Eye Injuries

Scratches or other damage to the cornea can allow harmful microorganisms to enter and cause infection.
7

Dry Eye Disease

Severe dry eye syndrome can compromise the cornea’s natural defenses, increasing susceptibility to infection.
8

Poor Eye Hygiene

Touching the eyes with unwashed hands or using contaminated eye products can introduce infectious organisms to the cornea.
9

Compromised Immune System

Conditions or medications that weaken the immune system can make it harder for the body to fight off corneal infections.
10

Contaminated Water Exposure

Swimming in pools, lakes, or hot tubs, especially while wearing contact lenses, can expose the eyes to microorganisms that cause keratitis.

How Corneal Infections Are Diagnosed

An eye doctor will examine your cornea and ask about your symptoms, contact lens habits, recent injuries, exposure to water, and medications.

Testing may include:

  • A visual acuity test
  • A slit-lamp examination
  • Fluorescein dye to identify corneal damage
  • A corneal scraping or culture to identify the organism
  • Additional laboratory or imaging tests for unusual or severe infections

Identifying the cause helps your eye doctor select an appropriate treatment.

Treatment depends on whether bacteria, fungi, viruses, or parasites caused the infection. Your treatment plan may include:

  • Antibiotic eye drops
  • Antifungal medication
  • Antiviral medication
  • Antiparasitic medication
  • Oral medication in certain cases
  • Lubrication or other care to support corneal healing

Some infections require frequent medication and close follow-up examinations.

Do not use steroid eye drops unless an eye doctor specifically directs you. Steroids can worsen certain infections or delay healing when used incorrectly.

Severe infections that cause significant scarring, corneal thinning, or perforation may require additional procedures or even corneal surgery.

Recovery and Follow-Up

Recovery time depends on the organism, infection severity, treatment response, and overall eye health. Keep every follow-up appointment, even if your eye begins to feel better.

During recovery:

  • Use medication exactly as directed
  • Do not stop treatment early
  • Avoid contact lenses until your eye doctor clears you
  • Do not rub or touch the affected eye
  • Call immediately if pain, redness, discharge, or vision worsens

Your Barnet Dulaney Perkins Eye Center doctor will monitor the infection’s resolution and whether additional care is needed for scarring or vision changes.

FAQ: Corneal Infection Treatment

A possible corneal infection requires prompt evaluation because it can damage the cornea and threaten vision. Call Barnet Dulaney Perkins Eye Center promptly if you have eye pain, redness, light sensitivity, discharge, or sudden blurry vision. If symptoms are severe or occur after business hours, seek emergency eye care.

No. Keratitis means inflammation of the cornea and can be infectious or noninfectious. An eye examination is necessary to determine the cause and appropriate treatment.

Contact lenses can increase the risk of infection, especially when worn overnight, exposed to water, used beyond their replacement schedule, or handled improperly. Remove your lenses and call an eye doctor if symptoms develop.

Treatment may include antibiotic, antifungal, antiviral, or antiparasitic medication. The correct treatment depends on the cause, severity, and examination findings.

Yes. A severe or untreated infection can cause corneal scarring, thinning, perforation, and permanent vision loss. Early diagnosis and treatment can reduce these risks.

Do not resume contact lens wear until your eye doctor confirms that the infection has resolved and the cornea has healed. You may also need new lenses, a new storage case, or revised lens-care instructions.
