Corneal Ulcer

A corneal ulcer is an open sore that develops on the cornea, the clear, dome-shaped surface of the eye that helps focus light. Corneal ulcers are most commonly caused by infections from bacteria, viruses, fungi, or parasites. They can also result from dry eyes, trauma, or prolonged contact lens use. If left untreated, corneal ulcers can lead to severe complications, including vision loss or blindness. Early diagnosis and treatment are crucial to prevent further damage to the eye.


Symptoms of a corneal ulcer can develop rapidly and may include:

  • Eye redness and pain
  • Sensitivity to light (photophobia)
  • Watery or thick eye discharge
  • Blurred or decreased vision
  • Sensation of a foreign body in the eye
  • Swelling of the eyelids
  • White or gray spot visible on the cornea

Consult our Ophthalmology​ experts if you experience:

  • Persistent eye pain that worsens
  • Severe eye redness or swelling
  • Sensitivity to light
  • Sudden decrease in vision
  • Discharge from the eye
Prompt treatment can help prevent permanent damage and restore vision.​

Your time with your doctor may be limited, so make sure to prepare for your visit beforehand. Here are some tips to help get you started.​​

To diagnose a corneal ulcer, the following tests may be performed:

  • Slit-lamp examination: A magnified view of the eye to detect the ulcer.
  • Fluorescein stain test: A special dye used to highlight the ulcer on the cornea.
  • Microbial culture: A sample from the ulcer to identify the causative organism and determine the appropriate treatment.
  • Visual acuity test: To assess the impact of the ulcer on vision.​

Treatment for corneal ulcers depends on the cause and severity of the condition and may include:

  • Antibiotic, antifungal, or antiviral eye drops: To treat the underlying infection.
  • Pain relief medications: Eye drops or oral medications to alleviate discomfort.
  • Artificial tears: To keep the eye lubricated and aid healing.
  • Eye patching: To protect the eye during recovery.
  • Surgery: In severe cases, a corneal transplant may be needed to restore vision.​
