Marginal Corneal Ulcer: Causes, Symptoms, and Treatment

Marginal corneal ulcer is a serious eye condition that affects the outer layer of the eye, specifically the cornea. It is a painful and potentially vision-threatening condition that requires immediate medical attention. In this article, we will discuss the causes, symptoms, and treatment of marginal corneal ulcer.


There are several potential causes of marginal corneal ulcer. One of the most common causes is bacterial infection. When bacteria enter the eye, they can cause inflammation and damage to the cornea, leading to the development of an ulcer. Other potential causes of marginal corneal ulcer include viral infections, fungal infections, and dry eye syndrome.


The symptoms of marginal corneal ulcer can vary depending on the severity of the condition. Some of the most common symptoms include:

  1. Pain or discomfort in the affected eye
  2. Redness and swelling of the eye
  3. Blurry vision or vision loss
  4. Sensitivity to light
  5. Inability to open the eye fully

Treatment for marginal corneal ulcer typically involves addressing the underlying cause of the condition. If the ulcer is caused by a bacterial infection, antibiotics may be prescribed to eliminate the infection. If the ulcer is caused by a viral or fungal infection, antiviral or antifungal medications may be used instead. In some cases, surgery may be necessary to remove the damaged tissue and promote healing.

In addition to medical treatment, there are several things you can do at home to help manage your symptoms and promote healing. These include:

  1. Using artificial tears to keep the eye moist
  2. Avoiding rubbing or touching the affected eye
  3. Wearing an eye patch to protect the eye
  4. Avoiding contact lenses until the ulcer has healed
  5. Getting plenty of rest and avoiding strenuous activities

If you are experiencing symptoms of marginal corneal ulcer, it is important to seek medical attention right away. With prompt and appropriate treatment, most people are able to recover from this condition and avoid long-term vision problems.
