What is a Corneal Ulcer?
A corneal ulcer is an open sore on the clear front part of your eye, called the cornea. This part helps you see clearly. When an ulcer forms, it can cause pain, redness, and even vision loss. Because the cornea protects your eye, any damage here can be serious. Early care is important to prevent lasting problems. According to the World Health Organization, corneal ulcers are a leading cause of vision loss worldwide. If you notice any early signs of corneal ulcer, you should seek help quickly.

This tool helps them see the cornea in detail. Sometimes, doctors use a dye to highlight the ulcer. In some cases, they may take a small sample from the ulcer to find out what is causing it. This helps them choose the right treatment for corneal ulcer.

If a virus is the cause, antiviral drops may be used. Sometimes, antifungal drops are needed. In addition, doctors may give pain relief drops or ointments. Here are some common treatments:
