How can you tell the difference between a corneal ulcer and an abrasion?

A corneal abrasion is a scrape of the top layer, the epithelium, but does not go through Bowman’s layer underneath this. A corneal ulcer is an open sore/erosion (from inflammation or infection) that goes through Bowman’s layer into the deeper layers of the cornea.

Can a corneal ulcer burst?

The cornea is the clear window in the front of the eye (see picture to right). A perforated corneal ulcer usually occurs when the infection causes the cornea to thin. This may lead to a hole or rupture in the cornea, which damages the cornea and may seriously impact your vision.
