When a large corneal ulcer is staring you in the face, time is not on your side Based on these layers, there are several types of corneal ulcers: superficial, stromal, and descemetoceles The types of corneal ulcer (keratitis) are - Bacterial - scratches or abrasion with fingernail, paper cuts, makeup brushes over the cornea when left untreated can lead to an ulcer. common in extended wear contact lens wearers Fungal - injury to the cornea with any vegetative matter or improper use of steroid eye drop Causes of Corneal Ulcer People usually develop a corneal ulcer after some type of corneal trauma, which allows bacteria, viruses, fungi, or parasites to enter the cornea. This invasion causes an infection with inflammation, which worsens if left untreated. The types of infections that can lead to a corneal ulcer include Corneal ulceration is the excessive loss of cells in the outermost layer of tissue (epithelium) covering the cornea. The condition will become progressively more severe as the cell loss outpaces the generation of new epithelial cells. In an advanced case, a perforation may develop on the corneal surface, allowing drainage of the intraocular contents

Corneal ulcers are a serious problem and may result in loss of vision or blindness. Most corneal ulcers are preventable Practical relevance: Corneal ulcers in cats (ulcerative keratitis) are a common presenting complaint, and are a frequent sequela to feline herpesvirus (FHV-1) infection. In fact, it is fair to assume an FHV-1 aetiology until proven otherwise. In practice, therefore, many cases of corneal ulceration can be treated medically, but treatment can frequently be challenging, with the need to tailor. The main cause of corneal ulcers is infection. Acanthamoeba keratitis. This infection most often occurs in contact lens wearers. It is an amoebic infection and, though rare, can lead to blindness

Other types of ulcers, particularly those that are very deep sometimes require surgery. There is a specific ulcer called a SCCED (superficial chronic corneal epithelial. A corneal ulcer is deeper erosion through the entire epithelium and into the stroma. With a corneal ulcer, fluid accumulates in the stroma, giving a cloudy appearance to the eye. If the erosion goes through the epithelium and stroma to the deepest level of Descemet's membrane, a descemetocele is formed. A descemetocele is a very serious condition
The cornea is the clear, glistening membrane that makes up the surface of the eyeball.

A corneal ulcer occurs when deeper layers of the cornea are lost; these ulcers are classified as either superficial or deep. If your cat is squinting or its eyes are tearing excessively. Without surgery many of the deeper corneal ulcers require corneal vascularisation to fully heal. This will result in a lot more corneal scarring, so surgery is beneficial for two reasons: 1) the ulcers heal faster, and 2) there will be less scarring in most cases. Surgery for Deep Corneal Ulceration. Surgery is indicated Cornea allows light to go into the eye. It also acts as a protector of the eye preventing it from infiltration of various types of bacteria, virus, and fungi. Sometimes, generally due to infections, a sore forms in this layer of tissue in front of the eye. This is what is called as a Corneal Ulcer.
