outward bulging of the base of a deep ulcer of the cornea. The deep layer of the cornea (Descemet’s membrane) is elastic and relatively resistant to perforation; it therefore bulges when the overlying cornea has been destroyed. From: keratocele in Concise Medical Dictionary » How is Descemetocele treated?
Commonly available treatment options include therapeutic bandage contact lenses, tissue adhesives, amniotic membrane transplantation, corneal patch grafts, penetrating or lamellar keratoplasty, and conjunctival flaps.

Where is Descemet’s membrane?

cornea Small bloodvessels cut across near the margin of the cornea. Descemet’s membrane (or the Descemet membrane) is the basement membrane that lies between the corneal proper substance, also called stroma, and the endothelial layer of the cornea. What is corneal melt?
Corneal melting is a common prelude to the development of corneal perforation. This process occurs from conditions such as infections, sterile inflammation, or surgical/chemical injury to the cornea. 1 ,2 ,3. Collectively, these conditions are a significant cause for blindness world-wide.

Can a Descemetocele heal?

However, when a corneal ulcer or descemetocele occurs, the body will promote healing by forming a new blood supply across the surface of the cornea through a process called neovascularization. The new vessels begin at the sclera (the white part of the eye) and cross the cornea to the ulcer. Can a dogs corneal ulcer heal on its own?

What is the purpose of Descemet’s membrane?

Descemet’s membrane plays an essential role in corneal structure and homeostasis, as well as in the maintenance of the corneal transparency. Descemet’s membrane anchors the endothelium to the cornea, while simultaneously allowing the entry of nutrients and macromolecules into the corneal stroma.

What is Descemet’s folds?

Descemet folds are associated with corneal edema due to endothelial dysfunction from infections, from infiltrations, or following surgery. Descemet folds also are associated with corneal inflammation due to infections or infiltrations or following surgery.

What is neurotrophic cornea?

Neurotrophic keratopathy is a degenerative disease of the corneal epithelium resulting from impaired corneal innervation. A reduction in corneal sensitivity or complete corneal anesthesia is the hallmark of this disease and is responsible for producing epithelial keratopathy, ulceration and perforation.
