What is corneal descemetocele?
What is corneal descemetocele?
A corneal descemetocele, the anterior herniation of an intact Descemet membrane through an overlying stromal defect, is a rare, but serious outcome of progressive corneal ulceration and mandates urgent intervention owing to the imminent risk of perforation.
What does descemetocele look like?
The eye will have a grey, gelatinous appearance on the surface, and the patient typically holds the eye fully closed. A descemetocele is an ulcer that’s so deep it goes through the stroma to Descemet’s membrane. It will not pick up central stain with fluorescein stain, and it looks like there’s a divot in the eye.
What is a descemetocele dog?
An ulcer that completely penetrates the stroma but has not perforated the endothelium is called a descemetocele. Descemetoceles are often described as “halos” or “donuts,” as the stroma on the sides of the ulcer take up stain and the deep center does not.
Do corneal perforations heal?
For small perforations, a tissue adhesive (glue) may be used to heal the hole. If your condition is non-infectious, a bandaged contact lens (BCL) can be worn to help your cornea heal. If your case is more serious, you may need to have surgery to fix the cornea and restore your vision.
Can a descemetocele heal?

If the clear aqueous humor from the eye runs through the yellow stain, the patient tests positive for corneal perforation.
How do you fix a perforated cornea?
Although medical therapy is a useful adjunct, a surgical approach is required for most corneal perforations. Depending on the size and location of the corneal perforation, treatment options include gluing, amniotic membrane transplantation, and corneal transplantation.
What happens if my dogs eye ulcer doesn’t heal?
If left untreated they can persist for many months causing continuous irritation. In some cases the eye may develop a granulation tissue reaction, in which the surface of the eye becomes reddened and inflamed- this can lead to reduced vision.
