What causes bullous keratopathy in cats?
The etiology and pathogenesis of feline bullous keratopathy is unknown. In published reports, tests for feline immunodeficiency virus, feline leukemia virus, feline infectious peritonitis virus, feline herpesvirus, aerobic bacteria, Mycoplasma spp., Chlamydia spp., and fungi were negative (5).
How is bullous keratopathy treated?
Bullous keratopathy is treated by an ophthalmologist (a medical doctor who specializes in the evaluation and treatment—surgical and nonsurgical—of eye disorders). Salty eye drops (hypertonic saline) and salty ointments (hypertonic sodium chloride) are used to draw the excess fluid from the cornea.
Can bullous keratopathy be cured?
No preventive surgery can be performed on people with the congenital disease, although in recent years a lot of work has been done on learning about the function of the corneal endothelium and developing pharmacological treatments to improve its repair mechanisms.
How is bullous keratopathy diagnosed?
Doctors diagnose bullous keratopathy based on the appearance of the person’s cornea. Treatment can include eye drops to draw the excess fluid from the cornea, drugs to lower pressure in the eye, and corneal transplantation.
How do you get hyphema?
A hyphema is most often caused by blunt trauma to the eye. In children and adolescents the most common cause is from sports or recreational activities. It can also occur as a result of surgery inside the eye or an abnormality of blood vessels inside the eye.
How long does corneal edema take to heal?
Corneal edema can be transient and resolve itself after a few weeks or months, without treatment.
How long does a cloudy cornea take to heal?
Minor corneal abrasions heal quickly, usually within two days. More serious wounds take longer to heal and can cause irritation, pain, tearing, and redness. If the cornea becomes deeply scarred it can cause vision problems.
What causes corneal hydrops?
Corneal hydrops is caused by split-ting of Descemet’s membrane, leading to an influx of aqueous into the corneal stroma with resultant edema and haze. Depending on the patient and the extent of the tear, corneal edema and pain can range from relatively asymptomatic to severe with visual impairment.
Can Keratomalacia cause blindness?
If Keratomalacia is not treated, the softening of your corneas can lead to infection, rupture, and tissue changes that may result in blindness.
How do you treat hyphema in cats?
Hyphema, or blood in the anterior chamber of the eye, is a common condition among cats….The common approaches to treatment are:
- Use of corticosteroids as eye drops or ointment to cure inflammation arising out of the bleeding.
- Atropine eye drops to dilate the pupil, which minimizes sticking between the lens and the iris.
What is acute bullous keratopathy in cats?
Acute bullous keratopathy is an uncommon rapidly progressive corneal disease, which is usually seen in young adult cats (1). The condition is manifested with edema (bulla) (1,2), which can range from a few millimeters in diameter to the complete cornea (3). Several small vesicles may coalesce to form a larger bulla (4).
How is bullbullous keratopathy diagnosed and treated?
Bullous keratopathy is diagnosed on the basis of clinical findings. Treatment comprises the stabilization of the metalloprotease enzymes that mediate this process. Appropriate topical therapeutic agents include serum (fresh or frozen), tetracyclines, EDTA solution, and/or N-acetyl cysteine.
Is cyclosporine administration a risk factor for bullous keratopathy in cats?
Conclusions: Systemic cyclosporine administration appears to be a risk factor for development of ABK in the population of cats studied.

What is the prognosis of bullous keratopathy in dogs?
The prognosis for bullous keratopathy with surgical treatment is good (4). Acknowledgments The author thanks Drs. Lynne Sandmeyer and Bruce Grahn of the Western College of Veterinary Medicine Ophthalmology Department for their support and assistance. CVJ Footnotes
