Corneal sequestrum

What is a corneal sequestrum?

A corneal sequestrum is a disease of the surface of the eye (cornea). It is commonly seen in cats, and only rarely seen in dogs. The sequestrum is an accumulation of dead corneal tissue, which acts as a foreign body and causes significant discomfort.

Why does it occur?

The cause of sequestrum formation remains to be elucidated. The reason a corneal sequestrum forms is unclear, however several underlying contributing factors have been associated with its development. Contributing factors include, but are not limited to, infectious diseases, chronic irritation due to misdirected hair or foreign bodies and dry eye disease just to mention a few.

Are any breeds predisposed?

Although all breeds can be affected, Persians, Himalayans, and British Short Hair cats seem to be predisposed.

What treatment options do I have?

Corneal sequestration is generally considered a surgical condition. Whereas supportive medical treatment and correction of the underlying cause are important, only few cases make a full recovery without surgery. Several surgical techniques are available and tailored specifically to your cat`s needs, depending on the stage of disease and other contributing factors.

What happens if I do nothing?

Corneal sequestration tends to progress, causing deep corneal ulceration, which may result in the loss of vision or the eye if left untreated, not to mention the severe ocular discomfort it causes.
