Corneal pannus means the growth of fine blood vessels onto the clear corneal surface. The treatment depends on the cause. For instance, a common cause of corneal pannus is contact lens wear, particularly if the contacts are ill-fitting.

Does corneal pannus go away?

Pannus is a chronic progressive corneal disorder that cannot be cured. The therapeutic goal should be control and sometimes regression of the lesions so that blindness can be avoided.

How do you treat corneal pannus?

Deep stromal neovascularization develops insidiously, usually in an already compromised cornea (e.g. keratoconus), and may also progress in the absence of acute symptoms. A pannus is a thick plexus of vessels typically observed at the superior limbus.

Can you reverse corneal neovascularization?

In normal individuals, the cornea is avascular. Chronic local hypoxia (such as that occurring with overuse of contact lenses) or inflammation may lead to peripheral corneal vascularization, or pannus. Pannus may also develop in diseases of the corneal stem cells, such as aniridia. It is often resolved by peritomy.

Where is pannus located?

Panniculus, often incorrectly referred to as pannus, is a medical term describing a dense layer of fatty tissue, consisting of excess subcutaneous fat within the lower abdominal region.

Does pannus cause blindness?

Pannus, also known as Chronic Superficial Keratitis (CSK), is an autoimmune disease that affects the cornea (the clear) part of the eye and, left untreated, can eventually scar the eye so badly it can cause serious vision impairment or blindness.
