corneal ulceration

In rare cases, a sore may develop on the white of the eye (corneal ulceration).

The most common complication is corneal ulceration, frequently in association with S. pneumoniae.

There have been at least two cases where corneal ulceration was caused by canine herpesvirus.

In fact, your risk of corneal ulcerations increases 10-fold when using extended-wear soft contact lenses.

Corneal ulceration is a very common disease of the equine eye and can have sight-threatening consequences.

Ingrown eyelashes will rub the eye causing extensive corneal ulcerations.

Bacterial infection leads to corneal ulceration, perforation of cornea, and total blindness.

Diagnosis of FVR is usually by clinical signs, especially corneal ulceration.

About 3-5% have severe disease with intense pain, and sight-threatening corneal ulceration or compression of the optic nerve.

If untreated, it can lead to corneal ulceration and ultimately to blindness as a result of corneal damage.

Viral keratitis causes corneal ulceration.

A tick attached to the side of the face may cause loss of blink reflex, corneal ulceration and an ocular discharge.

Symptoms in children include extreme UV sensitivity, excessive freckling, multiple skin cancers and corneal ulcerations.

Bullous keratopathy (blisters in the cornea) may also form, leading to nonhealing and recurrent corneal ulceration.

Collagen vascular disease (e.g., corneal ulceration or melting)

Other complications include "toxic reaction, iridocyclitis, persistent corneal epithelial defects, and corneal ulceration."

Untreated cases may develop corneal ulceration, which may perforate resulting in corneal opacification and Staphyloma formation.

Viral corneal ulceration caused by herpes virus may respond to antivirals like topical acyclovir ointment instilled at least five times a day.

Blindness resulting from corneal ulceration and scarring, and limb deformities due to arthritis and osteomyelitis are less common complications, seen in about 2-5% of cases.

Steroid containing medications should not be used for bacterial infections, as they may exacerbate the disease and lead to severe corneal ulceration and corneal perforation.

Some other dermatological symptoms that are sometimes seen but less common include hair loss, parotitis and other dental abnormalities, corneal ulceration, and focal degeneration of the macula.

Central corneal ulceration is also a significant cause of monocular blindness worldwide, accounting for an estimated 850,000 cases of corneal blindness every year in the Indian subcontinent alone.

Much of the pain associated with corneal ulceration is due to the secondary uveitis and miosis, and effective relief can often be gained with topical atropine(1%), leading to mydriasis.

Those with conjunctivitis may report mild irritation or scratchiness, but never extreme pain, which is an indicator of more serious disease such as keratitis, corneal ulceration, iridocyclitis, or acute glaucoma.

There is almost invariably a secondary uveitis present with corneal ulceration, and signs of this may also be seen: miosis, corneal oedema, aqueous flare, hypopyon, IOP changes.
