Treatment of keratitis

Psoriasis-Ltd III has great success in treating keratitis. Keep you body and eyes well hydrated, wear protective eyewear or sunglasses to protect the eyes from excessive sunlight and flying particles that could cut the eye. If you are suffering from a virus, infection or flu don't touch your eyes as this can result in the eyes becoming infected. If you wear contacts, remove them and sterilize them every day. Change your eyes makeup every three to six months to avoid bacteria and contamination. Keep your body healthy so it's less susceptible to infections with a well-balanced alkaline diet.

In some cases it may be necessary to treat the keratitis with anti-bacterial or anti-fungal eye drops. Antiviral eye drops may be needed to treat the keratitis symptoms caused by the herpes simplex type 1 and other viruses.

Psoriasis keratitis can have an unfavorable prognosis, and in extreme cases can lead to corneal opacity with blindness. Ocular psoriasis combined with Keratitis could lead to blindness.

We continually update this site to keep you informed of the latest scientific findings about ocular psoriasis and keratitis.

What is keratitis?

Keratitis is an all-inclusive term used to define an inflammation, infection or irritation of the transparent membrane or cornea that covers the colored part of the eye and the pupil of the eye. Usually, the infection occurs after the cornea has been injured or penetrated, allowing bacteria or fungi to enter and the deeper the infection, the more severe its symptoms and complications. This condition may result in severe eye pain, blurry or decreased vision, sensitivity to light, tearing of the eye, inflammation of the eyelid, and redness in the eye.

There are varying degrees of keratitis involvement: Superficial keratitis involves the top layers of the cornea. After healing, Superficial keratitis rarely results in scarring of the cornea. Deep keratitis is a term used to decribe involvement of the deeper layers of the cornea, and upon healing will result in scar tissue which may impair vision if the scarring is located on or within the visual axis of the eye. Limited success in reducing scarring has been achieved with short-term appication of topical steroid eyedrops.

Cause of Keratitis

There are multiple causes of keratitis. A scratch can leave the cornea open to infection allowing for organisms or bacteria to attack the cornea. Certain autoimmune conditions such as psoriasis, or rosacea can present an opportunity for infection to occur. Lack of moisture can result in a very dry eye, which can reduce the cornea's protective mechanisms, allowing for infections to occur. Keratitis can be the result of an infection -bacterial, viral, or fungal.

Dry eyes caused by disorders of the eyelid or diminished ability to form tears can result in keratitis. Photosensitivity caused exposure to very bright light can cause keratitis. Exposure of the eye to foreign objects that injure or become lodged in the eye can result in keratitis. Allergic sensitivity to eye makeup, dust, pollen, pollution, or other irritants such as present in Atopic eczema can result in eye eczema or keratitis development. Even vitamin A deficiency resulting from a pH imbalance may allow for conditions to promote the occurrence of keratitis.

Other risk factors that may result in keratitis include but are not limited to poor hygiene in cleansing and sterilizing contact lenses, overuse of contacts or wearing them to bed.

Any illness or medical condition that affects the body's ability to fight infection such as various types of herpes, HIV, flu, bacterial and viral infections can result in conditions making the eyes more susceptible to keratitis.

Keratitis can be further defined by the factors that result in an occurrence of the condition:

Acanthamoeba keratitis is a very painful pus-producing form of keratitis. It is an avoidable situation that often occurs from an infection resulting from the use soft or rigid contact lenses. It can be found in tap water, soil, and swimming pools.

Bacterial keratitis often results from improper care and cleaning of contact lenses or wearing soft daily-wear lenses overnight (which increases risk about 10-fold, according to some research). Contaminated eye makeup can also cause bacterial keratitis. For this reason it is advisable to replace all eye makeup every three to six months or anytime the use of it results in an infection. This type of bacterial keratitis infection is often aggressive in nature, characterized by waking up with your eyelids stuck together. One may also experience eye pain, sensitivity to light, redness, tearing, and a decrease or blurriness in vision.

Dendritic keratitisis an infection that result in an inflammation of the membrane lining the eyelid and the portion of the eyeball that comes into contact with it. It usually occurs only in one eye. Recurrent infections are characterized by a pattern of lesions that resemble the veins of a leaf. Recurrences are often caused by stress, fatigue, or bright sunlight. Repeated episodes of dendritic keratitis can cause sores, permanent scarring, and numbness of the cornea.

Disciform keratitis is the result of recurrent episodes of dendritic keratitis. Disciform keratitis gets its name from the deep, disc-shaped swelling of the cornea. It also results in inflammation of the iris and cloudiness in the eyes.

Fungal keratitis is caused an injury to the cornea in a rural or farm-like setting or in a place where plant material is present. Fungal keratitis usually affects only people with weakened immune systems due to an underlying condition and develops slowly over time.

Herpes simplex keratitis, is considered the most common cause of keratitis. The same virus that causes cold sores causes herpes simplex keratitis. Once diagnosed with the herpes simplex virus, one needs to be vigilant, because if left untreated, herpes simplex keratitis can be serious - causing vision loss, corneal scarring, chronic inflammation and glaucoma. Herpes-caused recurrences happen frequently, and may be triggered by stress, fatigue or photosensitivity. Another herpes virus that can cause keratitis is varicella zoster virus, which is associated with chickenpox and shingles, and the group of adenoviruses, which cause upper respiratory infections. It is very important not to treat herpes simplex keratitis with topical corticosteroids as they can make it much worse, possibly leading to blindness.

Interstitial keratitis or parenchymatous keratitis, is a chronic inflammation of tissue deep within the cornea. Interstitial keratitis affects both eyes and results as a complication of congenital or acquired syphilis. In cases of congenital syphilis, interstitial keratitis occurs in younger children aged two to 14. Interstitial keratitis may also occur in people with tuberculosis, leprosy, or other diseases. Interstitial keratitis is considered rare in the United States.

Marginal keratolysis also known as Peripheral ulcerative keratitis or peripheral rheumatoid ulceration is keratitis occurring as a result of rheumatoid arthritis, kidney disease that results in the development of nodules in the respiratory tract called Wegener's granulomatosis or a connective-tissue inflammation called relapsing polychondritis.

Photokeratitis or snow blindness results from excessive exposure to UV light due to bright sunlight, sun tanning lamps, or a welding arc. Snow blindness is caused by sunlight reflecting off of the snow. Photokeratitis may also occur due to the reflection of light off of the water. Photokeratitis is a painful condition and may occur up to several hours after exposure to excessive light. Photokeratitis can last one to two days.

Superficial punctate keratitis results from upper respiratory infections called adenoviruses. In superficial punctate keratitis, the main concern is the destruction of pinpoint areas in the outer layer of the cornea. Superficial punctate keratitis can affect one or both eyes.
