keratitis: L PREMESHWORI DEVI M.Sc NURSING 1 ST YEAR RPCON keratitis DEFINITION: Keratitis is inflammation of cornea. It is a condition in which the eye’s cornea ,the front part of the eye become inflamed. The condition is usually marked by moderate to intense pain usually involved impaired eyesight. It may cause felling of itching each time of individual blink. DEFINITION TYPES: Superficial keratitis involves the superficial layers (i.e. the epithelium) of the cornea. After healing, this form of keratitis does not generally leave a scar. Deep keratitis involves deeper layers of the cornea (i.e. The epithelium, Bowman's Membrane and often stroma), and the natural course leaves a scar upon healing that impairs vision . TYPES RISK FACTOR: Contact lenses. wearing contact lenses while swimming, wearing them longer than recommended, or using water or homemade solutions to store and clean lenses. Reduced immunity. immune system is compromised due to disease or medication is at higher risk of developing keratitis. Warm climate. warm, humid climate, risk of keratitis is increased, particularly if plant material gets into eyes. Plant material can scratch the corneal epithelium and chemicals from the plant can cause an inflammation, which may then lead to an infection. RISK FACTOR CONTD..: Corticosteroids. Use of corticosteroid eye drops to treat an eye disorder can increase risk of developing keratitis or worsen existing keratitis. Eye injury. If corneas has been damaged from an injury in the past, it may be more vulnerable to developing keratitis. CONTD.. CAUSES: Keratitis has multiple causes, one of which is an infection of a present or previous herpes simplex virus secondary to an upper respiratory infection, involving cold sores. CAUSES CAUSES: Amoebic keratitis. Amoebic infection of the cornea is the most serious corneal infection, usually affecting contact lens wearers. It is usually caused by Acanthamoeba . Bacterial keratitis. Bacterial infection of the cornea can follow from an injury or from wearing contact lenses. The bacteria involved are Staphylococcus aureus and for contact lens wearers, Pseudomonas aeruginosa. Pseudomonas aeruginosa contains enzymes that can digest the cornea. CAUSES Signs and symptoms of keratitis: Eye redness Eye pain Excess tears or other discharge from eye Difficulty opening eyelid because of pain or irritation Blurred vision Decreased vision Sensitivity to light (photophobia) A feeling that something is in eye Signs and symptoms of keratitis : DIAGNOSTIC EVALUATION: Eye exam. General examination of eye will perform . (visual acuity) Penlight exam. Examine eye using a penlight, to check pupil's reaction Slit lamp exam. detect the character and extent of keratitis, Laboratory analysis. a sample of tears or some cells from cornea for laboratory analysis to determine the cause of keratitis and to help develop a treatment DIAGNOSTIC EVALUATION MANAGEMENT: Treatment depends on the cause of the keratitis. Infectious keratitis can progress rapidly, and generally requires urgent antibacterial, antifungal, or antiviral therapy to eliminate the pathogen. Contact lens wearers are typically advised to discontinue contact lens wear (Contaminated lenses and cases should not be discarded as cultures from these can be used to identify the pathogen). MANAGEMENT TREATMENT: Antibacterial solutions include levofloxacin, gatifloxacin, moxifloxacin, ofloxacin. 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.e.g. Maxitrol (neomycin+polymyxin+dexamethasone),. Aciclovir is the mainstay of treatment for HSV keratitis and steroids should be avoided at all costs in this condition. TREATMENT Nursing management: Advice not to wear contact lens more then the recommended hours. Strict instruction should be given to maintain eye hygiene. Support while walking the patient. Advice to use medication timely Nursing management Nursing diagnosis: Acute pain related to infection Nursing interventions Assess the condition and severity of pain Provide medication according to causative organism Instruct to maintain eye hygiene Advice to avoid contact lens. Nursing diagnosis Nursing diagnosis: Risk for injury related to impaired vision Nursing interventions Assess the visual acuity of the patient Support while walking the patient Lower the level of the patient Nursing diagnosis NURSING DIAGNOSIS: Anxiety related to impaired vision Nursing interventions Assess the anxiety level of the patient Provide psychological support to the patient Provide medication Educate about the disease condition NURSING DIAGNOSIS Nursing diagnosis: Sleeping pattern disturbance related to itching Nursing intervention Assess the sleeping patter of the patient Provide cool and calm environment Restrict the visitor Nursing diagnosis reference: keratitis /basics/.../con-2003528..
