How do you assess for conjunctivitis?
Eye Culture During this test, your doctor takes a sample of the cells on the inside of your eyelids with a cotton swab and sends it to a laboratory to be examined by a pathologist. A pathologist, who studies diseases under a microscope, can determine whether your conjunctivitis is caused by viruses or bacteria.
How would you describe a normal conjunctiva?
Conjunctiva: The sclera is covered by a thin transparent membrane known as the conjunctiva, which reflects back onto the underside of the eyelids. Normally, it’s invisible except for the fine blood vessels that run through it.
What is noted when assessing the conjunctiva and sclera?
In evaluating the conjunctiva and sclera, note the color of the palpebral conjunctiva (looking for unusual paleness signifying anemia), the color of the sclera (noting blueness, yellowness, redness), the vascular pattern, or the presence of nodules.
How does a nurse assess movements of the eyes?
The nurse covers one of the patient’s eyes with a card and observes the uncovered eye for movement, then removes the card and observes the just uncovered eye for movement.
What are nursing diagnosis for conjunctivitis?
Signs and Symptoms of Conjunctivitis Chemosis – swelling of the conjunctiva. Increased tear production. The feeling of a foreign body stuck in the eye, which may be accompanied by an urge to rub the affected eye. Itching, irritation, and burning sensation in the affected eye.
What are the priorities of care for the person with conjunctivitis?
Discharge Planning
- Educate patient on the disease.
- Apply cool compress.
- Take medications as prescribed.
- Encourage hand washing.
- Use artificial tears if the eye is irritated.
- Do not share personal care items.
- Keep children at home until symptoms subside.
- Wear sunglasses when going out.
What is the appearance of bulbar conjunctiva?
It is important to appreciate the differences in normal appearance across the conjunctival sac. The bulbar conjunctiva is loosely bound to the globe and it appears mainly white due to the color of the sclera beneath. Blood-filled capillaries impart a salmon pink color.
How do nurses assess eyes?
Eyes:
- Have the patient follow your pen light by moving it 12-14 inches from the patient’s face in the six cardinal fields of gaze (start in the midline) Watch for any nystagmus (involuntary movements of the eye)
- Reactive to light? Dim the lights and have the patient look at a distant object (this dilates the pupils)
How do you describe bulbar conjunctiva?
A condition in which the thin layer of tissue that covers the sclera (the white part of the eye) becomes inflamed. The cause is usually not known, but it may occur with certain inflammatory conditions, such as lupus and rheumatoid arthritis.
What is the first step when assessing a patient with an ocular complaint?
The examination
- Step 1: Visual examination. Inspection. Record the location, size and appearance of obvious injuries such as lacerations, swelling (contusions) or foreign bodies (FB).
- Step 2: Using a source of light. For the next steps, use a source of light.
What do you assess in the eye?
Inspect the eyes for symmetry of eyelids, size, contour, alignment of the eyeballs and signs of traumatic injury. Look for eyelid droop (ptosis), dysconjugate gaze, exophthalmos (protruding gaze) and sunken eyes. Ask the patient to close his eyes and note whether the eyelids completely cover the eyes.
What are the complications of conjunctivitis?
Complications include the following: punctate keratitis with subepithelial infiltrates, bacterial superinfection, conjunctival scarring and symblepharon, severe dry eye, irregular astigmatism, corneal ulceration with persistent keratoconjunctivitis, corneal scarring, and chronic infection.
What is the pathophysiology of conjunctivitis?
Conjunctivitis is defined as inflammation of bulbar and/or palpebral conjunctiva. Conjunctivitis has many etiologies, but the majority of cases can be caused by allergies or infection. Infective conjunctivitis is an infection of the conjunctiva either caused by viruses or bacteria.
What are the nursing management of conjunctivitis?
Medical Management Treatment of both viral and bacterial conjunctivitis should include patient education to decrease the rate of transmission. Bacterial conjunctivitis, while typically self-limiting, can be treated to help reduce the duration of symptoms.
What is the normal bulbar conjunctiva?
The bulbar conjunctiva is a thin, semitransparent, colorless tissue that covers the sclera up to the corneoscleral junction, the limbus. The palpebral conjunctiva, a thick, opaque, red tissue, is further divided into marginal, tarsal, and orbital zones.
How do you check for bulbar conjunctiva?
The bulbar conjunctiva is directly visible between the eyelids; the palpebral conjunctiva can only be examined by everting the upper or lower eyelid. The normal conjunctiva is smooth, shiny, and moist. The examiner should be alert to any reddening, secretion, thickening, scars, or foreign bodies. Eversion of the lower eyelid.
How is the conjunctiva examined during the physical exam?
The conjunctiva is examined by direct inspection. The bulbar conjunctiva is directly visible between the eyelids; the palpebral conjunctiva can only be examined by everting the upper or lower eyelid. The normal conjunctiva is smooth, shiny, and moist. The examiner should be alert to any reddening, secretion, thickening, scars, or foreign bodies.
What is the difference between the bulbar and palpebral conjunctiva?
The bulbar conjunctiva is directly visible between the eyelids; the palpebral conjunctiva can only be examined by everting the upper or lower eyelid. The normal conjunctiva is smooth, shiny, and moist.
What does a normal conjunctiva look like?
The normal conjunctiva is smooth, shiny, and moist. The examiner should be alert to any reddening, secretion, thickening, scars, or foreign bodies. Eversion of the lower eyelid. The patient looks up while the examiner pulls the eyelid downward close to the anterior margin (Fig. 1.7).
