Usually associated with conjunctivitis, eye discharge is the excretion of any substance other than tears. This common sign may occur in one or both eyes, producing scant to copious discharge. The discharge may be purulent, frothy, mucoid, cheesy, serous, clear, or stringy and white. Sometimes, the discharge can be expressed by applying pressure to the tear sac, punctum, meibomian glands, or canaliculus.

Eye discharge is common with inflammatory and infectious eye disorders, but it may also occur with certain systemic disorders. (See Sources of eye discharge.) Because this sign may accompany a disorder that threatens vision, it must be assessed and treated immediately.

HISTORY:
Ask the patient when the discharge began and its frequency. Does it occur at certain times of the day or in connection with certain activities?
If the patient complains of pain, ask him to show you its exact location and to describe its character. Is the pain dull, continuous, sharp, or stabbing?
Ask the patient if his eyes itch or burn. Do they tear excessively? Are they sensitive to light? Does it feel like there's something in them?

Sources of eye discharge
Eye discharge can come from the tear sac, punctum, meibomian glands, or canaliculi. If the patient reports discharge that isn't immediately apparent, you can express a sample by pressing your fingertip lightly over these structures. Then characterize the discharge, and note its source.

PHYSICAL ASSESSMENT:
Take the patient's vital signs.
Carefully inspect the eye discharge. Note its amount, consistency, and color.
Test visual acuity, with and without correction.
Examine external eye structures, beginning with the unaffected eye to prevent cross-contamination. Observe them for eyelid edema, entropion, crusts, lesions, and trichiasis. Ask the patient to blink as you watch for impaired lid movement.
If the eyes seem to bulge, measure them with an exophthalmometer.
Test the six cardinal fields of gaze.
Examine the patient for conjunctival injection and follicles and for corneal cloudiness or white lesions.

SPECIAL CONSIDERATIONS:
Apply warm soaks to soften crusts on eyelids and lashes, then gently wipe the eyes with soft gauze. Carefully dispose of all used dressings, tissues, and cotton swabs to prevent the spread of infection.

PEDIATRIC POINTERS:
In infants, prophylactic eye medication (silver nitrate) may cause eye irritation and discharge.
In children, eye discharge usually results from eye trauma, an eye infection, or an upper respiratory tract infection.

PATIENT COUNSELING:
Inform the patient that bacterial and viral conjunctivitis are contagious. If the patient has bacterial conjunctivitis, advise him to avoid contact with other people until 24 hours after receiving antibiotic treatment. Also tell him to avoid sharing towels, pillows, or cosmetic eye products and to stop wearing contact lenses until conjunctivitis resolves.
If the patient has allergic conjunctivitis, inform him that the inflammation that accompanies this form of conjunctivitis isn't contagious.
