Presentation

History

Patients may give a history of recent exposure to an individual with red eye at home, school, or work, or they may have a history of recent symptoms of an upper respiratory tract infection.

PCF is characterized by its associated systemic manifestations. Patients experience a sudden or gradual onset of fever ranging from 100-104°F, lasting up to 10 days. Myalgia, malaise, and GI disturbances frequently are associated with the fever. The pharyngitis may be mild or quite painful.

Initial symptoms of conjunctivitis range from slight itching and burning to marked irritation and tearing, but little photophobia. Swelling of the lids may occur within 48 hours.

Signs of disease include epiphora, conjunctival hyperemia and chemosis, subconjunctival hemorrhage, follicular or mild papillary conjunctival reaction, and eyelid edema.

Mild crusting of the lids and discharge may occur; if present, it usually is serous.

PCF most frequently is bilateral, with one eye typically having onset 1-3 days prior to the second eye. With bilateral disease, the first eye generally is affected more severely.

Physical

On general examination, look for a reddened posterior oropharynx covered with glassy follicles. Nontender cervical lymphadenopathy and tender, enlarged preauricular adenopathy may be present.

On ophthalmic examination, the conjunctivitis presents initially as a diffuse hyperemia that is generally more pronounced in the lower fornix but extends throughout the palpebral mucosa and onto the bulbar conjunctiva. It may be sufficiently boggy to give a slightly gelatinous appearance to the tissue.

The lower lid may be tender to palpation and ecchymotic, giving the appearance of recent ocular trauma. Conjunctival membranes and pseudomembranes are infrequent but may be present.
