Laboratory Studies

No laboratory studies are indicated for hordeolum.

Colonization with noninvasive bacteria is common, and bacterial cultures of material from the area generally do not correlate with clinical improvement.

Conjunctival bacteria culture results are positive in as many as 70% of asymptomatic persons with a hordeolum. S aureus is the most likely organism discovered, but cultures of the eyelid are more likely to obtain Staphylococcus epidermidis. For this reason, eye cultures are of little clinical value.

Blood tests are of no value in a simple hordeolum, but generalized eyelid cellulitis requires a more complete evaluation. If the infection is not well localized, a CBC and blood culture are required, and ophthalmologic consultation is indicated.
