Stye (hordeolum) Definition: Acute, purulent inflammation of the glands or eyelash follicles of the eyelid. The term stye generally refers to external hordeola, those arising from eyelash follicles or tear glands at the lid margin (as opposed to meibomian glands under the conjunctival side of the eyelid, which is where internal hordeola and chalazia tend to occur). #Clinical #Ophthalmology #Hordeolum #Stye
