FIGURE 2. CHALAZION. Hordeola and chalazia are two common causes of the red, swollen eyelid encountered in the Emergency Department. They can be readily distinguished with a careful history and physical exam. - Hordeolum: painful, acutely inflamed eyelid gland. Often colloquially called a stye. - Chalazion: non-painful, sterile, granulomatous, chronic inflammation of an eyelid gland. #Clinical #Ophthalmology #Photo #Chalazion
