Chalazion and Hordeolum (Stye)
Symptoms and Signs of Chalazion and Hordeolum
Chalazia and hordeola each cause eyelid redness, swelling, and pain. Initially the eyelid is diffusely swollen. Occasionally the eyelid can be massively swollen, shutting the eye completely. After 1 or 2 days, a chalazion localizes to the body of the eyelid. Typically, a small nontender nodule or lump develops. A chalazion usually drains through the inner surface of the eyelid or is absorbed spontaneously over 2 to 8 weeks; rarely, it persists longer. Depending on its size and location, a chalazion may indent the cornea, resulting in slightly blurred vision. After 1 to 2 days, an external hordeolum localizes to the eyelid margin. There may be tearing, photophobia, and a foreign body sensation. Typically, a small yellowish pustule develops at the base of an eyelash, surrounded by hyperemia, induration, and diffuse edema. Within 2 to 4 days, the lesion ruptures and discharges material (often pus), thereby relieving pain and resolving the lesion. Symptoms of an internal hordeolum are the same as those of a chalazion, with pain, redness, and edema localized to the posterior tarsal conjunctival surface. Inflammation may be severe, sometimes with fever or chills. Inspection of the tarsal conjunctivae shows a small elevation or yellow area at the site of the affected gland. Later, an abscess forms. Spontaneous rupture is rare; however, when it does occur, it usually occurs on the conjunctival side of the eyelid and sometimes erupts through the skin side. Recurrence is common.
