Chalazion and Stye (Hordeolum)
Symptoms of Chalazion and Stye
At first, a chalazion may cause a swollen eyelid, mild pain, and irritation. However, these symptoms disappear after a few days, leaving a round, painless swelling in the eyelid that grows slowly for the first week. Occasionally, the swelling continues to grow and may press on the eyeball and cause slight blurring. A red or gray area may develop on the underside of the eyelid. A stye usually begins with redness, tenderness, and pain at the edge of the eyelid. Then a small, round, tender, swollen area forms. The eye may water, become sensitive to bright light, and feel as though something is in it (foreign body sensation). Usually, only a small area of the eyelid is swollen, but sometimes the entire eyelid swells. Often a tiny, yellowish spot develops at the center of the swollen area, usually at the edge of the eyelid. The stye tends to rupture after 2 to 4 days, releasing a small amount of material (often pus) and ending the problem. With an internal stye, pain and other symptoms are usually more severe than with an external stye. Pain, redness, and swelling tend to occur underneath the eyelid. Occasionally, inflammation is severe and may be accompanied by fever or chills.
