KGO Radio talk show host Ronn Owens discusses battle with Parkinson's disease. One of the Bay Area's best-known radio hosts recently revealed he has Parkinson's disease. The entire interview airs Sunday at 10 a.m. on ABC7.
A chalazion is sometimes the aftereffect of a sty. It is less tender but lasts longer. Natural oils from the eyelid's oil glands must drain through ducts out to the eyelashes. If debris blocks this normal drainage, it may cause a sty or chalazion. Sometimes, this debris accumulates because of a condition called blepharitis, a long-standing inflammation of the edges of the eyelids, with redness, thickening and scales and crusts.
A chalazion is generally not an infection. A chalazion often starts out as a very small red, tender, swollen area of the eyelid. In a few days, it may change to a painless slow-growing lump the size of a pea. A chalazion is often confused with a stye (or hordeolum), which is an infection of an oil gland in the eyelid. A stye produces a red, swollen, painful lump on the edge or the inside of the eyelid and usually occurs closer to the surface of the eyelid than chalazia.
