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.
Chalazion is a cyst in the eyelid due to a blocked oil gland. They are typically in the middle of the eyelid, red, and non painful. They tend to come on gradually over a few weeks. A chalazion may occur following a stye or from hardened oils blocking the gland. The blocked gland is usually the meibomian gland but can also be the gland of Zeis. A stye and cellulitis may appear similar. A stye; however, is usually more sudden in onset, painful, and occurs at the edge of the eyelid.
