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 results from the obstruction of the eyelid oil gland. The blockage of the gland's duct at the eyelid margin results in release of the contents of the gland into the surrounding eyelid soft tissue. For the first few days, a chalazion can cause severe discomfort. Occasionally, chalazia become infected.
