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 chronic noninfective inflammation of the sebaceous glands of the eyelid. They commonly affect the meibomian glands in the tarsal plate, resulting clinically as a painless, firm nodule of the eyelid. Marginal chalazia are caused by inflammation of the gland of Zeis located at the lid margin. They can affect both the upper and lower lids.
