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.
The gland involved in the formation of a chalazion is a modified oil gland (meibomian gland) that lies within the eyelid. These glands secrete oil into the tears. When one of these glands becomes blocked, it can increase in size and cause a visible lump. A chalazion is not a growth or tumor.
