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.
Causes: A chalazion is a pimple-like bump on the eyelid that is caused by oil glands in the eyelid being blocked. A chalazion may appear after a sty has resolved. The inflammation from the sty leads to blockage of the oil gland which results in a firm nodule that is not tender to touch.
