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.
Meibomitis predisposes to chalazion formation. Meibomitis causes blockage of the meibomian orifices and clogging of the glands with secretions. This result in swellings in the eyelid called chalazion and hardening of secretions with time. Chalazion is a noninfective condition. However, it can become infected and acutely inflamed, causing a tense, warm lid swelling called hordeolum internum.
