A hordeolum, commonly known as a stye, is typically caused by a blocked and inflamed gland or pore in the eyelid. Specifically, it is often related to an infection in the oil glands (Meibomian glands) or the hair follicles of the eyelashes. When these glands become blocked, bacteria can multiply, leading to inflammation and the formation of a painful bump on the eyelid. This condition is quite prevalent and can occur in anyone, often manifesting as redness, swelling, and tenderness in the affected area. The correct understanding of hordeolum being linked to blockage and inflammation is essential for recognizing the symptoms and understanding treatment options.
