Sticky eyes in the elderly are commonly caused by increased secretion due to conjunctivitis, dysfunction of the levator glands, and chronic dacryocystitis.
1. Conjunctivitis, caused by infection of the conjunctiva by exogenous pathogens such as bacteria or viruses, or by conjunctival metaplasia, can lead to an increase in secretions, and the eyes of the elderly may become sticky.
2. Dysfunction of the levator glands can lead to blockage of the opening of the levator plate with grease or lipid plugs, which affects the quality of the tear film, and the eyes of the elderly may become sticky.
3. Tear fluid accumulates in the lacrimal sac due to long-term blockage of the tear duct, and chronic dacryocystitis may occur due to bacterial infection, which may result in purulent secretions spilling out from the tear duct, leading to mucousy eyes in the elderly.
It is recommended that patients seek timely medical attention to clarify the specific causes, and treatment under the guidance of the doctor.
