Mild, nonspecific or seborrheic varieties may simply require warm soaks and daily lid hygiene. The medical term for pink eye is conjunctivitis. Redness or itching of the eye, blurred vision, sensitivity to light, and a gritty sensation in the eyes are all indications that conjunctivitis might be present. Thick yellow secretions may form a crust during the night, making the eye stick shut in the morning. The infection is caused by bacteria or virus and is very contagious.
Allergies can also cause conjunctivitis.
Depending upon the cause, treatments can vary. Hot or cold compresses or medicated eye drops or gels usually are the recommended course of treatment. A cyst is caused when an oil-producing gland in the eyelid becomes blocked and in some cases, infected. There are times when a cyst can enlarge to the point that vision is affected. And sometimes a cyst will remain small and disappear on its own without the need for medical treatment.
