![]() Dry eyes also cause other symptoms like blurry vision, foreign body sensation, and red, bloodshot eyes. Dry eye is a chronic condition that causes the surface of the eyes to become inflamed and irritated. Dry Eyes. Dry eye syndrome occurs when patients don’t produce enough tears or meibum.Most often, chronic dry eyes cause blepharitis and MGD. These are severe, chronic conditions that must be diagnosed and treated by a doctor. A second condition called Meibomian Gland Dysfunction (MGD) shares these symptoms but also causes foamy discharge, yellow or green pus, and more substantial crusting along the eyelids. It can cause either, or both, inflammation of the hair follicles along the lash line and abnormal oil production. Blepharitis and MGD. Blepharitis is a chronic disorder that affects patients’ eyelids.Several underlying conditions cause excess rheum production, so pay attention to symptoms and write them down if necessary to tell the doctor exactly what’s happening. It’s best to visit an eye doctor as soon as possible. If it’s becoming more plentiful, changing in color, or becoming harder or less watery, there may be something wrong. The key to telling the difference between normal eye discharge and unhealthy crust is to compare the amount, color, and consistency of the eye discharge to previous days. And can become so severe that it makes people feel like their eyes are glued shut in the morning.Įye Discharge May Have a Medical Cause that Requires Treatment It may also appear at the edge of the eyelids instead of the corners of the eyes. ![]() Unhealthy eye discharge is crusty, more plentiful, and maybe green or darker yellow. However, it can harden on contact with the air. Healthy meibum is yellow and watery while it’s still beneath the eyelids. It’s essential to know the difference between healthy rheum production and potential symptoms of underlying diseases. That’s what causes it to collect in the corners of the eyes and sometimes dry out before waking. Since people close their eyes when they sleep, there’s no way for the tear film to wash the meibum away (1). Meibum keeps the eyes lubricated between blinks while people are awake. This helps to explain a second term for rheum: meibum. ![]() This watery mucus is produced by the conjunctiva, the thin, transparent membrane that covers the inner surface of the eyelids and the front of the eye. Rheum is a function of the eye’s tear film. In healthy people, it’s usually cream-colored and does not build up in excessive quantities, even at night. Rheum can be wet and sticky or hard and crusty. People don’t blink at night, though, so rheum builds up and starts to harden, usually beginning in the corner of the eyes then moving along the lash line. Medically, it’s known as “rheum.” This discharge serves a protective function when it’s produced in small amounts because it removes potentially harmful debris from the eye’s surface and tear ducts.ĭuring the day, rheum gets washed away when people blink.
