Does having a lot of eye discharge mean there are worms inside?

Excessive eye discharge is usually not caused by parasites inside the eye. However, in cases of demodex blepharitis, the presence of mites may be the cause. The actual situation varies from person to person. Detailed explanations are as follows:

Allergic conjunctivitis may result from exposure to allergens such as pollen or dust. Its main symptoms include itchy eyes and increased eye discharge. Therefore, excessive eye discharge is typically not due to parasites but rather may be caused by allergic conjunctivitis. When any abnormality occurs in the eyes, it is recommended to visit a hospital for a professional examination to determine the exact cause.

If a person has demodex blepharitis, excessive eye discharge could indeed indicate the presence of mites. Demodex blepharitis is usually caused by infestation with Demodex mites, which feed on keratin proteins and oils. Areas such as eyelashes and meibomian glands, which produce abundant oils, provide an ideal habitat for these mites. As a result, demodex blepharitis can lead to symptoms such as dry eyes and increased eye discharge. If diagnosed with demodex blepharitis, treatment with intense pulsed light (IPL) at a medical facility is recommended.

In daily life, it is advisable to maintain good eye hygiene and avoid rubbing the eyes with hands to prevent ocular infections caused by bacteria, fungi, or parasites.
