Patients feel redness and eye pain, typically the patient feels that “sand” has entered the eye and the eye is painful, clinically known as foreign body sensation, which is actually a manifestation of ocular surface inflammation. This is followed by redness and swelling of the eyelids, fear of light, tearing, and when waking up in the morning, the eyelids are often stuck with secretions and cannot be easily opened. Severe cases may be accompanied by systemic symptoms such as headache, fever, fatigue, and swollen lymph nodes in front of the ear. Some patients form a grayish-white pseudomembrane on the surface of the eye, also known as pseudomembranous conjunctivitis. Generally speaking, the onset of the disease is 3 to 4 days to reach the climax, given the correct treatment, the disease then gradually reduced, about 2-3 weeks most can be cured.
