Clinical manifestations of dry eye
Dry eyes often involve both eyes, and patients usually feel eye fatigue, foreign body sensation, dryness, and some patients also have symptoms such as eye burning, acid swelling, eye redness, eye pain, photophobia and so on. At the early stage, dry eye only mildly affects vision, and if the disease continues to progress, it can develop into corneal injury. At this time, patients often present with eye pain significantly aggravated and unbearable. In the late stage, corneal ulcers, perforations or secondary infections may occur, and scarring may also form, seriously affecting the patient's vision.
