The specific nature and accompanying symptoms of a yellow discharge from the eye should be clarified first. In the conjunctival sac, the yellow discharge may be caused by a bacterial infection, a sign that can occur in diseases such as keratitis and conjunctivitis. The best evidence to suggest bacterial infection is especially evident in the morning when the discharge sticks to the eye. It is usually treated with antimicrobial eye drops, which can be used more often in the acute phase to quickly relieve the inflammatory response. If it is a yellow translucent swelling around the cornea, it is usually a dermatoma, which occurs in newborns and is usually treated surgically. Patients who may infiltrate the cornea causing visual impairment in particular should be operated early to avoid amblyopia. If the yellow translucent material is visible on the medial side of both eyes, it may be a dermatofibroma, which usually does not cause significant effects on the eyes and can be operated to improve the appearance, but there is a possibility of complications of intraorbital disorders.
