T15-T19: Effects of foreign body entering through natural orifice
T15: Foreign body on external eye
The group of conditions identified as "Foreign body on the external eye" involves the presence of an object that does not naturally belong on the surface of the eye. The foreign bodies that may come into contact with the eye's external structures can range from a piece of dust, pollen, metal particles, to an insect. These conditions typically occur as the result of an accident or an unexpected event, such as wind blowing a particle into the eye, or activities where protective eye wear is not used, like metalwork. Common symptoms can include a sensation of discomfort or a gritty feeling, excessive blinking, watering of the eye, redness, and sometimes blurred vision if the foreign body is central. If not removed in a timely manner, it could potentially lead to infection or tissue damage. This group of conditions primarily affects the ocular system, with the potential for disease progression to other parts of the ocular system if not resolved promptly.
