An ocular foreign body refers to any object that becomes lodged in the eye, potentially causing injury or irritation. Common examples include dust, metal shards, or wood splinters. These foreign bodies can lead to symptoms such as redness, pain, tearing, and blurred vision. Prompt medical evaluation is essential to prevent complications. Diagnosis typically involves a thorough eye examination, often using tools like a slit lamp. Treatment may include removal of the foreign body, which can be done with specialized instruments. In some cases, additional care may be necessary to address any resulting damage to the eye, such as corneal abrasions or infections.
