Question: 1 / 400

What symptom might indicate the presence of a foreign object in the eye?

Increased IOP

Photophobia

Photophobia, or sensitivity to light, is a symptom that can indicate the presence of a foreign object in the eye. When an object is lodged in the eye, it can stimulate the cornea and other sensory nerve endings, leading to discomfort and an increased sensitivity to light. This is often due to the irritation and inflammation caused by the foreign body, prompting the affected individual to instinctively avoid bright light as it exacerbates their pain or discomfort.

In contrast, increased intraocular pressure (IOP) can occur for various reasons, but it is not a direct indicator of a foreign object. Trismus, which is a restricted ability to open the jaw, is generally related to dental or muscular issues rather than eye injuries. Hyphema, characterized by bleeding in the anterior chamber of the eye, can occur from trauma but is more related to blunt force injury or certain medical conditions rather than having a specific foreign body present.
