Ocular Trauma — MCQs

Q: The most toxic intraocular foreign body is a particle of:

Copper. ***Copper*** - **Copper** is considered the most toxic intraocular foreign body due to its rapid and severe inflammatory reaction, leading to **chalcosis oculi**. - This reaction can cause significant damage to ocular structures, such as the retina and optic nerve, resulting in **vision loss**. *Iron* - **Iron** foreign bodies cause **siderosis oculi**, a slower but progressive degeneration of ocular tissues due to iron deposition. - While damaging, **siderosis** is generally less acutely destructive than chalcosis oculi caused by copper. *Tantalum* - **Tantalum** is a relatively **inert** material and generally causes minimal to no inflammatory reaction when retained intraocularly. - It is often used in medical implants due to its **biocompatibility**. *Aluminium* - **Aluminium** is largely considered an **inert** intraocular foreign body, similar to tantalum. - It typically causes little to no inflammatory response and is less likely to lead to significant ocular damage.
