Ocular foreign body (microgravity)
Background
- Ocular foreign bodies are a high-risk chief complaint because of short and long-term threats to vision loss and loss of crew function.
- Risk of ocular injury from foreign body in space and microgravity may be higher than on earth due to unintended airborne particulate matter remains suspended and may travel along existing air currents.
- Second most common ocular complaint (behind irritation) with estimated prevalence of 11.11% - 35.56% of astronauts on International Space Station and Shuttle. [1]
