›NSAID use avoided in later pregnancy per obstetric guidance
›Imaging considerations
›CT orbits when intraocular foreign body concern
›Maternal vision threat prioritization
›Shielding per radiology protocol
›MRI avoidance if metallic foreign body possible

›Delirium risk in sensitive patients
›NSAIDs
›Renal function consideration
›GI bleed risk consideration
Pediatrics
›Exam challenges
›Limited cooperation
›Early analgesia strategy
›Child life support when available
›Lid eversion difficulty
›Missed subtarsal foreign body risk
›Consider ophthalmology if exam incomplete
›Sedation considerations
›If removal needed and uncooperative

›Safeguarding escalation per policy
›Document findings carefully
10Background/b30
Epidemiology
›Frequency and settings
›Common ED presentation in occupational settings
›Metal grinding and drilling
›Lack of eye protection association
›Material patterns
›Metallic particles common in work injuries
›Organic material common in outdoor exposures
Pathophysiology
›Tissue response by location
›Conjunctival foreign body
›Mechanical irritation and inflammation
›Trapping in fornices and under lids
›Corneal foreign body
›Epithelial defect and nociceptor activation
›Infection risk from epithelial breach
›Metallic rust ring
›Oxidation reaction
›Corneal staining and inflammation
›Intraocular foreign body
›Penetration with entrance wound
›Endophthalmitis risk from contamination
Therapeutic Considerations
›Aftercare principles
›Antibiotic prophylaxis rationale
›Superinfection prevention in epithelial defects
›Higher risk with contact lens use
›Cycloplegia rationale
›Ciliary spasm reduction
›Photophobia relief
›Avoid outpatient topical anesthetics
›Corneal toxicity and delayed healing risk
›Masking of worsening symptoms risk
