Summary
Retained intraorbital wooden foreign bodies can be missed on CT scans. Early suspicion and MRI are crucial for diagnosing these challenging orbital injuries.
Area of Science:
- Ophthalmology
- Medical Imaging
- Emergency Medicine
Background:
- Intraorbital organic foreign bodies present diagnostic and management difficulties for ophthalmologists.
- A high index of suspicion is necessary for orbital foreign bodies in patients with eyelid and orbital injuries.
Observation:
- A 10-year-old boy with symptoms of orbital cellulitis had a retained intraorbital wooden foreign body initially undetected by CT.
- The wooden foreign body spontaneously extruded two days later, leading to symptom resolution.
Findings:
- Wood's density similar to soft tissue makes it challenging to detect on X-rays and CT scans.
- Initial CT scans failed to identify the intraorbital wooden foreign body.
Implications:
- Clinicians must consider intraorbital foreign bodies in all periorbital trauma cases.
- Thorough history and examination are vital; MRI is preferred for suspected wooden foreign bodies.

01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
