23. “If wood has a sharp end and is elongated it can penetrate deep into the orbit
and the intracranial cavity through a small entry wound”

Case of penetrating orbitocranial injury caused by Wood.
Pus from the brain abscess grew Bacteroides asaccharolyticus and
small numbers of anaerobes.
Fusobacterium sp. and Leptotrichia buccalis known to be found.

Expect rare organisms like Veillonella species to grow from organic
foreign bodies like small gram-negative anaerobic diplococcus of
which little is known was discovered.

30. RADIOLOGICAL ASPECT
Plain film radiography is not useful in detecting intraorbital wooden
foreign bodies.
Standardized ophthalmic ultrasonography (combine of standardized
A-scan and B-scan) has been suggested to be used as an alternative.
Limitations:
• May not be able to evaluate the complete orbit
• Cannot detect intraorbital wood surrounded by air.

31. CT SCAN ROLE
With the use of CT, several authors were able to detect intraorbital wood.
CT also allowed detection of associated problems such as fractures
and abscesses. Wide window widths (up to 1000 HU) were proposed to
optimize visibility of intraorbital wood.
Intraorbital wooden foreign body mimics air on standard CT window
setting and MR.

32. INTRAORBITAL WOOD FOREIGN BODIES ON CT:
USE OF WIDE BONE WINDOW SETTINGS TO DISTINGUISH WOOD FROM AIR
The wide-bone window settings usually reveal the reticulated matrix of
wood, which distinguishes wood from simple gas collections.
If wood volume averages as fat density, it is difficult to identify in the orbit on
CT.
However, with strong clinical suspicion of wooden foreign bodies and
metallic foreign bodies excluded by CT, MR imaging is indicated because
of its superiority to CT in detecting dry wooden foreign bodies.

the lateral wall of the ethmoid sinus suggestive of a possible collection of pus.

35. Retrospective, non-comparative case series.
Nineteen patients (15 males, 4 females) with penetrating orbital injuries
due to organic foreign bodies.
Time of presentation: few hours to 9 months.
Most common injury site superior orbit in 11 (57.9%) patients leading to:
• abnormal extraocular motility (84.2%)
• proptosis (68.4%)
• upper lid ptosis (47.4%)
Associated pathologies also included:
• acute cellulitis in 11
• orbitocutaneous fistula in 5
• osteomyelitis in 2 patients.
Preoperative CT and MRI identified the foreign bodies in 42% and 57% of
the patients, respectively.
The vision improved shortly after treatment
The long-term complications - extraocular muscle and eyelid motility
problems and periorbital scarring.

36. TAKE HOME MESSAGE
Early clinical signs suggesting a foreign body in the orbit:
• may be displacement of the globe
• persisting inflammation
• limitation of ocular movement with diplopia.
(Macrae, 1979)
Wood has a density similar to air and fat and can be difficult to
distinguish from soft tissue in both a plain X-ray film and a computed
tomogram.
(Green et al., 1990; Macrae, 1979;Mutlukan et al., 1991; Specht et al., 1992)
Magnetic resonance imaging is a better method of investigation in
cases of a suspected organic intraorbital foreign body.
(Green et al., 1990; Specht et al., 1992)

40. PANTOEA AGGLOMERANS
Gram-negative bacterium that belongs to the family Enterobacteriaceae.
Formerly called Enterobacter agglomerans
Known to be an opportunistic pathogen in the immunocompromised.
Commonly isolated from plant surfaces, seeds, fruit (ex. - mandarin
oranges), and animal or human feces.
It is difficult to differentiate easily from other members of this family,
such as, Enterobacter, Klebsiella, and Serratia species.
41. CLOSTRIDIUM PERFRINGENS
Clostridium perfringens (Welchii), a gram-positive anaerobic bacillus, may cause
gas gangrene following penetrating wounds.
Reported cases of C. perfringens endophthalmitis to more than sixty nine.
The Presentation:
• rapid development of a fulminating panophthalmitis
• severe pain
• early rise of ocular tension
• the appearance of blood or of a thin coffee-colored discharge
• the eventual formation of gas bubbles in the anterior chamber
• the rapid development of total amaurosis
The patient may be managed successfully by early therapeutic vitrectomy and
intravitreal and systemic antibiotic therapy.
