Question 1

A child sustains an ocular injury in which a shard of glass from a bottle penetrated the eye wall. The emergency department provider notes that the shard has remained in the eye. Which term best describes this type of injury?

A) Intraocular foreign body
B) Penetrating eye injury
C) Perforating eye injury
D) Ruptured globe injury

A

Accepted Answer

Intraocular foreign body refers to a foreign object that enters the eye and remains within the eye, but not extending past the eye wall. Penetrating eye injury, perforating eye injury, and ruptured globe injury all describe injuries that involve a full-thickness injury to the eye wall, but do not specify whether the foreign body remains in the eye or has exited the eye.

Question 2

Which protective precaution is especially important in a metal fabrication workshop?&#10;A) 2 mm polycarbonate safety glasses&#10;B) Eyewash stations&#10;C) Glasses with UVB protection&#10;D) Polycarbonate goggles

Accepted Answer

Polycarbonate goggles provide the best protection against flying debris, sparks, and other hazards that are common in metal fabrication workshops. They cover a larger surface area of the eye and are more secure than regular safety glasses. Eyewash stations are also important to have in case of an emergency, but they do not provide protection for the eyes during regular work activities. The other two options, 2 mm polycarbonate safety glasses and glasses with UVB protection, are not specific enough for the hazards present in a metal fabrication workshop.

Question 3

A patient experiences a penetrating injury to one eye caused by scissors. The provider notes a single laceration away from the iris that involves the anterior but not the posterior segment. What is the prognosis for this injury?

A) Because the posterior segment is not involved, the prognosis is good.
B) Blindness is likely with this type of eye injury.
C) Massive hemorrhage and loss of intraocular contents is likely.
D) Retinal detachment is almost certain to occur.

A

Accepted Answer

The fact that the laceration does not involve the posterior segment is a positive prognostic factor, as this area contains important structures such as the retina and optic nerve. However, long-term visual outcomes may depend on the size and location of the injury, as well as the promptness and effectiveness of treatment. Close follow-up and possible surgical intervention may be necessary to maximize visual recovery.
