12.
A farmer has a small piece of plant material removed from the cornea. The following day, pain and photophobia have increased and a focal corneal infiltrate has appeared around the epithelial defect. Which complication should be suspected?
13.
A patient with sympathetic ophthalmia initially improves with systemic corticosteroids but develops recurrent bilateral inflammation when treatment is reduced. Which therapeutic principle is most appropriate for persistent disease?
14.
A patient with suspected penetrating ocular trauma has an irregular peaked pupil. What does this finding most strongly suggest?
15.
A 24-year-old man sustains an ocular injury while hammering metal. Examination suggests a full-thickness corneal wound. Which category best describes this injury?
16.
A patient presents after blunt trauma to the eye. The globe wall has ruptured at a weak point away from the site of impact. Which type of injury is most likely?
17.
A patient presents after a high-velocity metal-on-metal injury. An intraocular metallic fragment is suspected. Which investigation is most appropriate initially?
18.
A patient has persistent central visual impairment several weeks after blunt ocular trauma. The anterior segment has recovered, but fundus examination shows traumatic disruption of the choroid involving the macular region. Which injury best accounts for the persistent reduction in central vision?
19.
A patient has permanent reduction in vision after ocular trauma but retains useful residual vision. Which intervention best represents low-vision rehabilitation?
20.
Six weeks after a penetrating injury to his left eye, a patient develops bilateral photophobia, visual reduction, granulomatous intraocular inflammation and exudative retinal changes. Once the diagnosis is established, which systemic treatment is most appropriate for controlling the underlying inflammatory process?
21.
A 38-year-old mechanic has permanent loss of useful vision in one eye after severe trauma. The fellow eye has normal visual acuity, and he wishes to return to workshop duties. Which rehabilitation measure is most important for preventing further disabling visual loss?
22.
Several weeks after penetrating injury to one eye, a patient develops photophobia, reduced vision and granulomatous uveitis in both eyes. Which diagnosis is most likely?
23.
A superficial corneal foreign body is removed successfully under topical anesthesia. The patient asks for the same anesthetic drops to use whenever pain recurs at home. Which consequence best explains why repeated outpatient use should be avoided?
24.
A 35-year-old agricultural worker undergoes repair of a contaminated penetrating ocular injury. Two days later he develops increasing ocular pain, rapidly worsening vision and marked intraocular inflammation. Which complication is the greatest concern?
25.
A cook sustains a hot-oil splash to the face. After cooling and cleaning, the eyelids are swollen and the patient complains of pain and photophobia. Which examination technique is most useful for detecting associated corneal epithelial loss?
26.
A 29-year-old man presents with a full-thickness corneal laceration and prolapsed iris following injury with broken glass. After the eye has been protected and the patient stabilized, which principle represents the definitive management of the primary injury?
27.
A patient arrives after an alkali splash to the eye. A colleague suggests applying a dilute acidic solution to chemically neutralize the alkali. Which management principle is most appropriate?
28.
A 27-year-old man sustains an injury from the edge of a metal sheet. Slit-lamp examination shows a partial-thickness scleral wound that does not extend through the complete eyewall. The anterior chamber is formed and no aqueous leakage is demonstrated. How should this globe injury be classified?
29.
A 30-year-old worker develops foreign-body sensation and watering after dust enters his eye. Examination shows vertical linear corneal abrasions but no foreign body on the exposed cornea. What is the most appropriate next examination step?
30.
A metal fragment enters the eye through the cornea and remains within the vitreous cavity. How should this injury be classified?
31.
A patient develops secondary glaucoma several months after significant blunt ocular trauma. Which previous traumatic change most likely explains this complication?
32.
Following successful repair of ocular trauma, a patient has useful visual potential but develops irregular corneal optics and a large refractive difference between the two eyes. Spectacles provide unsatisfactory visual quality. Which rehabilitation option is most appropriate to consider?
33.
A welder develops bilateral severe eye pain, photophobia and watering several hours after working without protective goggles. Fluorescein shows diffuse superficial punctate corneal staining. Which diagnosis is most likely?
