| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What are the immediate steps in the initial assessment of a patient with an ocular injury? | Assess airway, breathing, and circulation (ABCs); evaluate visual acuity if possible; inspect the eye for foreign bodies, lacerations, or deformity; check for afferent pupillary defect; and look for signs of chemical injury or perforation. | Think ABCs plus eye-specific signs |
| 2 | How should a chemical eye burn be initially managed in the emergency setting? | Immediately irrigate the eye with copious amounts of sterile saline or water for at least 15-30 minutes to dilute and remove the chemical, then assess severity and refer for specialized care. | Dilution is the solution |
| 3 | What is the most critical first step in managing a suspected open globe injury? | Avoid applying pressure or any invasive procedures; shield the eye with a rigid eye shield to prevent further injury, and arrange urgent ophthalmologic consultation. | Do no harm before specialist help |
| 4 | Which clinical sign suggests an afferent pupillary defect (Marcus Gunn pupil) indicating optic nerve or severe retinal injury? | A relative afferent pupillary defect is observed when the affected eye shows decreased pupillary constriction compared to the unaffected eye during swinging flashlight test. | Swinging flashlight test |
| 5 | What are common signs of a chemical burn to the eye? | Redness, pain, tearing, blurred vision, conjunctival blanching, corneal opacity, and possible limbal ischemia; severity depends on chemical type and duration of exposure. | Chemical burns can be severe and require prompt irrigation |
| 6 | What is the recommended method for removing a foreign body from the eye in the emergency setting? | If the foreign body is superficial and visible, it can be gently removed with sterile saline or a moistened cotton swab; avoid using sharp instruments and do not attempt to remove embedded objects. | Gentle and cautious removal |
| 7 | When should you suspect a ruptured globe in an ocular injury? | Signs include a teardrop-shaped pupil, decreased visual acuity, irregular pupil, hyphema, low intraocular pressure, and extrusion of intraocular contents; immediate protective measures and urgent ophthalmology referral are essential. | High suspicion in penetrating injuries |
| 8 | What is hyphema, and how should it be managed initially? | Hyphema is blood in the anterior chamber of the eye, often from trauma; management includes elevating the head, avoiding blood thinners, protecting the eye, and urgent ophthalmologic evaluation. | Blood in the front of the eye |
| 9 | Why is it important to avoid applying pressure to an injured eye? | Pressure can worsen intraocular damage, increase the risk of globe rupture, or displace intraocular contents; always shield and avoid pressure until evaluated by a specialist. | Protect, don’t press |
| 10 | What are the signs of retinal detachment in an emergency setting? | Patients may report sudden onset of floaters, flashing lights, and a shadow or curtain over part of the visual field; urgent ophthalmologic assessment is critical to prevent permanent vision loss. | Curtain over vision |
| 11 | How does a corneal abrasion typically present, and what is the initial management? | Presentation includes sudden eye pain, tearing, foreign body sensation, and photophobia; management involves topical antibiotics, pain control, and eye protection, with urgent ophthalmology referral if necessary. | Scratch on the cornea |
| 12 | What is the purpose of a fluorescein dye test in ocular trauma? | To identify corneal epithelial defects or perforations by highlighting areas where the dye penetrates damaged tissue, aiding in diagnosis of abrasions or leaks. | Fluorescein reveals epithelial breaks |
| 13 | What are signs of a traumatic optic neuropathy, and what is the initial approach? | Signs include decreased visual acuity, a relative afferent pupillary defect, and visual field defects; initial management involves urgent ophthalmology referral, corticosteroids are controversial and should be guided by specialists. | Optic nerve injury needs prompt assessment |
| 14 | How can you distinguish between a chemical and an electrical injury to the eye? | Chemical injuries often involve burns with tissue necrosis and require irrigation; electrical injuries may cause deep tissue damage, burns, and complex trauma, often with systemic implications, requiring multidisciplinary management. | Different injury mechanisms |
| 15 | What are the indications for urgent ophthalmologic consultation after an ocular trauma? | Indications include suspected globe rupture, chemical burns, intraocular foreign bodies, retinal detachment signs, hyphema with increased intraocular pressure, or significant visual impairment. | When in doubt, consult specialists |
| 16 | What protective measure should be taken if a patient presents with a suspected intraocular foreign body? | Do not attempt to remove the foreign body; shield the eye with a rigid eye shield, keep the patient NPO if surgery is anticipated, and arrange urgent ophthalmologic evaluation. | Shield before removal |
| 17 | What is the typical presentation of a blowout fracture of the orbit? | Patients may have enophthalmos, infraorbital nerve anesthesia, restricted eye movement, and subconjunctival hemorrhage; urgent assessment is needed to prevent ocular morbidity. | Orbital fracture signs |
| 18 | How should a suspected retinal detachment be initially managed in the emergency setting? | While definitive treatment is surgical, initial steps include advising the patient to avoid pressure on the eye, keep the head elevated, and seek urgent ophthalmologic care. | Prompt referral is essential |
| 19 | What is the role of corticosteroids in the management of ocular trauma? | Corticosteroids may reduce inflammation and edema but must be used cautiously and under specialist guidance, as they are not universally indicated and can have systemic side effects. | Use with caution and expert advice |
| 20 | Which signs suggest a possible globe perforation rather than a superficial injury? | Signs include decreased visual acuity, irregular or teardrop-shaped pupil, extrusion of intraocular contents, hyphema, and low intraocular pressure; urgent intervention is required. | Serious signs = globe perforation |
