Question 01. Which red-eye feature is most concerning? A. Reduced vision with photophobiaB. Mild itch with unchanged visionC. A longstanding stable surface vesselD. Brief irritation that fully resolves

Question 02. Which symptom particularly supports allergic conjunctivitis? A. Prominent itchB. Sudden curtain-like field lossC. Severe deep painD. New afferent pupil defect

Question 03. A painless sharply defined subconjunctival bleed with normal vision most often represents what? A. Acute angle closureB. Optic neuritisC. Subconjunctival haemorrhageD. Retinal detachment

Question 04. Why ask about contact lenses in a red eye? A. They exclude corneal infectionB. They prove allergyC. They prevent epithelial defectsD. They increase concern for microbial keratitis

Question 05. Which finding suggests a corneal problem requiring urgent assessment? A. Focal corneal opacity with painB. Isolated mild lid crustingC. A normal transparent corneaD. Stable presbyopia

Question 06. Why avoid unsupervised steroid drops in an undiagnosed red eye? A. They can worsen some infectionsB. They always correct refractive errorC. They have no ocular adverse effectsD. They replace a corneal examination

Question 07. Redness, pain and reduced vision soon after eye surgery raises concern for what? A. Routine presbyopiaB. Stable myopiaC. Simple refractive adaptation aloneD. Postoperative intraocular infection

Question 08. Which combination suggests orbital involvement? A. Fever, proptosis and painful restricted movementsB. Bilateral itch aloneC. Painless isolated surface bleedingD. Stable near blur

Question 09. Can modest redness coexist with serious eye disease? A. No, severe disease is always intensely redB. Yes, appearance alone is not a severity measureC. Only with allergyD. Only with normal visual acuity

Question 10. Which return advice is appropriate after treatment for mild conjunctival symptoms? A. Continue unchanged treatment despite visual lossB. Wait until the bottle is empty regardless of symptomsC. Seek prompt review for new pain, photophobia or reduced visionD. Avoid all further eye examinations
