Question 01. Which finding supports orbital rather than uncomplicated preseptal infection? A. Painful restricted eye movementsB. Mild isolated lid redness with normal movementsC. Unchanged central acuity aloneD. A normal pupil alone

Question 02. Fever, proptosis and reduced vision require what? A. Routine lid hygiene aloneB. Annual eye reviewC. Emergency hospital assessmentD. Waiting for spontaneous drainage

Question 03. Why document visual function repeatedly in orbital cellulitis? A. It removes the need for treatmentB. It measures sinus anatomyC. It guarantees no abscessD. Vision can deteriorate as orbital disease progresses

Question 07. Which lifestyle factor deserves particular attention in thyroid eye disease? A. SmokingB. Spectacle frame colourC. Dominant hand aloneD. Reading font alone

Question 08. Reduced colour vision and acuity in thyroid eye disease raise concern for what? A. Optic nerve compromiseB. A purely cosmetic problemC. Normal variation requiring no reviewD. Presbyopia alone

Question 09. Can serious thyroid optic neuropathy occur without striking proptosis? A. YesB. No, appearance excludes itC. Only with complete lid closureD. Only after retinal surgery
