Welcome to your 🧠 Optic Neuritis, Optic Neuropathies & Papilledema Arena — 40 Integrated MCQs
1.
Which statement best distinguishes papilledema from the broader term optic-disc swelling?
2.
A patient with acute optic neuritis has profound bilateral involvement, unusual fundus changes and systemic inflammatory symptoms. Which management approach is most appropriate?
3.
A 24-year-old woman develops painful blurring of vision in one eye. Colour vision is reduced and a relative afferent pupillary defect is present. Fundoscopy shows a normal optic disc. Which form of optic neuritis is most likely?
4.
A patient with suspected demyelinating optic neuritis is being investigated. Which investigation is most useful for demonstrating optic nerve inflammation and associated cerebral demyelinating lesions?
5.
A patient has newly detected bilateral papilledema with headache. Which investigation should generally be performed before lumbar puncture when an intracranial mass must be excluded?
6.
A 30-year-old woman presents with headache, transient episodes of visual dimming and pulsatile tinnitus. Both optic discs are swollen, but central visual acuity and colour discrimination remain relatively preserved. Which interpretation is most appropriate?
7.
A patient has unilateral optic-disc swelling, marked loss of colour vision and a clear relative afferent pupillary defect. The fellow eye is normal. Which diagnosis is more likely than papilledema?
8.
A 56-year-old man is referred because both optic discs appear swollen. Before attributing the finding to raised intracranial pressure, which simple systemic assessment is particularly important because severe disease may produce a similar fundus appearance?
9.
A patient develops severe bilateral visual disturbance after ingestion of an illicit alcohol-containing liquid. Which toxic substance should be suspected?
10.
A 48-year-old woman with previous gastrointestinal surgery develops gradual, painless bilateral central visual loss. She has poor nutritional intake, dyschromatopsia and centrocecal field defects. What is the most appropriate management principle?
11.
A patient with unilateral optic neuritis undergoes a swinging-flashlight test. Which finding most strongly supports asymmetric optic nerve dysfunction?
12.
A young adult with suspected optic neuritis reports that red objects appear faded in the affected eye. Which visual function is impaired?
13.
A child develops slowly progressive, painless bilateral visual impairment with colour-vision abnormality and temporal optic-disc pallor. Which condition is most likely?
14.
A 25-year-old woman has acute painful monocular visual loss with reduced colour vision. Which visual-field abnormality is most characteristic of optic neuritis?
15.
A 27-year-old woman presents with acute unilateral visual loss associated with pain on eye movement. Which underlying process most commonly explains typical optic neuritis in this age group?
16.
A patient with confirmed papilledema develops horizontal diplopia. Examination demonstrates impaired abduction of one eye. Which neurological complication of raised intracranial pressure best explains this finding?
17.
A patient taking prolonged antituberculous therapy develops progressive bilateral reduction of central vision and colour discrimination. Visual fields show centrocecal defects. What is the most appropriate next step regarding the suspected offending treatment?
18.
A patient with typical acute demyelinating optic neuritis is considered for systemic corticosteroid therapy. What is the main expected benefit?
19.
A patient with persistent headache has bilateral hyperemic elevated optic discs with blurred margins, obscuration of vessels at the disc edge and venous congestion. Which physiological disturbance most directly contributes to these fundus changes?
20.
A 35-year-old man presents after ingesting an unregulated alcoholic preparation. He has systemic illness and rapidly progressive severe bilateral visual impairment. What is the most appropriate management principle?
21.
A patient with headache and vomiting has bilateral swollen optic discs. Visual acuity remains relatively preserved. Which diagnosis is most likely?
22.
Which visual-field abnormality is classically seen early in papilledema?
23.
A 23-year-old man develops painless central visual loss in one eye followed by similar loss in the other. Examination shows impaired colour vision and early peripapillary nerve-fibre swelling. Several maternal relatives have visual impairment. Which additional finding would best support the suspected hereditary disorder?
24.
A patient with papilledema develops progressive visual-field loss despite treatment. What is the most important management principle?
25.
A 12-year-old girl has slowly progressive bilateral visual impairment. Colour discrimination is abnormal and both optic discs show temporal pallor. Her father has a similar visual problem. Which diagnosis best explains this pattern?
26.
A 26-year-old woman with previous painful monocular visual loss has recovered substantially. A visual evoked potential still shows increased latency from the affected eye. Which process best explains this finding?
27.
A patient with long-standing untreated papilledema initially had preserved visual acuity but now has permanent reduction of vision and pale optic discs. Which process best accounts for this late deterioration?
28.
A 34-year-old woman presents with severe headache and bilateral optic-disc swelling. Initial brain imaging shows no intracranial mass. The clinical team suspects impaired cerebral venous drainage as the cause of raised intracranial pressure. Which investigation is particularly relevant?
29.
A patient receiving antituberculous treatment develops bilateral reduction of central vision and colour discrimination. Which drug is most strongly associated with this optic neuropathy?
30.
A 29-year-old woman has recurrent episodes of severe visual loss affecting both eyes. Recovery from previous attacks has been incomplete. The pattern is considered atypical for ordinary demyelinating optic neuritis. Which associated disorder should be specifically considered?
31.
A 45-year-old man has gradually progressive, painless bilateral central visual loss. Colour vision is reduced, visual fields show symmetrical centrocecal scotomas and the optic discs are relatively normal initially. He has no headache or pain on eye movement. Which clinical approach is most appropriate?
32.
A malnourished patient develops gradual painless bilateral central visual loss with impaired colour vision. Which diagnosis best fits this presentation?
33.
A woman with established papilledema reports little change in central visual acuity. Serial perimetry, however, shows progressive peripheral field deterioration. What is the most appropriate interpretation?
34.
A young obese woman has headache, pulsatile tinnitus and bilateral papilledema. Neuroimaging excludes a mass lesion and hydrocephalus. Which investigation is most appropriate next to support a diagnosis of idiopathic intracranial hypertension?
35.
A 22-year-old man develops painless central visual loss in one eye followed later by the other eye. His maternal relatives have had similar visual problems. Which diagnosis is most likely?
36.
A 21-year-old man develops subacute visual blurring and impaired colour perception. Fundoscopy shows optic-disc swelling with lipid exudates radiating around the macula in a star-shaped pattern. Which classification best fits this presentation?
37.
A patient with optic neuritis has visible swelling of the optic nerve head on fundoscopy. Which classification best describes this condition?
38.
A patient is reviewed several months after an episode of optic neuritis. Visual function has improved, but OCT demonstrates thinning of the retinal nerve-fibre layer. What does this structural change most strongly indicate?
39.
Which mode of inheritance is characteristic of Leber hereditary optic neuropathy?
40.
Which mechanism directly produces optic-disc edema in papilledema?
