Neuro-Ophthalmology MCQs & Guide
350+ questions with detailed explanations. Master neuro-ophthalmology for FRCOphth, ICO, FAICO, DNB and NEET-SS.
Neuro-Ophthalmology overview
Neuro-ophthalmology sits at the interface of ophthalmology and neurology — pupils, optic nerve, visual pathways, ocular motility and higher cortical visual function. Pattern recognition is everything.
Clinical & exam importance
Neuro-ophth questions are 8–12% of most exams. Anisocoria workup, RAPD, papilloedema vs pseudopapilloedema and field defect localisation are perennial favourites.

Core anatomy & physiology refresher
The foundations you need before tackling clinical and surgical MCQs.
- Visual pathway: retina → optic nerve → chiasm → optic tract → LGN → optic radiations → primary visual cortex (V1).
- Optic nerve has four parts: intraocular (1 mm), intraorbital (25 mm), intracanalicular (9 mm), intracranial (16 mm).
- Pupillary light reflex: afferent CN II → pretectal nucleus → bilateral Edinger-Westphal → CN III → ciliary ganglion → short ciliary nerves → sphincter pupillae.
- Sympathetic pathway (3 neurons): hypothalamus → ciliospinal centre of Budge → superior cervical ganglion → carotid plexus → long ciliary nerves to dilator.
- Cavernous sinus contents: CN III, IV, V1, V2, VI and internal carotid artery.
High-yield neuro-ophthalmology facts for MCQs
The facts that appear most often in real exam stems. Learn them cold.
- 1RAPD localises to optic nerve disease or extensive retinal disease — not media opacity.
- 2Optic neuritis: young women, painful loss of vision, RAPD, MRI shows demyelinating plaques.
- 3AION (arteritic vs non-arteritic): GCA must be ruled out in any patient >50 with sudden vision loss; check ESR, CRP.
- 4Papilloedema: bilateral disc swelling from raised ICP; check BP, neuroimaging, LP if no mass.
- 5Pseudotumor cerebri: young obese women, headache, papilloedema, normal imaging, raised opening pressure.
- 6Adie pupil: dilated tonic pupil, sectoral palsy, vermiform movements, constricts to dilute pilocarpine 0.125%.
- 7Argyll Robertson pupil: small irregular, light-near dissociation, classic for neurosyphilis.
- 8Horner syndrome: ptosis, miosis, anhidrosis; first-order (stroke), second-order (Pancoast), third-order (carotid dissection).
- 9CN III palsy: pupil-sparing suggests microvascular (diabetes); pupil-involving suggests aneurysm (PCom).
- 10CN IV palsy: vertical diplopia worse on contralateral gaze, head tilt to opposite side compensates.
- 11CN VI palsy: horizontal diplopia worse at distance; raised ICP is a non-localising cause.
- 12Internuclear ophthalmoplegia: MLF lesion; ipsilateral adduction failure with contralateral abducting nystagmus.
- 13Bitemporal hemianopia: chiasmal lesion, usually pituitary adenoma or craniopharyngioma.
- 14Homonymous hemianopia: retrochiasmal lesion; congruity increases the more posterior.
- 15Macular sparing in homonymous hemianopia suggests occipital lobe (dual blood supply).

Free neuro-ophthalmology sample MCQs
A taste of the exam-style stems from the full bank.
Q1.A relative afferent pupillary defect (RAPD) localises pathology to:
Explanation: RAPD reflects asymmetric afferent input – usually optic nerve disease or large retinal pathology; never caused by media opacities like cataract.
Q2.A pituitary adenoma compressing the chiasm classically causes:
Explanation: Chiasmal compression interrupts decussating nasal retinal fibres producing bitemporal hemianopia.
Q3.Light-near dissociation with small irregular pupils is termed:
Explanation: Argyll Robertson pupils ("prostitute's pupils") are small, irregular pupils that accommodate but do not react to light; classically associated with neurosyphilis.
