Glaucoma MCQs & Guide
500+ questions with detailed explanations. Master glaucoma for FRCOphth, ICO, FAICO, DNB and NEET-SS.
Glaucoma overview
Glaucoma is a group of optic neuropathies characterised by progressive retinal ganglion cell loss, optic disc cupping and visual field defects, usually but not always associated with raised intraocular pressure (IOP). It is the second leading cause of irreversible blindness worldwide.
Clinical & exam importance
Glaucoma carries the highest weighting after retina across most ophthalmology exams — typically 12–18% of MCQs. Surgical decision-making (trabeculectomy vs tube vs MIGS) and field interpretation dominate viva questions in FAICO and DNB practicals.

Core anatomy & physiology refresher
The foundations you need before tackling clinical and surgical MCQs.
- Aqueous humour is secreted by the non-pigmented ciliary epithelium (pars plicata) at 2–3 µL/min.
- Drainage: 80–90% via the trabecular meshwork into Schlemm canal, 10–20% via the uveoscleral pathway.
- Trabecular meshwork has three layers: uveal, corneoscleral and juxtacanalicular (greatest outflow resistance).
- Normal IOP range is 10–21 mmHg with diurnal variation up to 4–5 mmHg.
- Optic nerve head has ~1.2 million axons converging through the lamina cribrosa.
High-yield glaucoma facts for MCQs
The facts that appear most often in real exam stems. Learn them cold.
- 1Primary open angle glaucoma (POAG) is the most common adult glaucoma worldwide.
- 2First-line medical therapy is a prostaglandin analogue (latanoprost, travoprost, bimatoprost).
- 3Risk factors for POAG: raised IOP, family history, African ancestry, age, thin central cornea, myopia.
- 4CCT correction: thin cornea underestimates true IOP; thick cornea overestimates.
- 5Angle closure: pupillary block (most common), plateau iris, phacomorphic, malignant glaucoma.
- 6Acute angle closure attack: pain, headache, nausea, halos, mid-dilated fixed pupil, IOP often 40–80 mmHg.
- 7Acute treatment: IV acetazolamide, topical beta-blocker, alpha agonist and pilocarpine after IOP drops, then YAG PI.
- 8Normal tension glaucoma: progressive optic neuropathy with IOP consistently <21 mmHg; consider migraine and vasospasm.
- 9Pseudoexfoliation: dandruff-like material on lens; high IOP spikes; often unilateral or asymmetric.
- 10Pigmentary glaucoma: Krukenberg spindle, mid-peripheral iris transillumination, young myopic men.
- 11Congenital glaucoma triad: epiphora, photophobia, blepharospasm. Buphthalmos and Haab striae on exam.
- 12Surgical ladder: SLT → MIGS (iStent, Hydrus, XEN) → trabeculectomy → tube shunt → cyclodestruction.
- 13Trabeculectomy complications: hypotony, choroidal effusion, bleb leak, blebitis, endophthalmitis.
- 14Visual field defects progress: paracentral scotoma → nasal step → arcuate scotoma → tunnel vision.
- 15OCT RNFL is most sensitive in early glaucoma; macular GCC adds value in advanced disease.

Free glaucoma sample MCQs
A taste of the exam-style stems from the full bank.
Q1.In primary open-angle glaucoma the most reliable structural test for early damage is:
Explanation: OCT of the peripapillary RNFL and macular ganglion cell complex detects structural loss earlier than visual field defects in POAG.
Q2.Classic visual field defect in glaucoma:
Explanation: Glaucomatous field loss follows the arcuate nerve fibre pattern and respects the horizontal meridian (nasal step, arcuate, Bjerrum scotoma).
Q3.First-line medical therapy for primary open-angle glaucoma:
Explanation: Prostaglandin analogues (latanoprost, travoprost, bimatoprost, tafluprost) are first-line for POAG: best IOP lowering, once-daily dosing, few systemic effects.
