Retina MCQs & Guide
600+ questions with detailed explanations. Master retina for FRCOphth, ICO, FAICO, DNB and NEET-SS.
Retina overview
Retina is the highest-weighted single subspecialty across modern ophthalmology exams — typically 18–25% of MCQs in FRCOphth Part 2, FICO and NEET-SS. The field has accelerated with anti-VEGF therapy, OCT, OCTA and gene therapy.
Clinical & exam importance
Diabetic retinopathy and AMD account for the bulk of blindness in working-age and elderly populations respectively. Retinal detachment is a surgical emergency. NEET-SS rankers are made or broken on the retina paper.

Core anatomy & physiology refresher
The foundations you need before tackling clinical and surgical MCQs.
- Ten retinal layers; inner retina supplied by central retinal artery, outer retina by choriocapillaris via Bruch membrane.
- Macula is the central 5.5 mm, fovea 1.5 mm, foveola 0.35 mm — cone-only avascular zone.
- RPE has six key functions: phagocytosis, visual cycle, blood-retinal barrier, melanin absorption, growth factor secretion, ion transport.
- Bruch membrane: five layers between RPE and choriocapillaris; thickens with age, central to AMD.
- Vitreous is 99% water with hyaluronic acid and type II collagen; PVD typically by age 65.
High-yield retina facts for MCQs
The facts that appear most often in real exam stems. Learn them cold.
- 1Diabetic retinopathy staging (ETDRS): mild/moderate/severe NPDR, then PDR.
- 2Severe NPDR rule: 4 quadrants of haemorrhages, 2 quadrants venous beading, 1 quadrant IRMA (4-2-1 rule).
- 3PDR features: NVD, NVE, vitreous haemorrhage, tractional retinal detachment.
- 4DMO is the leading cause of vision loss in diabetic patients; treat with anti-VEGF +/- focal laser.
- 5AMD: dry (drusen, geographic atrophy) vs wet (CNV). Anti-VEGF for wet AMD.
- 6Rhegmatogenous RD: PVD with break, photopsia and floaters, curtain-like field loss.
- 7Macular hole stages (Gass): 1 (impending) → 2 (small full thickness) → 3 (>400 µm) → 4 (with PVD).
- 8CRVO: blood and thunder fundus, 4 quadrants of haemorrhage; ischaemic vs non-ischaemic by RAPD and FFA.
- 9BRVO most commonly at superotemporal AV crossings; treat macular oedema with anti-VEGF.
- 10Retinitis pigmentosa: triad of bone-spicule pigmentation, attenuated arterioles, waxy disc pallor.
- 11Best disease: vitelliform lesion with reduced Arden ratio on EOG; BEST1/VMD2 gene.
- 12Stargardt: pisciform flecks, dark choroid on FFA, ABCA4 gene.
- 13Central serous retinopathy: young men, type A personality, steroids; treat conservatively first.
- 14OCT layers to identify: ILM, NFL, GCL, IPL, INL, OPL, ONL, ELM, EZ, IZ, RPE/Bruch.
- 15OCTA detects flow without dye; useful in CNV, ischaemic maculopathy and capillary dropout in DR.

25 free retina MCQs with explanations
Exam-pattern stems with the correct option marked and the reasoning spelled out. Open a question to check your answer.
Q1.Earliest sign of diabetic retinopathy is:
Explanation: Microaneurysms (small saccular outpouchings of capillaries) are the earliest visible sign of non-proliferative diabetic retinopathy.
Q2.High-risk PDR per ETDRS criteria includes NVD ≥1/4–1/3 disc area OR:
Explanation: High-risk PDR: NVD ≥1/4–1/3 disc area, OR any NVD with VH/preretinal haemorrhage, OR NVE ≥1/2 disc area with VH/preretinal haemorrhage.
Q3.First-line treatment for centre-involving DME with vision 6/12 or worse:
Explanation: Per DRCR.net Protocols T/V, intravitreal anti-VEGF is first-line for centre-involving DME with decreased vision. Laser remains an option for selected non-centre or refractory eyes.
Q4.Sudden painless monocular loss of vision with a cherry-red spot is most consistent with:
Explanation: CRAO causes acute painless severe vision loss with a pale ischemic retina and cherry-red spot (intact foveal choroidal perfusion).
Q5.Cherry-red spot in a child with hepatosplenomegaly suggests:
Explanation: Cherry-red spot in storage disorders: Tay-Sachs (no organomegaly classically), Sandhoff, Niemann-Pick. With hepatosplenomegaly think Niemann-Pick / Sandhoff; among options Tay-Sachs is the classic association.
Q6.Roth spots are:
Explanation: Roth spots are flame-shaped haemorrhages with central pale (white) areas. Causes: endocarditis, leukemia, severe anaemia, diabetes, HIV.
Q7.Most useful imaging for an early macular hole:
Explanation: SD-OCT shows the foveal architecture and is the gold standard to stage and follow macular holes (Gass / IVTS classifications).
Q8.A 60-year-old with sudden flashes, floaters, and a curtain of vision loss most likely has:
Explanation: Flashes (photopsia) and a sudden shower of floaters in an older adult should prompt urgent retinal examination to rule out PVD with retinal tear or rhegmatogenous detachment.
Q9.Most common type of age-related macular degeneration:
Explanation: Dry AMD (drusen ± geographic atrophy) accounts for ~85-90% of cases; wet AMD causes most severe vision loss.
Q10.Most common cause of vitreous haemorrhage in adults in developed countries:
Explanation: PDR is the leading cause of vitreous haemorrhage in adults; PVD-related tear is the commonest non-diabetic cause.
Q11.Anti-VEGF agents act primarily by:
Explanation: Aflibercept, ranibizumab, bevacizumab and brolucizumab bind VEGF-A (aflibercept also VEGF-B and PlGF), reducing vascular leak and neovascularisation.
Q12.In sickle cell retinopathy, sea fan neovascularisation appears:
Explanation: Sea fans are characteristic peripheral neovascular tufts in proliferative sickle retinopathy (Goldberg stage III), usually treated with scatter laser if progressive.
Q13.Best disease (vitelliform dystrophy) shows on EOG:
Explanation: Best disease shows a markedly reduced Arden ratio (<1.5) on EOG, with normal full-field ERG.
Q14.Retinitis pigmentosa typically presents with:
Explanation: RP: progressive rod-cone dystrophy presenting with night blindness, ring scotoma, bone-spicule pigmentation, and ultimately tunnel vision.
Q15.Coats disease classically presents in:
Explanation: Coats: unilateral idiopathic retinal telangiectasias causing massive exudation and detachment, predominantly in young males.
Q16.Most common malignant intraocular tumour in adults:
Explanation: Metastatic carcinoma (commonly breast in women, lung in men) is the most common malignant intraocular tumour in adults; melanoma is the commonest primary.
Q17.Photoreceptor type primarily responsible for scotopic vision:
Explanation: Rods (containing rhodopsin) mediate vision in low light (scotopic); cones mediate photopic and colour vision.
Q18.The retinal pigment epithelium is critical for:
Explanation: RPE functions include phagocytosis of shed outer segments, vitamin A retinoid (visual cycle) recycling, ion/fluid transport and blood-retinal barrier.
Q19.Most common cause of central retinal vein occlusion in elderly:
Explanation: Systemic hypertension and arteriosclerotic compression of the central retinal vein at the lamina cribrosa are the leading risk factors for CRVO in the elderly.
Q20.Frosted branch angiitis is associated with:
Explanation: Frosted branch angiitis presents as dramatic perivascular sheathing; associated with CMV (especially HIV), Behçet, leukemia, lymphoma and idiopathic.
Q21.Treatment for stage 3 zone II ROP with plus disease:
Explanation: Type 1 ROP (per ETROP) is treated with laser ablation of the peripheral avascular retina; intravitreal anti-VEGF (e.g. bevacizumab) is an effective alternative especially for zone I disease.
Q22.Central serous chorioretinopathy classically affects:
Explanation: CSCR predominantly affects men 20-50 years; risk factors include type A personality, glucocorticoid use, sleep apnea, pregnancy, and Cushing syndrome.
Q23.Drusen are deposits found between:
Explanation: Drusen are extracellular deposits located between the RPE basement membrane and the inner collagenous layer of Bruch membrane; hallmark of AMD.
Q24.Most common indication for pars plana vitrectomy:
Explanation: PPV is most often performed for vitreous haemorrhage, complex/tractional retinal detachment, epiretinal membrane, macular hole, and complicated diabetic eye disease.
Q25.Branch retinal vein occlusion is most often located at:
Explanation: BRVO usually occurs at arteriovenous crossings (commonly superotemporal) where a sclerosed artery compresses the underlying vein.
