FCPS Part 1 Ophthalmology: Cornea & Retina MCQs — High-Yield Concepts
A deep dive into the two largest subject pools in the FCPS Part 1 Ophthalmology bank — Cornea & External Disease and Retina & Vitreous — with sample MCQs and why they recur so often.

Cornea & External Disease and Retina & Vitreous are the two largest subject pools in HighYield's FCPS Part 1 Ophthalmology question bank — built directly from past papers, verified recalls and a dedicated ophthalmology MCQ textbook. Between everyday clinical volume and a dense set of classic, testable associations, these two subjects punch well above their weight in real exam sessions. Below is a sample across both.
Cornea & External Disease
1. Fluorescein staining of a corneal epithelial defect that branches with terminal bulbs is the classic dendritic appearance of:
- A) Bacterial keratitis
- B) Herpes simplex keratitis ✅
- C) Fungal keratitis
- D) Acanthamoeba keratitis
2. Keratoconus classically causes which pattern of astigmatism progression on serial refraction?
- A) Stable, regular astigmatism
- B) Progressive, irregular astigmatism ✅
- C) Progressive hyperopia only
- D) No refractive change
3. Contact lens wearers with a corneal ulcer are at particular risk from which organism, notorious for rapid stromal melting?
- A) Staphylococcus epidermidis
- B) Pseudomonas aeruginosa ✅
- C) Streptococcus viridans
- D) Propionibacterium acnes
Retina & Vitreous
4. A patient describes a sudden shower of floaters and flashes of light, followed by a curtain-like shadow across their visual field. This presentation is most concerning for:
- A) Posterior vitreous detachment alone
- B) Rhegmatogenous retinal detachment ✅
- C) Vitreous syneresis
- D) Migraine with aura
5. Dot-and-blot hemorrhages, microaneurysms and hard exudates on fundoscopy, without neovascularisation, describe:
- A) Proliferative diabetic retinopathy
- B) Non-proliferative diabetic retinopathy ✅
- C) Hypertensive retinopathy grade IV
- D) Central serous retinopathy
6. Age-related macular degeneration is classically divided into which two forms based on presence or absence of choroidal neovascularisation?
- A) Proliferative and non-proliferative
- B) Dry (non-neovascular) and wet (neovascular) ✅
- C) Central and peripheral
- D) Acute and chronic
Why These Two Subjects Are Worth Extra Time
Cornea & External Disease questions test a mix of pattern recognition (dendritic ulcers, ring infiltrates, staining patterns) and mechanism (why a contact lens wearer is at particular risk, why a particular organism causes rapid melting) — exactly the kind of question CPSP's item-analysis scoring favours because it separates candidates who understand the underlying process from those who've only memorised a single fact. Retina & Vitreous carries similar weight because its classic presentations — sudden painless vision loss, flashes and floaters, specific fundoscopic patterns — map cleanly onto one-best-answer vignettes, and the subject spans everything from vascular occlusions to degenerative disease, giving examiners a wide pool of distinguishable, testable concepts to draw from.
Looking for a Mock Exam, Not Just More Questions to Read?
If what you actually want is a timed FCPS Part 1 Ophthalmology mock exam — not another static list to read through — that's exactly what the free sample on the Ophthalmology question bank page gives you: the same timed, explained format as the full bank, no separate "mock test" product to buy or download.

Frequently Asked Questions
Are Cornea and Retina high-yield for FCPS Part 1 Ophthalmology?
Yes — across past papers and recall compilations, Cornea & External Disease and Retina & Vitreous are consistently among the largest, most frequently tested ophthalmology-specific subjects.
What kind of FCPS ophthalmology cornea questions come up most?
Classic pattern-recognition presentations — dendritic ulcers from herpes simplex, keratoconus progression, contact-lens-associated Pseudomonas keratitis — alongside corneal anatomy and physiology (which layer does what).
What kind of FCPS ophthalmology retina questions come up most?
Classic acute presentations (retinal detachment, central retinal artery/vein occlusion) and the distinguishing features of diabetic retinopathy stages and age-related macular degeneration subtypes.
