Ophthalmology questions and MCQs with answers

Every question is original and written to single-best-answer standards. That means a clinical vignette or focused stem, one option that is defensibly best, and distractors that are each plausible for a specific reason. The aim is to test clinical reasoning, such as recognizing a pattern, choosing the next step or explaining a mechanism, rather than recall of isolated trivia.

Before a question is published, an independent clinical reviewer checks the stem, the keyed answer and the explanation, and the clinical facts are checked against standard ophthalmology references. After publication, questions that residents flag as unclear or incorrect are reviewed and, where needed, revised or retired. The question quality page sets out the full editorial process.

The library follows the 13 sections of the Basic and Clinical Science Course: general medicine; fundamentals and principles of ophthalmology; clinical optics and vision rehabilitation; ophthalmic pathology and intraocular tumors; neuro-ophthalmology; pediatric ophthalmology and strabismus; oculofacial plastic and orbital surgery; external disease and cornea; uveitis and ocular inflammation; glaucoma; lens and cataract; retina and vitreous; and refractive surgery.

Because the sections follow a standard reading curriculum, you can pair a chapter with its question set and see which sections need more work. BCSC is a trademark of the American Academy of Ophthalmology and is named here only to describe how the library is organized. OphthoMentor is not affiliated with or endorsed by the AAO.

OKAP (Ophthalmic Knowledge Assessment Program): the annual in-training examination taken by ophthalmology residents. Its content areas broadly follow the BCSC sections, so practicing section by section can show you where to focus before the exam.

ABO Written Qualifying Examination (WQE): the multiple-choice examination in the American Board of Ophthalmology's initial certification process. It covers the full breadth of ophthalmology.

EBO Diploma (EBOD): the European Board of Ophthalmology Diploma examination. It has a written Part I (true/false MCQs and single-best-answer questions) and a Part II of clinical cases, taken as a face-to-face viva at in-person sittings or as typed answers at online sittings, and candidates who pass are awarded the title Fellow of the European Board of Ophthalmology (FEBO). The written questions here build the knowledge base for Part I.

FRCOphth: the Royal College of Ophthalmologists' Part 1 examination concentrates on the basic sciences, including anatomy, physiology, pathology and optics. The Part 2 written examination tests clinical ophthalmology. The fundamentals, clinical optics and pathology sections are most relevant to Part 1, and the clinical sections support Part 2.

Royal College (Canada): the Royal College of Physicians and Surgeons of Canada certification examination in ophthalmology has a written component and an applied component, and the written must be passed first. The written component covers the full specialty, so all 13 sections are relevant.

RANZCO (Australia and New Zealand): trainees sit the Ophthalmic Sciences, OBCK and Ophthalmic Pathology examinations during training and the RANZCO Advanced Clinical Examination (RACE) near its end. The fundamentals, clinical optics and pathology sections suit the early examinations, and the clinical sections support the RACE.

ICO: the International Council of Ophthalmology's examinations are taken by trainees in many countries and cover the visual sciences, optics and refraction, and clinical ophthalmology.

Question formats differ between these exams, and none of the examining bodies is affiliated with OphthoMentor. Much of the core knowledge they assess is shared, though.

Commit to an answer before you reveal it. Retrieving information from memory (active recall) strengthens retention more than rereading does.

Read the explanation even when you answered correctly. Knowing why each distractor fails is what helps you choose between two plausible options on exam day. Note the single finding in the stem that decided the answer.

Space your review. Spreading practice across days and weeks (spaced repetition) produces more durable learning than cramming the same material into one session. A free account adds spaced-repetition review, which brings questions back on a schedule, and a readiness dashboard that tracks your progress. Weak-topic drills then focus your practice on the subspecialties where you are weakest.
