MRCSI (Ophth) Written study guide
MRCSI (Ophth) Written · Work through your exam, one topic at a time.
The MRCSI (Ophth) Written - also referred to as the MRCS Ophthalmology Written examination - is a professional surgical examination administered by the Royal College of Surgeons in Ireland (RCSI). It sits within RCSI's ophthalmology examinations portfolio, which the College lists alongside its FRCS and MRCS, otolaryngology and Court of Examiners pages under the Surgical Exams section of its website. Candidates are typically ophthalmology trainees and international medical graduates working towards membership-level recognition in ophthalmic surgery, who need to demonstrate a structured, broad-based knowledge of the specialty alongside general surgical principles. Because the College's dedicated page for this examination could not be retrieved, this profile does not state a question count, time allowance, pass mark, fee, format, retake policy or validity period; those details must be confirmed directly with RCSI before you plan your preparation or book a sitting. Topics on this exam: Ophthalmology and General Surgery. The MRCSI (Ophth) Written study guide has 2 sections and about 534 words.
01Ophthalmology: Structure, Pathology and Clinical Reasoning
The Ophthalmology paper rewards a layered understanding: anatomy and physiology (cornea, aqueous outflow, lens, retina, optic nerve), then pathology, then clinical decision-making. Be fluent in the aqueous circulation (ciliary body → posterior chamber → pupil → anterior chamber → trabecular meshwork/Schlemm canal), because it underpins glaucoma questions. Know the layers of the cornea and which dystrophies affect which layer, the difference between open-angle and angle-closure mechanisms, and the classic retinal diagnoses (retinal detachment, vein occlusion, diabetic retinopathy, macular degeneration). Questions frequently test the distinction rather than the definition.

The General Surgery component tests principles more than operative detail: perioperative risk assessment, wound healing, fluid and electrolyte balance, sepsis, and the recognition of the acute abdomen. Be confident with the surgical sieve (congenital, inflammatory, neoplastic, traumatic, vascular, metabolic) and with shock physiology . Understand the phases of wound healing (haemostasis, inflammation, proliferation, remodelling) and factors that impair it (diabetes, steroids, ischaemia, infection). Questions often present a stable-looking patient with a red flag (rigid abdomen, absent bowel sounds, rising lactate) and ask for the next step; the answer is usually resuscitation and urgent senior review/surgical referral , not a scan in isolation.
