FRCOphth Part 1 Physiology
Ocular physiology and biochemistry ties the anatomy to how the eye works, and it is a rich source of FRCOphth Part 1 questions. This guide covers the key systems to revise and how to consolidate them with exam-style single best answer (SBA) questions.

What physiology covers in Part 1
Cover aqueous humour production and outflow and its role in intraocular pressure, corneal transparency and hydration, the tear film, phototransduction and the retinal pigment epithelium, the pupillary light and near pathways, accommodation, the retinal and choroidal circulations, and the biochemistry of the lens. Understanding why a system behaves as it does is far more durable than memorising isolated values.
Where physiology overlaps, and why that helps
Physiology sits between anatomy and pharmacology: aqueous dynamics explains how anti-glaucoma drugs work, and phototransduction underlies much of retinal disease. Revising these links, rather than each fact in isolation, means one concept answers several questions and the material sticks.
How to revise physiology with a question bank
Use exam-style SBAs to test the mechanism, not just the fact, then lean on the referenced explanations and the AI tutor to reconstruct the reasoning where you slipped. Interleave physiology with the related anatomy and pharmacology so the connections reinforce each other.
