Episode 4 – Basic Ocular Physiology

Episode Description:

In this essential episode of Basic Sciences in Ophthalmology, we explore the dynamic processes that keep the eye functioning at its best. A must-listen for ophthalmology trainees, this episode introduces:

Tear production – the trilaminar film that protects and stabilizes the ocular surface

Aqueous humor flow – formation, circulation, and outflow pathways that regulate intraocular pressure

Neural retina physiology – how light becomes vision, including the phototransduction cascade

Each concept is clearly explained with clinical relevance and exam-ready clarity.

Episode 3: Take a closer look — literally — in this episode of Basic Sciences in Ophthalmology as we explore the eye under the microscope. Perfect for trainees and revision, this episode guides you through the key histological features of major ocular structures.

What you’ll learn:
- The layered architecture of the cornea and how it maintainstransparency
- The complex 10-layered structure of the retina, includingphotoreceptors and supporting neurons
- The microanatomy of the lens and ciliary body, including the role of epithelial and muscle layers in accommodation and aqueous humor production

This episode brings foundational histology into focus, linking microscopic structure with clinical significance.

Episode 2: Embryology of the Eye

In this foundational episode of Basic Sciences in Ophthalmology, we explore how the eye takes shape during early development. Designed for ophthalmology trainees, this episode breaks down the essential stages of ocular embryogenesis.

What you'll learn:
- Formation of the optic vesicles and optic cup
- How the lens is induced by surface ectoderm
- Common congenital anomalies like coloboma, microphthalmia, and more

Perfect for revising clinical concepts or preparing for exams. Join us as we unravel the science behind eye development.

Episode 1: Introduction to Ocular Anatomy

Welcome to the very first episode of Basic Sciences in Ophthalmology. I am your host Dr Thomas Whitelaw, and this podcast has been built for anyone interested in ophthalmology.

In this foundational episode, we break down the essential structural components of the eye and orbit, focusing on:

1. The three layers of the eyeball

2. The bones of the orbit and theirclinical significance

3. The six extraocular muscles andtheir nerve supply
