Episode 28 – Tear Film and Dry Eye Disease

Hi - I'm Dr Thomas Whitelaw - welcome back to "Basic Sciences in Ophthalmology" - this is Episode 28 - I hope you enjoyt it.This episode of Basic Sciences in Ophthalmology explores the essential structure and function of the tear film and its disruption in dry eye disease.

We examine each tear film layer, outline key causes of tear dysfunction including aqueous deficiency and evaporative loss—and walk through diagnostic methods like Schirmer and TBUT tests.

A concise yet thorough guide for clinicians and trainees alike.

Episode 27 - Basic Biochemistry of the Eye

Welcome to Basic Sciences in Ophthalmology, the podcast that breaks down complex ocular science into essential learning for aspiring ophthalmologists. I'm your host, Dr Thomas Whitelaw and in today’s Episode 27, we delve into the Basic Biochemistry of the Eye — a critical area to understand how the eye functions at a molecular level.

Episode 26 – Pachymetry & Corneal Topography

Hi, I am your host, Dr Thomas Whitelaw and in this episode of Basic Sciences in Ophthalmology, we delve into the essential diagnostics behind corneal shape and structure. Learn how measuring corneal thickness and curvature helps identify disease early — and why it matters in glaucoma, refractive surgery, and especially keratoconus.

We clarify the difference between topography and tomography, walk through common imaging systems, and highlight how these tools guide clinical decisions.

Ideal for trainees, surgeons, and curious clinicians looking to enhance their diagnostic acumen.
