1 Use infrared light to uncover hidden treasures

If you are lucky enough to have a background illuminating system, employ infrared light to visualise the meibomian glands to aid in a dry eye workup. Meibomian gland dysfunction (MGD) is thought to be the leading cause of evaporative dry eye, a condition which accounts for up to 80 per cent of dry eye cases.1

The International Workshop on Meibomian Gland Dysfunction defined MGD as ‘a chronic, diffuse abnormality of the meibomian glands, commonly characterised by terminal duct obstruction and/or qualitative/quantitative changes in the granular secretion’.2 Infrared meibography allows non-invasive, in-vivo assessment of the structure of the meibomian glands.
