How to Evaluate the Lid and Ocular Surface
Recognizing minor signs of underlying ocular surface or lid disease requires a thorough evaluation. Here’s a guide to a comprehensive exam of the ocular surface.

The ocular surface is comprised of the cornea, conjunctiva, eyelids, eyelashes, tear film, main and accessory lacrimal glands and meibomian glands.
The eyelids play a major role in protecting and spreading the moisture over the ocular surface.
The lower eyelid supports the tear film, and the glands of Zeiss and Moll, as well as the meibomian glands, secrete lipids.
The blinking action stimulates the release of lipids into the tear film as well as moves the tear film towards the puncta. Any disruption in the normal anatomy and physiology of this system can cause the patient to become symptomatic of ocular surface pathology.
