Question: Why is manual expression at the slit lamp important?

While automated expression devices are efficient and provide consistent results, manual expression as shown here provides incredibly helpful information about the qualitative features of the meibum. Here, we see surprising contents of a meibomian gland. It is multi-layered meibum which gives us information about the type of oils that are being produced by the glands and even exogenous material that enters into the glands. Moreover, watching the fluid dynamics of expression gives us hints about the physical characteristics of the oils such as viscosity and this observation potentially helps us make clinically important decisions.  #mgd #dryeyes #ophthalmology#visionaries #cornea @FishmanVision(instagram) @drfishman – Twitter)
