[PDF][PDF] Importance of the lipid layer in human tear film stability and evaporation

JP Craig, A Tomlinson - Optometry and vision science, 1997 - academia.edu
Purpose. Previous work on rabbits has demonstrated a four-fold increase in tear evaporation
when the tear lipid layer is removed. However, in vitro work has suggested that the lipid
layer does not play a role in retarding evaporation of the aqueous layer. The importance of
the lipid layer in human tear film stability and evaporation was determined in the current
study by measurement of these parameters in the same individuals. Methods. The left eyes
of 161 normal and dry eye subjects (72 males, 89 females), with an age range of 13 to 85 …
