Tear film osmolarity in patients with thyroid ophthalmopathy

“…3 A relationship between decreased tear secretion and elevated tear fi lm osmolarity was fi rst proposed by von Bahr in 1941. 11 Elevated tear fi lm osmolarity may be secondary to a decrease in tear secretion because of lacrimal gland disease (tear defi ciency), or an increase in tear fi lm evaporation (tear suffi ciency). 3 One of the most important functions of the eyelids is to resurface the eye with tears through blinking.…”

Evaluation of tear evaporation from ocular surface by functional infrared thermography

“…The tear evaporation measurement was first performed on rabbits using a chamber fixed around their corneas 9 and the evaporative rate was found to be 41.6ϫ 10 −7 g cm −2 s −1 . Two other similar studies were performed 10,11 which gave the values of 7.8ϫ 10 −7 ͑Ref.…”
