Summary
Compare the objective tear film dynamic measurements in three different populations (MGD
[Meibomium Gland Dysfunction], ADDE [Aqueous Deficient Dry Eye] and normal/control [non-dry
eye]) and the subjective experience before and after instilling a single drop of saline in
each eye.
Currently available office-based tests for dry eye do not reliably correlate with patients'
subjective symptoms. This study is interested in assessing how individuals with these two
different ocular surface diseases compare with the normal population when measured
objectively using two different instruments.
