Tear film comprises three layers: aqueous, mucin, and lipid.
Meibomian Gland Deficiency (MGD) causes a reduction in the lipid
(oily) layer of the tear film. This leads to evaporative dry eye
(short TBUT -- or Tear BreakUp Time). This is tear QUALITY. It IS
quite possible, based on your description, that this is what you have,
but it's relatively easily diagnosed by a qualified dry eye doc.
Aqueous deficient dry eye (lacrimal gland insufficiency) leads to low
Schirmer's test scores. This is tear QUANTITY (largely).
Damage to, or dysfunction of, the goblet cells leads to decreased
mucin production. This, too, can cause evaporative dry eye. This is
tear QUALITY.
There are all kinds of dry eye. Restasis CAN be useful, primarily in
aqueous deficient (quantity) issues, but is certainly far from a
guaranteed fix.
My best recommendation would be to visit:
www.dryeyezone.com
Review the introductory material, read the FAQ's, and browse around a
bit. Then join the forum and talk with all of the DES sufferers
there. They're a good bunch.
Tell 'em Neil sent you ;-)
Take care....
