Orbit,
You state in one post that you want to attack the root cause of DES, which I agree with. In another, you cite the high failure rate you've experienced with Restasis. If the patient has aqueous deficiency (not a quality issue from rosacea, blepharitis, demodex, etc), why avoid plugs when they can help the patient avoid artificial tears (the cost and the hassle)? Yes, placing plugs pays some and it may be overused by some, especially when the cause is a quality, not quantity, issue, but when basal secretion is low, they can be in the best interests of the patient, both convenience and financial in the long run.
I do prescribe Restasis, BTW. But I don't use it in place of other treatments for the focal quality issues you mention. My observation is only that, not an attack. Patients frequently give up on the drop, sometimes when they might try a little longer with some hope of improvement (reasons given are various, some of which are discomfort, some of which are frustration with perception of no improvement and at least some of those complaints are motivated by cost: if something that expensive doesn't work better than everything else, it isn't any good, etc.)
I also use occlusion, where I really think it will make a difference. The patient with rosacea, blepharitis, punctal phimosis and tear film deficiency who admits to using wetting drops only twice a day and is doing nothing to treat their blepharitis is generally not the patient that needs plugs. But I can't tell you how many of those kinds of folks I see coming in with plugs in or who have had plugs placed by someone else that have since been expelled.
A little history is in order, too. If I see a patient who has dry eye findings (low Schirmer, Lissamine uptake, etc), I ask how frequently they are applying drops. Usually the daily frequency is 0-2 times a day. That is most patients. I suppose I could plug those folks--a lot of doctors do, figuring that patients just won't apply drops more frequently even if asked--but I really think they deserve a better trial of drops, even of Restasis if appropriate.
I think early occlusion makes sense in patients who live alone or with only a same-aged partner who have dry eye and arthritis. Look at the patient's hands. Ask if their hands give them trouble. Those patients may give even a good history of compliance--maybe to please you--but you know that drops have to be difficult for them. But I don't agree with early use of plugs as an aid to laziness, for people who won't use artificial tears appropriately when they clearly could and should.
And I don't want to give the impression that I think autologous serum treatment is useless, I don't. But in far more cases than I like to admit, I have seen them used in patients that really didn't need them any more than they needed any other kind of unpreserved drop. For the pemphigoid patient, or S-J-S, burns, rheumatoid keratoconjunctivopathy, it is probably the way to go. For the post-LASIK patient with a clear flap, no surface disease, 20/20+ vision but who is on antidepressants with known anticholinergic side effects, no.
