Arms Assigned Interventions
Doxycycline: Active Comparator
Oral doxycycline
Drug: doxycycline
Oral doxycycline 100mg bid
essential fatty acid: Active Comparator
Oral essential fatty acid
Drug: essential fatty acid
Oral essential fatty acid 1000mg per day
azithromycin: Active Comparator
Topical azithromycin daily to the conjunctival culdesac
Drug: azithromycin
topical 1% azithromycin daily to eye

Detailed Description:

Subjects with meibomian gland dysfunction undergo expression of the meibomian gland secretion prior to beginning treatment with either oral doxycycline, oral essential fatty acids, or topical azithromycin solution. Doxycycline is dosed at 100 mg bid; essential fatty acid is dosed at 1000 mg per day; topical azithromycin is delivered once per day as a 1% solution. Treatment with doxycycline is for two months; treatment with essential fatty acids is for two months; treatment with topical azithromycin is for one month. Following treatment, meibomian glands are again expressed and the lipids measured by spectroscopy (FTIR, MALDI-TOF, NMR)for characterization of structure and function. Analysis for presence of doxcycline or azithromycin is also performed. Changes in lipid parameters are correlated with clinical signs and symptoms of disease.
