Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the effect of treatment with topical azithromycin or oral doxycycline on tear film thickness in patients with dry eye syndrome caused by meibomian gland dysfunction;Secondary Objective: To compare the effect of treatment with topical azithromycin or oral doxycycline in patients with dry eye syndrome caused by meibomian gland dysfunction on - Lipid layer thickness - Break up time (BUT) - Visual Acuity - Tear film osmolarity - Staining of the cornea with fluorescein - Impression cytology - Schirmer I test - Subjective symptoms of dry eye syndrome (OSDI© questionnaire) - Intraocular pressure - Meibography - Conjuctival staining with lissamine green - Corneal sensitivity - Signs and symptoms of MGD;Primary end point(s): The primary endpoint will be the difference in tear film thickness between the two groups after treatment;Timepoint(s) of evaluation of this end point: 2, 4 and 6 weeks after start of treatment | — |
Secondary
| Measure | Time frame |
