Purpose: We hypothesized that women with primary (pSS) and secondary Sjögren syndrome (sSS; with systemic lupus erythematosus [SLE] or rheumatoid arthritis [RA]) have meibomian gland dysfunction (MGD). We sought to test our hypothesis.
Methods: Subjects with pSS, sSS + SLE, sSS + RA, and non-SS-related MGD were recruited from the Sjögren's Syndrome Foundation or outpatient clinics at Tufts University School of Dental Medicine or Brigham and Women's Hospital.
Purpose: To evaluate the safety of the polycarbophil-based formulation Durasite in rabbits when administered chronically to intact eyes and acutely to eyes compromised by a corneal epithelial defect, penetrating corneal incision, or laser in situ keratomileusis (LASIK) flap. The rheological properties were evaluated to characterize the behavior of the formulation on the ocular surface.
Setting: Bausch & Lomb, Rochester, New York, USA.
Purpose: The Schirmer's test is commonly used in the clinic for the diagnosis of dry eye disease by measuring tear volume. This report describes a procedure which can be used to recover tears from the Schirmer strip for the measurement of multiple tear cytokines as well as matrix metalloproteinases (MMPs) by Luminex technology.
Methods: Cytokine and MMP recovery was determined by using spiked Schirmer strips presoaked with known cytokines or MMPs prepared in PBS with 1% BSA.
Purpose: This study's purpose was to determine whether complete androgen insensitivity syndrome (CAIS) is associated with alterations in the meibomian gland and ocular surface.
Methods: Individuals with CAIS, as well as age-matched female and male controls, completed questionnaires which assessed dry eye symptoms and underwent slit lamp evaluations of the tear film, tear meniscus, lids and lid margins and conjunctiva. The quality of meibomian gland secretions was also analyzed.
Objective: To determine whether androgen receptors affect the fatty acid profiles of neutral and polar lipids in human meibomian gland secretions.
Methods: Meibomian gland secretion samples were obtained from both eyes of (1) women with complete androgen insensitivity syndrome, a condition characterized by dysfunctional androgen receptors, and (2) age-matched female and male controls. Samples were processed for high-performance liquid chromatography, mass spectrometry, or both and for analysis of the mass spectra of neutral and polar lipid fatty acid fragment ions by 3 different methods.
