Purpose: The purpose of this study was to investigate the prevalence of lid wiper epitheliopathy (LWE) in patients diagnosed with dry eye disease (DED).
Methods: Patients were recruited for two groups. Inclusion criteria for the DED group (n = 50) was: a score greater than 10 with the Standard Patient Evaluation of Eye Dryness questionnaire, fluorescein break-up time 5 seconds or less, corneal and conjunctival staining with fluorescein, lissamine green Grade 1 or greater (scale 0-3), and Schirmer test with anesthesia 5 mm or less.
Purpose: Sodium fluorescein is considered the premier dye for corneal staining and, similarly, rose bengal (RB) for conjunctival staining. A mixture of 1% fluorescein and 1% rose bengal has been reported as advantageous in daily practice. Mixtures of lissamine green with other ocular stains have not been reported.

The purpose of this study was to investigate whether lid wiper epitheliopathy occurred with patients who reported dry eye symptoms, yet had normal fluorescein breakup time (FBUT) and Schirmer test values and an absence of fluorescein corneal staining.
Methods: One hundred patients were divided into two groups based on the presence or absence of dry eye symptoms, as determined with the Standard Patient Evaluation of Eye Dryness questionnaire.
Purpose: To evaluate whether dry-eye symptoms are associated with epitheliopathy of that portion of the upper eyelid marginal conjunctiva-the lid wiper-that wipes the ocular, or contact lens surface, during blinking.
Methods: Subjects were divided into two groups based on the presence or absence of dry-eye symptoms. The lid wiper of asymptomatic (n=75) and symptomatic (n=30) soft contact lens wearers was examined, following the instillation of fluorescein and rose bengal dyes.
