Outcome Measures
Primary Outcomes (1)
Tear film break-up time
The multi-colored Placido disk will collect images of the tear film with the aim to have usable data for more extended periods of time. This instrument measures tear film break-up time in seconds using a video recording of the tear surface.
up to 3 seconds
Study Arms (2)
Dry Eye Disease or Sjogren's Disease
OTHERCapturing images of the tear surface using the multi-colored Placido disk
Control
OTHERCapturing images of the tear surface using the multi-colored Placido disk
Interventions
The multi-colored Placido disk instrument records the tear surface using video imaging.
Eligibility Criteria
