5. Study Description
Brief Summary
The objectives of this study are:
To compare the change in levels of tear proteins and inflammatory mediators pre and post administration between the intranasal and extranasal applications
To compare the goblet cell count following application between the intranasal and extranasal applications
To compare fluorescein tear clearance with the application of the device intranasally and extranasally applications
Detailed Description
In this study, subjects will participate for three study days during up to a 44 day period, consisting of a screening examination to determine eligibility on one day and study applications on two different days. There are two applications, intranasal and extranasal. Subjects will receive both applications, in random sequence, one at each of the two application days (Visit 2 and Visit 3). The two applications consist of:
Active intranasal device application
Active extranasal device application
