Ocular Surface Health and Tear Film Stability With a Nasal Spray Dry Eye Treatment

22. mai 2026 oppdatert av: University of California, Berkeley

The Impact of Varenicline Nasal Spray 0.03mg Dry Eye Treatment on Ocular Surface Health, Tear Film Stability, and Ocular Discomfort

The purpose of this study is to examine the impact of nasal spray treatment on Meibomian gland function and ocular surface health in symptomatic dry eye patients with mild to moderate Meibomian gland dysfunction (MGD).

Detaljert beskrivelse

Dry eye disease is a common condition that occurs when eyes do not produce enough tears or when the quality of the tears is poor causing tears to evaporate quickly off the eye. This can lead to symptoms such as dryness, burning, irritation, and/or blurred vision. Meibomian gland dysfunction is the most common cause of evaporative dry eye disease. The purpose of this study is to examine the impact of nasal spray treatment on Meibomian gland function and ocular surface health in symptomatic dry eye patients with mild to moderate Meibomian gland dysfunction (MGD). The nasal spray is FDA approved for the treatment of signs and symptoms of dry eye disease.

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Change in tear lipid layer thickness
Tidsramme: Measured at baseline, 1-month, and 3 months
Change from baseline in the thickness of the tear lipid layer in microns measured using the EASYTEARView+ Dacryscope. An increase in tear lipid layer thickness is considered a positive treatment effect
Measured at baseline, 1-month, and 3 months
Change in tear thinning rate
Tidsramme: Measured at baseline, 1-month, and 3 months
Change from baseline in the rate of tear thinning in %/sec measured using the EASYTEARView+ Dacryscope. A decrease in the rate of tear thinning is considered a positive treatment effect
Measured at baseline, 1-month, and 3 months

Sekundære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Change in Meibomian gland function
Tidsramme: Measured at baseline, 1-month, and 3 months
Change from baseline in the clinical grade of meibum expressed from the Meibomian glands using the Korb Meibomian Gland Evaluator. Clinical grades assigned based on a 0-30 point scale, with 30 indicating copious, clear meibum and 0 indicating no meibum expressed (blocked orifices). An increase in score indicates improved gland function.
Measured at baseline, 1-month, and 3 months
Change in tear production rate
Tidsramme: Measured at baseline, 1-month, and 3 months
Change from baseline in the rate of tear production in µL/min, measured using the Schirmer Tear Test. An increase in tear production is considered a positive treatment effect.
Measured at baseline, 1-month, and 3 months
Change in tear breakup time
Tidsramme: Measured at baseline, 1-month, and 3 months
Change from baseline in non-invasive tear breakup time in seconds, measured using the Oculus Keratograph 5M. An increase in tear breakup time is considered a positive treatment effect.
Measured at baseline, 1-month, and 3 months
Change in Ocular Comfort
Tidsramme: Measured at baseline, 1-month, and 3 months
Change from baseline in ocular discomfort, measured using the Ocular Surface Disease Index (OSDI) on a 0-100 scale. A decrease in OSDI score is considered a positive treatment effect.
Measured at baseline, 1-month, and 3 months
