About this trial

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).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Is 18 years of age and has full legal capacity to volunteer (no max age requirement)

Baseline Ocular Surface Disease Index (OSDI) >13

Has mild to moderate MGD

Has best corrected visual acuity of 20/40 or better

Disqualifiers

Is participating in any other type of clinical or research study

Is currently pregnant, nursing, lactating, or planning a pregnancy

Is currently having >50% blockage of Meibomian glands in more than two eyelids or significant atrophy (i.e., severe MGD)

Trial outcomes

Primary outcomes

1

Change in tear lipid layer thickness

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

Time frame
Measured at baseline, 1-month, and 3 months
2

Change in tear thinning rate

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

Time frame
Measured at baseline, 1-month, and 3 months

Secondary outcomes

1

Change in Meibomian gland function

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.

Time frame
Measured at baseline, 1-month, and 3 months
2

Change in tear production rate

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.

Time frame
Measured at baseline, 1-month, and 3 months
3

Change in tear breakup time

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.

Time frame
Measured at baseline, 1-month, and 3 months
4

Change in Ocular Comfort

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.

Time frame
Measured at baseline, 1-month, and 3 months
