Effect of Sunflower Lecithin Supplementation on Meibomian Gland Function in Adults With Dry Eye Disease
March 14, 2024 updated by: George Washington University
This prospective study will evaluate the effect of oral sunflower lecithin dietary supplementation on meibomian gland function in adults with dry eye disease.

Detailed Description
Enrolled patients in the active arm of the study (n=20) will receive a daily dose of four sunflower lecithin 1,200 mg soft-gel capsules for a duration of 90 days.
Patients in the control arm (n=10) will receive four doses of a 1,000 mg placebo soft-gel capsules (containing olive oil).
Patients will be evaluated for meibomian gland function and signs and symptoms of dry eye at baseline and at the end of the study using a standardized eye dryness survey (SPEED survey), Tear Breakup Time Measurement, Meibomian Gland Score, and a rapid in-office assessment of years (InflammaDry).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Sunflower Lecithin
Total 4800 mg sunflower lecithin per day taken in 4 softgel capsules
|
Lecithins are a group of essential phospholipids that are involved in a number of biological functions such as lipid-cholesterol transport, transmembrane signaling, and neurological function

Placebo Comparator: Olive Oil
Total 4000 mg olive oil per day taken in 4 softgel capsules
|
Extra virgin olive oil

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from Baseline of the SPEED questionnaire score at Day 90
Time Frame: 90 days
|
To assess the improvement of dry eye symptoms by SPEED questionnaire.
0 score is the minimum (no dry eye symptom); 64 is the maximum score (most symptomatic).
Change = (Day 90 score - Baseline score)
|
90 days
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from Baseline of Fluorescein Tear Break-Up Time (Seconds) at Day 90
Time Frame: 90 days
|
Fluorescein Tear Break-Up Time (TBUT) is a measurement in seconds of tear film stability.
The shorter the TBUT, the lower the tear film stability.
Lower tear film stability is associated with dry eye.
Change = (Day 90 value - Baseline value)
|
90 days
|
Change in number of MMP-positive eyes at Day 90
Time Frame: 90 days
|
InflammaDry is a noninvasive immunoassay for detecting the presence of MMP-9 in tears.
|
90 days
|
Least Squares Mean Change from Baseline in Meibomian Gland Score (MGS) at Day 90
Time Frame: 90 days
|
Meibomian glands on the eyelids assessed by the examiner using a Meibomian Gland Evaluator (MGE) and a slit lamp microscope.
An MGE instrument applies a standardized force simulating the pressure of a deliberate blink allowing eye care professionals to observe meibomian gland functionality through a slit lamp.
5 glands in 1 zone (nasal) evaluated for each eye and scored from 0 to 3, with a resultant overall score (MGS) of 0 to 15 for each eye.
Scoring as follows: 0 = no secretion (worst), 1 = inspissated, 2 = cloudy, 3 = clear liquid (best).
A higher change from baseline score indicates an improvement in meibomian gland function.
