Each time we blink, the meibomian glands secrete lipids (meibum) onto the ocular surface, spreading the tear film. Meibum helps prevent tear evaporation, stabilizes the tear film, and promotes its distribution. During eye opening, tear fluid evaporates. Incomplete blinking occurs when the upper and lower eyelids don't fully touch, increasing tear evaporation. Studies show that blinking exercises reduce incomplete blinking and improve symptoms of dry eye and non-invasive tear break-up time (NIBUT) (Kim AD, et al., 2021). Although patients reported easier eyelid opening, the effect of blinking exercises on eyelid opening has not been documented. To assess this, we measured palpebral fissure height as indicators, alongside subjective symptoms and tear stability.
Efficacy
Confirmatory
Not applicable
palpebral fissure height (mm)
Subjective Symptoms
SPEED Score: Evaluates the frequency and severity of dry eye symptoms, scoring from 0 to 28.
Visual Analog Scale (VAS): Independently rates 8 symptoms (dryness, eye fatigue, discomfort, blurred vision, foreign body sensation, pain, heaviness, difficulty opening eyes) from 0 (no symptoms) to 100 (maximum symptoms).
Measurements using idra
Tear lipid layer thickness (nm)
Tear meniscus height (mm)
Blink quality (%), complete/incomplete blinks, duration (seconds)
Non-invasive tear break-up time (NIBUT first, average) (seconds)
Corneal and conjunctival epithelial damage score: Assessed using fluorescein staining (0-9).
Tear film break-up time with fluorescein (FBUT) (seconds): Average of 3 measurements.
