This prospective, interventional, randomized, controlled, double-blind clinical study evaluates the effect of Low-Level Light Therapy (LLLT) delivered by a polychromatic periocular mask (Eye-light®️) versus a sham device in adults with dry eye disease (DED) associated with Graves' ophthalmopathy, refractory to conventional topical treatment. The LLLT protocol applies photobiomodulation to eyelid and periocular tissues to support meibomian gland function and reduce tear inflammatory biomarkers. The primary endpoint is the change in tear film stability measured by Non-Invasive Tear Break-Up Time (NIBUT) and Fluorescein Tear Break-Up Time (FBUT). Secondary outcomes include symptom scores (OSDI), Schirmer I test, tear osmolarity, ocular surface staining scales, automated conjunctival hyperemia, blink analysis, meibomian gland morphology (meibography/meiboscale), tear inflammatory biomarkers, and safety/tolerability.A teljes eredeti leírásKevesebb
