Effectiveness of Low Level Light Therapy and Intense Pulse Light on Mite Count as Adjuntive Therapies in Demodex Blepharitis Using Artificial Intelligent Program (Ai-Demodex)
Sponsor: Chulalongkorn University
Summary
Primary Objective: To evaluate the efficacy of LLLT, IPL, and IPL + LLLT in re ducing demodex count in patients with Demodex Blepharitis. Secondary Objectives: To evaluate the efficacy of LLLT, IPL, and IPL + LLLT in improving ocular surface parameters in Demodex Blepharitis. Sample Size: 88 participant ( 22 participants per group x 4 groups) Study Design: 2x2 Factorial randomized trial. Methodology: The study is composed of 4 groups including 1) control 2) Blue light LLT alone 3) IPL alon e, 4) Blue light LLLT with IPL , and . Both LLLT and IPL will treat weekly for 4 sessions All participants will be instructed to perform warm compression and lid scrub. The outcomes include demodex count, meibum grading and ocular surface parameter were evaluated at 1 and 3 months post treatment.

Interventions
The blue MY MASK-E
Device-Specific Protocol Blue MyMask® LLLT (Espansione): Emits monochromatic photobiomodulation therapy at 633 nm, distinct from conventional red or near-infrared LLLT used in other studies. Espansione IPL: Uses a patented Optimal Power Energy (OPE®) system with a polychromatic spectrum of 590-1200 nm, allowing sub-threshold energy pulses for selective thermal effects on abnormal telangiectasia and Demodex-related inflammation.
IPL
IPL : The Eye-light device (Espansione Marketing S.p.A., Bologna, Italy,waveleggths 1,200-1,500 nm, Delivery system 12cm2) (Thai FDA No 66-2-2-2-0012685) : * Protective eye shields * 5 flashes of light were applied for each eye (3 along the inferior orbital rim, 1 at the lateral canthus, and 1 applied horizontally along the inferior orbital rim) * Therapeutic energy level (10-16 joules/ cm2) based on the degree of skin pigmentation.
Mechanical with pharmacological treatment
Mechanical with pharmacological treatment : Warm compression 15 minutes + Lid hygiene + 1% TTO 2 times per day for 90 days 1%TTO : OCuSOFT Oust Demodex Eyelid Cleanser Foam Bottle 50ml (OCuSOFT, Richmond, TX) is the only commercially available medication in Thailand that contains 1% tea tree oil.
