Intense pulsed light treatment in meibomian gland dysfunction: Past, present, and future

Area of Science:

• Ophthalmology
• Dermatology

Background:

• Dry eye disease is a prevalent inflammatory condition, often caused by meibomian gland dysfunction (MGD).
• Current treatments for MGD offer limited long-term efficacy.
• Intense pulsed light (IPL) therapy, established in dermatology, is increasingly used in ophthalmology for MGD.

Purpose of the Study:

• To critically review clinical studies on the efficacy of intense pulsed light (IPL) for treating meibomian gland dysfunction (MGD).

Main Methods:

• Systematic review of published clinical studies assessing IPL therapy for MGD.
• Analysis of reported improvements in dry eye symptoms and signs.

Main Results:

• The majority of reviewed studies demonstrated significant improvements in both symptoms and signs of MGD following IPL treatment.
• Treatment efficacy and duration varied based on factors like concomitant therapies and the number of IPL sessions.
• Potential mechanisms of action for IPL in MGD were discussed.

Conclusions:

• IPL therapy is a promising treatment for MGD, offering symptomatic and clinical improvements.
• Further large-scale, randomized, longitudinal studies are required to establish optimal treatment protocols and identify patient responders.
• Integration of biochemical analyses and machine learning may enhance treatment prediction and understanding of IPL's mechanisms.
