Intense pulsed light therapy: A promising complementary treatment for dry eye disease

Area of Science:

• Ophthalmology
• Medical Technology

Background:

• Dry eye disease (DED) is a prevalent condition causing significant discomfort and visual impairment.
• Conventional medical therapies do not always provide satisfactory symptom control for all DED patients.

Purpose of the Study:

• To evaluate the efficacy of Intense Pulsed Light (IPL) therapy as an adjunctive treatment for dry eye disease.
• To assess the impact of IPL on DED symptoms and objective clinical parameters.

Main Methods:

• Retrospective analysis of medical records from 25 patients (50 eyes) with DED inadequately controlled by medical therapy alone.
• Patients received at least three sessions of IPL therapy.
• Evaluated outcomes included visual analog scale for symptoms, tear Break Up Time (tBUT), Schirmer Test for tear secretion, and Van Bijsterveld score for ocular surface staining, assessed pre-therapy and three weeks post-therapy.

Main Results:

• Significant improvement in dry eye symptoms (P<.05), with the symptom scale median decreasing from 8 to 3.
• Statistically significant improvements observed in tear film stability (tBUT median from 4 to 10), tear secretion (Schirmer test median from 13 to 15), and ocular surface staining (Van Bijsterveld score median from 3 to 2) (P<.05 for all).

Conclusions:

• Intense Pulsed Light (IPL) therapy demonstrates excellent efficacy in alleviating dry eye disease symptoms.
• IPL therapy also shows significant improvements in objective clinical measures, supporting its role as an effective adjunct for managing DED.
