Pulsed light therapy for the treatment of dry eyes: retrospective analysis of a series of cases

DOI: 10.37039/1982.8551.2025.0013

ABSTRACT

Objective:

To evaluate the immediate effectiveness of intense regulated pulsed light applied to the periocular area of patients with dry eyes in a retrospective study of a series of cases.

Methods:

Seventy-six participants underwent intense regulated pulsed light therapy, consisting of light pulses applied to both periocular areas. In addition to a comprehensive ophthalmological examination, tear osmolarity measurements were taken for both eyes. Participants were also administered the Ocular Surface Disease Index (OSDI) questionnaire. Data were collected at baseline and 30 days after the final session of intense regulated pulsed light treatment for comparative analysis.

Results:

A statistically significant difference was observed between the mean OsmoOD/OSPre and the mean OsmoOD/OSPost30. Furthermore, a highly significant difference was found between OSDIPre and OSDIPost30.

Conclusion:

Intense regulated pulsed light therapy effectively improved both objective tear osmolarity measurements and the subjective response to the OSDI-IDSO questionnaire in patients with DED over the observed period.
