Conditions

Dry Eye Disease (DED)

Keywords

Topical Cyclosporine A, Topical Tacrolimus, Low-level light therapy

Brief summary

The objective of the study is to evaluate the effectiveness of Low-level light therapy (LLLT) in combination with either topical Cyclosporine A (CsA) or topical Tacrolimus, using each non-steroidal immunosuppressant as an active control.

Interventions

Three 15-minute sessions were performed at weekly intervals. The treatment was delivered with a wavelength of 625 nm and a radiance of 35 mW/cm², resulting in a total energy dose of approximately 32 J/cm² applied to the facial and eyelid regions with eyes closed.

CsA 0.1% twice per day

Tacrolimus 0.1% twice per day

Design outcomes

Primary

MeasureTime frameDescription
Ocular surface disease index (OSDI)From baseline visit to the end of follow-up (12 months)A standardized questionnaire designed to assess the symptoms of dry eye disease and their impact on vision-related functioning. It consists of 12 items that evaluate the frequency of symptoms, environmental triggers, and functional limitations over the previous week. The OSDI provides a score from 0 to 100, with higher scores indicating more severe symptoms.

Secondary

MeasureTime frameDescription
Non-invasive tear film break-up time (NIBUT)From baseline visit to the end of follow-up (12 months)NIBUT is a clinical test used to evaluate tear film stability without the use of dyes. It measures the time interval between a complete blink and the first appearance of a disruption or break in the tear film. Shorter NIBUT values indicate reduced tear film stability.
Tear meniscus height (TMH)From baseline visit to the end of follow-up (12 months)TMH is a quantitative parameter used to assess tear volume. Reduced TMH values are indicative of aqueous tear deficiency.
