Abstract Details
Purpose:
To evaluate changes in evaporative Dry Eye Disease (DED) due to MGD treated with IPL.
Setting:
Hospital universitario Miguel Servet, Zaragoza
Methods:
A total of 10 patients (20 eyes) suffering from evaporative DED due to MGD, attended to three treatment sessions (days 0-15-45). Each treatment day included: ten periocular pulses of IPL (five in each eye) at the manufacturer recommended intensity
Validated questionnaires about their quality of life OSDI (Ocular Surface Disease Index) and SANDE (Symptom Assessment in Dry Eye) and optical quality parameters (measured with the OQAS) pre- and one month after treatment were analyzed. Corneal and conjunctival staining was evaluated through the validated scales: NEI/Industry Workshop and Oxford. The existence of significant differences was analyzed.
Results:
Improvements were observed in quality of life questionnaires OSDI and SANDE (30.2±12.9 and 60.8±19.1 pre- VS 22.7±12.3 and 51.5±18.6 post-treatment) (p<0.05) as well as in conjunctival and corneal staining scales: NEI /Industry Workshop and Oxford (5.3±4.6 and 1.6±1.4 pre- VS 3.2±3.1 and 1.1±1.3 post- treatment) (p<0.05).
Simulated visual acuity increased. Strehl ratio and the Objective Scatter Index (OSI) changed from 0.15±0.03 to 0.18±0.03 and 1.38±0.65 to 0.87±0.43 (p<0.05), confirming a decrease in aberrations and a lower intraocular scattering of light.
Conclusions:
Dry Eye Disease means a reduction in patient’s quality of life and traditional treatments not always provide total relief of the symptoms. IPL treatment achieves a subjective and objective improvement of evaporative DED. There are still few studies published on the use of IPL, but it seems to have promising results.
