Sirius Corneal Topographer: Clinical Tear Testing vs. Noninvasive Methods
Keywords:
ojo seco, topógrafo corneal Sirius, dermatochalasis, estabilidad de la película lagrimal, tiempo de ruptura no invasivoAbstract
Objective: To investigate how noninvasive dry eye assessment using the Sirius corneal topographer integrates into a comprehensive diagnostic protocol for patients with dermatochalasis to optimize preoperative management prior to upper blepharoplasty surgery.
Methods: An observational, descriptive, cross-sectional study was performed with 34 patients. The Sirius corneal topographer was used to measure tear film stability and meibomian gland loss, and the results were compared with the Schirmer I test and fluorescein breakup time.
Results: A statistically significant correlation was found between noninvasive breakup time measurements with Sirius and fluorescein breakup time, as well as with the Schirmer I test, thus demonstrating the usefulness of Sirius in the accurate assessment of tear film stability.
Conclusions: The integration of the Sirius in the diagnostic evaluation of dry eye provides an accurate tool for the detection of tear dysfunction, essential for the effective clinical management of patients with bilateral upper dermatochalasis prior to blepharoplasty surgery. The importance of adopting advanced diagnostic technologies to optimize preoperative care and improve surgical outcomes is emphasized.
