Comparative study of the meibography’s measurement with Antares topography and the Cobra HD’s eye fundus camera.

Abstract

Purpose : Objective: To know the comparability of Meibomian glands loss measurement between two equipment of Meibography.

Methods : Materials and Methods: A prospective, transversal and observational studies were conducted. All the participants answer a questionnaire of dry eye symptoms (OSDI), afterwards, it was carried out a complete ophthalmology evaluation and studies in the following order: (1) Fluorescein staining of the eye surface; (2) Non – invasive tear rupture time (Antares Topgrapgy); (3) Meibography with the Cobra and Antares equipment.

Results : Results: 56 right eyes of 56 patients were studied, with an average age of 33.88 ± 16.42 years, 53.%% were masculine. The average loss of Meibomian glands of the upper eyelid was of 18.60 ± 7.43 with Antares’s equipment and 17.70 ± 6.85 with Cobra’s equipment (p=0.079). The average loss of Meibomian glands of the lower eyelid was of 23.39 ± 8.31 with Antares equipment and 21.82 ± 6.29 with Cobra’s equipment (p=0.418). Statistically, there was not a significance difference. The concordance limits of the comparison between this two equipment was 6.159,-7.945 for the upper eyelid and 16.63,-13.48 for the lower eyelid.

Conclusions : Conclusions: Both equipment measure similarly the loss of the Meibomian glands, so they both can be use the same way.
