Purpose: To evaluate the ocular surface temperature (OST) using an infrared thermography camera in Sjögren Syndrome (SS) patients compared with healthy subjects and correlate these results with the dry eye symptomatology, tear volume, stability and matrix metalloproteinase 9 (MMP-9) concentrations.
Methods: Twelve patients of primary SS (46.64 ± 13.34 years), and twenty volunteers (41.38 ± 9.67 years) without dry eye, participated in this study. OSDI questionnaire, Schirmer test, tear break up time (TFBUT), matrix metalloproteinase 9 (MMP-9) concentrations and OST were evaluated.
Results: Central cornea temperature was statistically higher in SS than in control group (p = 0.014), being 34.81 ± 0.37ºC and 34.25 ± 0.65ºC respectively. In the control group, the temperature increase.. View More»
