Abstract:Objective To investigate the corneal biomechanics of the Mongols in Inner Mongolia with rheumatoid arthritis (RA) and non-RA dry eyes by Corneal Visualization Scheimpflug Technology (Corvis ST). Methods The Mongols in Inner Mongolia Region (all Mongols within three generations) were recruited at the Affiliated Hospital of Inner Mongolia Medical University between December 2015 and May 2018. They were divided into non-RA group (92 cases) and RA group (96 cases). The two groups respectively were performed Corvis ST to detect corneal biomechanics and Corvis ST inspection includes First Applanation Time (A1-time), Second Applanation Time (A2-time), First Applanation Length (A1-length), Second Applanation Length (A2-length), First Applanation Velocity (A1-V), Second Applanation Velocity (A2-V), Highest Concavity Time (HC-time), Maximum Deformation Amplitude (DA), Maximum Highest Concavity Radius (HC-radius), Intraocular Pressure (IOP), Corneal Center Thickness (CCT). The differences of the above parameters between the two groups were examined. Results The differences in age, gender, IOP and CCT were not significant between the two groups (P > 0.05). The Mongols in the RA group had significantly lower A1-time and HC-time, but higher DA compared with the non-RA group (P = 0.01, 0.01, 0.03). Conclusion There are significent differences in corneal biomechanical properties between RA group and non-RA group of the Mongols. The RA group has a significantly shorter A1-time and HC-time, but larger DA compared with the non-RA group.
