Details and patient eligibility

About

To evaluate the effect of rheumatoid arthritis (RA) activity on the corneal densitometry, corneal curvature (CC), central corneal thickness (CCT), and lens densitometry by Pentacam and compared these parameters with those of age-matched healthy control subjects

Full description

Case - control observational study on RA patients which divided into 2 groups, each group 120 eyes of 60 patients, group 1 of RA in the remission state and group 2 of RA in the active state. Group 3 of 120 eyes of healthy controls. Pentacam was used to measure corneal densitometry, CC, CCT, and lens densitometry. The cornea was divided into 4 concentric zones (0-2, 2-6, 6-10, and 10-12) and anterior, central, and posterior layers according to the depth
