Increased corneal ectasia risk in patients with familial mediterranean fever

Purpose: To evaluate the corneal tomographic parameters in patients with familial Mediterranean fever (FMF) and to compare data with those of healthy control subjects. Materials and Methods: Forty eyes of 40 patients with FMF (FMF group) and 35 eyes of 35 healthy subjects (control group) were included to this prospective study. All participants underwent complete ophthalmological examination and tomographic analysis with Pentacam HR. Maximum keratometry, front and back astigmatism, thinnest pachymetry, maximum anterior and posterior elevation best-fitsphere (BFS) at the 5.0 mm zone, front and back difference elevation, final D, average and maximum pachymetric progression index, and maximum Ambrósio relational thickness parameters were noted. Results: Groups were similar in terms of age and gender (p = 0.77 and 0.35). Maximum keratometry, thinnest pachymetry, front and back astigmatism, and maximum anterior elevation BFS at the 5.0 mm values ​​were similar between groups (p = 0.22, 0.52, 0.49, 0.29, and 0.31, respectively). Maximum posterior elevation BFS at the 5.0 mm and back difference elevation values ​​were higher than control group in FMF group (p = 0.001 and 0.04). The mean values ​​of final D, average and maximum pachymetric progression index were higher, and Ambrósio relational thickness was lower in FMF group compared to control group (p = 0.03, 0.002, 0.006, and 0.01, respectively). Conclusions: FMF patients carry increased corneal ectasia risk compared to healthy subjects. The corneal tomographic characteristics and the association of keratoconus with FMF may be important in a detailed refractive surgery work-up.
