The purpose of the present study was to evaluate the thickness of the peripapillary retinal nerve fiber layer (RNFL) and retinal ganglion cell–inner plexiform layer (GCIPL) in adult-onset familial Mediterranean fever (FMF).
Forty two adult-onset FMF patients and forty two healthy controls were included in the present study. Detailed ocular examination was performed, and then the thickness of the peripapillary RNFL and GCIPL was measured by Spectral domain optical coherence tomography. The patients were divided into two groups according to their disease severity score, M694V gene mutation, colchicine dosage used per day, colchicine usage time period and number of FMF attacks per year.
There were no statistically significant differences in peripapillary RNFL and retinal GCIPL thickness in patients with adult-onset FMF and controls.
According to our study, it looks like that neither adult-onset FMF nor colchicine has any effect on the RNFL and GCIPL thicknesses. Further studies with a large sample size are needed.
