Structural assessment of the optic nerve in patients with obstructive sleep apnea syndrome: Case-control study.

Even if the retinal ganglion cell-inner plexiform layer thicknesses did not significantly differ between the obstructive sleep apnea syndrome and control groups, obstructive sleep apnea syndrome patients showed a decreased peripapillary nerve fiber layer thickness and increased optic nerve head parameters. These findings can be used as an indicator of optic nerve damage in the early diagnosis of obstructive sleep apnea syndrome patients.
