Purpose: Our aim was to evaluate the thickness of central macula and retinal nerve fiber layer in patients with knee osteoarthritis. Methods: Twenty-six eyes of 26 patients with knee osteoarthritis and 26 eyes of 26 age-gender matched healthy controls were included in this cross-sectional and comparative study. All participants underwent a standardized ophthalmological examination including visual acuity assessment, biomicroscopy evaluation, air-puff tonometry measurement and retinal examination. Optical coherence tomography was used to measure the thickness of central macula and retinal nerve fiber layer. Results: The average age of the patients with knee osteoarthritis and healthy controls were 60.8 ± 8.2 and 58.0 ± 9.8 years, respectively (p=0.46). In both groups, there were 8 male and 18 female participants (p=1.00). The average central macular thickness was 264.2 ± 22.1 μm in the osteoarthritis group and 262.9 ± 20.1 μm in the healthy controls (p=0.88). The average retinal nerve fiber layer thickness was 105.4 ± 9.9 μm in the osteoarthritis group and 103.9 ± 10.1 μm in the healthy controls (p=0.81). Conclusions: The thicknesses of central macula and retinal nerve fiber layer were similar in patients with osteoarthritis and healthy controls.
