Purpose:
To evaluate the macular vessel density (VD) in inactive ocular sarcoidosis (OS) and investigate the relationship between VD and both disease duration and visual acuity (VA).
Methods:
This cross-sectional study was performed at a tertiary hospital. The macular VDs of patients with OS were obtained using optical coherence tomography angiography and compared with healthy subjects.
Results:
Deep whole image macular VD (WI-MVD), parafoveal, and perifoveal VDs were lower in OS group (p = .01, p = .01, p = .02, respectively). Negative correlation between disease duration and both superficial and deep WI-MVD, parafoveal, and perifoveal VDs was obtained (for all p < .05). There was a positive correlation between VA and superficial VD (p < .001, r = 0.848 for WI-MVD).
Conclusion:
OS affects deep VD significantly. Changes in superficial VD affect VA more. Disease duration is an important factor affecting macular VD.
