Abstract
ABSTRACT Purpose To evaluate the macular vessel density (VD) in inactive ocular sarcoidosis (OS) and investigatethe 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 OSwere obtained using optical coherence tomography angiography and compared withhealthy 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 diseaseduration and both superficial and deep WI-MVD, parafoveal, and perifoveal VDswas obtained (for all p < .05). There was a positive correlation between VAand 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.
