Purpose: To analyze the changes of corneal endothelial cells in Chinese patients with unilateral Fuchs' uveitis syndrome (FUS) and investigate the factors relevant to these changes.
Methods: Bilateral specular microscopic examination was performed in 459 Chinese patients with unilateral FUS from April 2008 to April 2023. The affected eyes constituted the study group, while the contralateral eyes served as controls.
Results: The median values of endothelial cell density (ECD), cell count, total cell size, and hexagonality were significantly lower in the FUS eyes compared to the control eyes ( < 0.001). The median values of average cell size, maximum cell size, SD of cell size, and CV were significantly higher in the FUS eyes compared to the control eyes ( < 0.001). Central ECD showed a negative correlation with age ( = -0.339; < 0.001), maximum IOP ( = -0.127; = 0.006), and the interval since symptom onset ( = -0.172; < 0.001). The ECD was lower in eyes with ocular hypertension compared to those without ocular hypertension ( < 0.001). Eyes with KPs distributed on the central corneal endothelium had a significantly lower ECD than those with KPs distributed diffusely or KPs distributed triangularly on the inferior corneal endothelium ( = 0.006).
Conclusion: Our findings suggest decreased ECD, increased cell size, and morphological alterations in the affected eyes of Chinese patients with FUS. The reduction in ECD is correlated with age, elevated IOP, the interval since symptom onset, and the distribution of KPs.
