Abstract
Purpose
To assess corneal topography and specular microscopy values in juvenile idiopathic arthritis-related uveitis (JIA-U).
Methods
This case–control study included 30 eyes from JIA-U patients, 20 eyes from JIA patients, and 50 eyes from age- and gender-matched healthy subjects. Patients with a history of ocular diseases or intraocular surgery were excluded. Corneal topography maps (Pentacam HR) and specular microscopy images (CellChek SL) were obtained. The measurements of the groups were compared.
Results
Keratometric astigmatism was higher in the JIA-U group than in the control group (p = 0.040). Patients with astigmatism greater than 1.50D were more common in the JIA-U group than in the control group (p = 0.026). The JIA-U group had higher anterior and posterior elevation values than the control group (p = 0.006, p = 0.025). The density of endothelial cells, coefficient of variation, and hexagonality did not change across groups (p = 0.465, p = 0.096, p = 0.869). The total number of exacerbations and the duration of anterior chamber inflammation were both positively correlated with posterior elevation (r = 0.600, p 0.001; r = 0.583, p 0.001). The age of diagnosis was found to be negatively correlated with anterior elevation (r = −0.412, p = 0.021).
Conclusion
Corneal astigmatism, as well as anterior and posterior elevation values, were all higher in JIA-U patients. Endothelial cell density and morphology, on the other hand, did not differ significantly between groups. Chronic inflammation's impact on stromal remodelling could explain these corneal alterations. The positive correlation between posterior elevation and the number of flares and duration of inflammation represents the importance of early diagnosis and effective treatment.
