Les facteurs de risque de kératocône : étude transversale cas-témoin monocentrique

Abstract : Objective: to evaluate risk factors associated with keratoconus in a monocentric cross-sectional case–control study. Methods: this observational study occurred from June 2019 to February 2021 in Gui de Chauliac University Hospital Center, Montpellier, France. The case group consisted of 195 patients with keratoconus in at least one eye who were followed by a corneal specialist. The control group consisted of 195 patients without evidence of keratoconus on slit-lamp examination and corneal topography, who were matched 1:1 to controls by age and sex. Data were collected by a self-completed paper questionnaire before the consultation. Results: multivariate analysis revealed significant associations of keratoconus with family history (odds ratio [OR]= 22.2, 95% confidence interval [CI]: 5.88–148; p<0.001), rubbing eyes (OR= 10.9, 95% CI: 6.35–19.3; p<0.001), allergy (any kind) (OR= 3.80, 95% CI: 2.26–6.54; p<0.001), smoking exposure (OR= 2.08, 95% CI: 1.15–3.85; p=0.017) and dry eyes (OR= 1.77, 95% CI: 1.02–3.09; p=0.045). The worst eye was associated with the more rubbed eye (p<0.001) and the more pressed eye during the night according to sleeping position (p<0.041). Conclusions: this study confirmed the association between keratoconus and eye rubbing, family history and allergy. It highlighted the role of pressure on the eyes during sleeping. Other less known risk factors such as dry eyes and smoking exposure should be explored in future studies.
