Corneal parameters in pediatric triple a syndrome patients with alacrima

Le résumé fourni par la source

Introduction To evaluate the changes in central corneal thickness and curvature parameters in pediatric patients with Triple A syndrome and alacrima.Methods This retrospective study included 52 eyes of 26 patients with Triple A syndrome. All patients had alacrima. Pentacam was used to analyze the keratometry in the flat (K1) and steep meridian (K2) and maximum keratometry (Kmax), mean keratometry (Kmean) readings, central corneal thickness at the vertex (CCT) and at the thinnest point (CCT-TP) were recorded. Patients were divided into three groups based on their age (Group 1: 3–6 years, group 2: 7–12 years, group 3: 13–18 years). Values were compared between pediatric patients with Triple A and normal controls.Results The K1 values of all patients were significantly higher than those observed in healthy data (p < 0.001). 15 Group 1 had significantly lower K2 and higher CCT values (p = 0.008, p = 0.015). In group 2, K1 and Kmax were significantly higher, while CCT and CCT-TP were lower (p = 0.016, p < 0.001, p < 0.001, p < 0.001, respectively). In group 3, K1 and CCT and CCT-TP were significantly higher than the normal data (p = 0.019, p < 0.001, p < 0.001, respectively).Discussion Since dry eye syndrome may cause corneal changes, in AAAS patients, corneal topographic variations may occur due to alacrima. Thus, these patients should be evaluated during follow-up visits.
