ABSTRACT

PURPOSE: To analyze the association between corneal tomography patterns and atopic conditions in children and adolescents, and to investigate the relationship between corneal tomography findings, sleeping position, and dominant hand.
METHODS: Patients aged 8–16 yr underwent ocular and immunological examinations, including biomicroscopy, corneal tomography, the International Study of Asthma and Allergies in Childhood questionnaire, and an allergy skin test. Based on immunological results, participants were assigned to either the Control Group or the Atopic Group. Tomographic indices were analyzed alongside information on ocular itching, sleeping position, and dominant hand.
RESULTS: A total of 158 patients (mean age: 10.72 ± 2.13 yr) were evaluated, including 34 (21.52%) in the Control Group and 124 (78.48%) in the Atopic Group. Abnormal tomography was observed in 25 patients (15.82%), while 133 (84.18%) had normal results. Comparison between the Control and Atopic Groups regarding ocular itching episodes revealed a statistically significant difference (p≤0.05). Dominant hand and sleeping position showed no statistically significant associations with group classification, tomography results, or ocular itching.
CONCLUSION: Systemic allergies are strongly associated with biomechanical and structural corneal changes, which may or may not progress to different keratoconus patterns. No association was found between eye rubbing and any tomographic parameter, nor between sleeping position or hand dominance and tomography findings.
