Association between ocular biometric measurements and pediatric migraine

Purpose: The aim of this study was to evaluate biometry parameters and anterior segment parameters in pediatric migraine patients compared to controls. Materials and Methods: This prospective case-control study included 40 patients and 45 controls. All participants underwent a complete ophthalmological examination followed by measurement of anterior chamber depth (ACD), vitreous chamber depth (VCD), lens thickness (LT), axial length (AL), central corneal thickness (CCT), corneal volume (CV), anterior chamber volume (ACV), iridocorneal angle (ICA), pupil diameter (PD) and mean keratometry (K-m). Pupil diameter was compared between patients with and without photophobia. All evaluations were made in attack-free period. Pupil diameter was compared in migraine patients with and without photophobia. Intraocular pressure and biometery measurements were taken at the same time of day (10:00-12:00) in order to minimize the effects of diurnal variation. Right eye measurements were included in the study. Results: The two groups showed no statistical differences in ACD, VCD, LT, AL, CCT, CV, ACV, ICA, PD, IOP, spherical equivalent or K-m. There was no difference in PD between patients with and without photophobia. Conclusion: Pediatric migraine patients do not differ from controls in terms of biometry, corneal topography, or keratometry parameters. Studies with larger patient populations are needed to determine the relationship between ocular biometric parameters and migraine.
