Abstract
Background: OCT is a useful tool for differentiating early stages of glaucoma in children as well as adults. Having a normative reference range for children helps in detecting such serious disease and treating it in earlier phases however, children’s normative data are not provided by the OCT software. Aim: to share and establish reference values and data about retinal nerve fiber layer and ganglion cell complex thickness in the child age group, helping later earlier detection of disorders that possess damaging effects on such layers as glaucoma. Patients and Methods: one hundred thirty-five children were enrolled and divided into two groups, group including all emmetropic children with spherical equivalent between ≥ -1 and ≤ +1 diopter and group B including all myopic children with spherical equivalent between (≤ -1 and up to - 6 diopter)Measurement of retinal nerve fiber RNFL and ganglion cell complex GCC layer thickness using OCT scans were done using DRI OCT Triton plus. Results: Total retinal nerve fiber layers were thinner among the myopic group (106.2±5.65µm) than the emmetropic group (111.7±6.39µm) (p < 0.001). The total ganglion cell complex layer was thinner among the myopic group (65.99±2.72µm) than the emmetropic group (70.22±2.84µm) (p < 0.001). All RNFL and GCC thickness measurements showed significant indirect weak correlations with age. There is a significant correlation between axial length with (superior RNFL, average RNFL, superior GCC, inferior GCC, and total average GCC measurements). But no significant correlations were found between AL with Inferior RNFL thickness and age. Conclusion: Our study clearly demonstrates that myopic eyes have a thinner RNFL and GCC than emmetropic eyes. On one hand, this thinning may be a risk factor for glaucoma development, as variations in the arrangement of optic nerve head fibers have been postulated to render myopic eyes more susceptible to glaucomatous damage.
