Methods
This study was undertaken in an elementary school from December 2010 through March 2011 as part of the Environmental Fetal Factors in the Development of the Optic Nerve and the ReTina study (EFFORT). From the 598 eligible children, 358 were included in the study, giving an acceptance rate of 60%. One hundred healthy children were recruited prospectively and consecutively from among the 358 for the reproducibility and repeatability study.16
All subjects underwent a comprehensive ophthalmologic
Results
One hundred children were included in the study (52 boys and 48 girls). The age of the patients ranged from 6.22 to 11.31 years, with a mean age of 9.15 years. Mean best-corrected visual acuity (logarithm of the minimal angle of resolution) was −0.01 (20/20 Snellen equivalent), with a range from 0.3 to −0.2. The refractive errors ranged from −3.00 to +4.50 of spherical equivalent. Stereoacuity was full (60 seconds of arc or better) in 94 children and was reduced (worse than 60 seconds of arc)
Discussion
OCT is part of daily clinical practice. Reliability and repeatability of diagnostic tools need to be ascertained, especially in children, whose cooperation is limited. Cirrus OCT represents the latest commercially available generation of OCT, with higher axial resolution compared with conventional time-domain OCT. To our knowledge, this is the first report of the study of the reproducibility of the RNFL and macular measurements using high-density FD OCT in healthy children.

2022, Photodiagnosis and Photodynamic TherapyCitation Excerpt :The degree of damage to visual pathways causes a decrease in the RNFL thickness, which can hinder visual recovery despite treatment [18]. The repeatability of the decrease in the RNFL thickness in paediatric glaucoma patients compared to healthy children has been observed using several types of SD-OCT devices in previous studies [19,20]. Similarly, in one study in which children with congenital glaucoma were compared with healthy children, decreased thickness of RNFL was shown in both papillary and macular analyses in all sectors in the congenital glaucoma group [21].
