“…Most of the studies in the literature of normative age-matched data had RNFL analysis by including randomly selected eyes or including only right eye or left eye, considering the fact that either eye could be assessed while calculating normative data by OCTs. [ 9 10 11 12 13 14 15 16 ] The present study illustrates that normal asymmetry should always be taken consideration while assessing average RNFL, quadrant and 12 sector analysis which could be decisive in diagnosing and management, whenever unilateral optic nerve pathology such as unilateral disc edema, optic neuritis, compressive optic neuropathy, and amblyopia is suspected. Diagnosing pediatric glaucoma suspect, periodical follow-up of suspect cases, and established cases of pediatric glaucoma could be monitored if the ophthalmologist is well aware of this asymmetry in RNFL and ONH parameters.…”

“…The RNFL measurements obtained may vary according to the OCT model used, depending on software algorithms, different models, and display scans. [ 5 6 7 8 9 10 11 12 13 14 15 16 17 ] Published literature has evidence-based proof that SD-OCT technology can determine the changes in RNFL thickness much earlier than the time-domain OCT.[ 18 19 20 21 22 23 24 ]…”

“…In published literature, various studies evaluated normative data <18 years of age for various commercially available OCTs. [ 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 ] All these studies concluded that measurements provided by each of the existing commercial imaging devices differ, and measurements taken with one device cannot be used interchangeably with measurements from another device. Even the same device with upgraded software could also depict some variations, and moreover, ethnic variations do exist.…”

Purpose:To determine interocular differences in the retinal nerve fiber layer (RNFL) and optic nerve head (ONH) parameters in a pediatric population using Cirrus high-definition optical coherence tomography (HD-OCT).Methods:Seventy normal Indian children aged 5–17 years presenting to the Pediatric Clinic were included in this observational cross-sectional study. All subjects underwent a comprehensive ophthalmologic examination and an evaluation of the RNFL and ONH by Cirrus HD-OCT. Differences between the right and left eyes were calculated and values were compared by means of a paired t-test. Subjects were also divided into two groups based on age (under or over 10 years of age). Interocular differences in RNFL and ONH parameters together with sex and age variations for these differences were determined.Results:The mean age of studied pediatric population was 11.83 ± 3.3 years (range 5–17). Average RNFL thickness was 94.46 ± 8.7 μm (± SD) (range 77–111). Differences in the average RNFL between right and left eyes were not statistically significant (P = 0.060). Superior quadrant RNFL was thicker in the left eye and temporal quadrant was thicker in the right eye. Among ONH parameters, there were no statistically significant differences in any parameters, except vertical cup-disc (CD) ratio which was significant (P = 0.007). The 2.5%–97.5% limits of asymmetry were 9 μm for average RNFL, 0.14 for average CD ratio, and 0.22 for vertical CD ratio. Mean interocular RNFL thickness differences in superior, superior nasal, and temporal superior quadrants were 10.61 (P < 0.001), 12.57 (P < 0.001), and 4.46 (P = 0.002) μm, respectively. Interocular nerve fiber layer thickness differences were not significantly correlated with sex, while only significant differences with age were observed in 12 clock hour sector analysis, mainly in nasal inferior and inferior quadrant.Conclusions:We report the degree of interocular symmetry of RNFL and ONH parameters measured by Cirrus HD-OCT in a healthy pediatric population. The normal interocular RNFL asymmetry should not exceed 9 μm and vertical CD ratio beyond 0.22 should be considered for further investigations. The physiologic asymmetry provided by this study may assist in identifying changes in RNFL thickness and ONH parameters in pediatric glaucoma and ONH disorders.

“…Recent studies performed in the pediatric age group have detected thicker RNFL when compared with the adult age group. [ 26 27 28 29 30 31 ] In a study performed by Barrio-Barrio et al Cirrus OCT was used and mean RNFL thickness was found as 97.4 ± 9.0 μm. This value was slightly higher than the values in Cirrus database.…”

Purpose:To evaluate the effect of iron deficiency anemia (IDA) on peripapillary retinal nerve fiber layer (RNFL) thickness with optical coherence tomography (OCT).Materials and Methods:102 female patients who had IDA (hemoglobin <12 g/dl, serum transferrin saturation <15%, serum iron <50 μg/dl, and serum ferritin <15 μg/dl) were enrolled in the study. Optic disc and RNFL parameters obtained by Cirrus high-definition OCT 4000 were compared with those of 49 age and sex-matched nonanemic individuals. The time between blood analysis and OCT measurements was 3.14 ± 5.6 (range, 0–28) days in the anemia group, and 3.5 ± 6.7 (range, 0–27) days in the control group (P = 0.76).Results:Average ages of 102 patients and 49 control subjects were 35.76 ± 10.112 (range, 18–66) years, and 36.08 ± 8.416 (range, 19–57) years (P = 0.850), respectively. The average RNFL thickness was 94.67 ± 9.380 in the anemia group, and 100.22 ± 9.12 in the control group (P = 0.001). Temporal, nasal, and lower quadrant average RNFL thicknesses of IDA group were thinner than the control group (P = 0.001, P = 0.013, P = 0.008). Upper quadrant RNFL thicknesses in IDA and control groups were similar. Correlation analysis revealed positive correlation between mean RNFL thickness and hemoglobin (r = 0.273), iron (r = 0.177), ferritin (r = 0.163), and transferrin saturations (r = 0.185), while a negative correlation was found between total iron binding capacity (r = −0.199) and mean RNFL thickness.Conclusions:Peripapillary RNFL thickness measured by OCT is thinner in adult female patients with IDA. It may have a significant influence on the management of many disorders such as glaucoma and neuro-ophthalmological diseases.
