ABSTRACT
Currently, the normative values for retinal nerve fiber layer (RNFL) thickness in our population have not been widely studied. Our study aimed to assess the peripapillary RNFL thickness (RNFLT) with Optopol Copernicus REVO80® spectral-domain optical coherence tomography (SD-OCT) amongst healthy children and its associations. One hundred eighty-two eyes of 91 consecutive healthy children 3 to 16 years of age with a refractive error ≤ ± 5 D were included after a thorough eye exam including visual acuity, refraction, tonometry, pachymetry, axial length estimation, and slit lamp exam including fundus assessment. RNFLT was measured via Optopol Copernicus REVO80® high resolution SD-OCT by a single experienced observer with 3D disc mode within a circular area of diameter 3.45 mm and the ring further divided into four quadrants inferior, superior, nasal, and temporal. The mean age was 11.12 ± 3.12 years (range, 3-16). The average RNFLT was 120.13 ± 12.6 µm. The mean superior RNFL was the thickest at 138.21 ± 16.6 µm, next was the mean inferior RNFLT at 137.62 ± 17.2 µm, followed by the nasal 91.61 ± 18.5 µm and then the temporal at 74.58 ± 11.7 µm. No significant differences in RNFLT were noted between the two eyes. The mean RNFLT was significantly higher in males as compared to females, in vertical quadrants and at an average (p < 0.05). No significant relationship was found between the average RNFLT and factors such as age, axial length, corneal thickness, cup-to-disc ratio, intraocular pressure, or refractive error. This study establishes normative values of RNFLT for this subgroup of Pakistani children for the Optopol Copernicus REVO80® SD-OCT device.
