“… 6 , 8 , 10 Therefore, the variation of RNFLT from normative data in myopic eyes and the change in RNFLT caused by myopia have been investigated by many researchers. 11 , 12 , 13 , 14 In the current study, unlike previous research, in addition to the interaction between myopia and RNFLT, we investigated the differences in the color codes of RNFLT in myopic eyes compared to emmetropes using color maps, which are frequently utilized by ophthalmologists in routine clinical practice.…”

Objectives: To determine the normal values for retinal nerve fiber layer thickness (RNFLT) in myopic patients without glaucoma and analyze the changes in their color map. Materials and Methods: A total of 245 eyes without glaucoma were included in the study. According to the degree of myopia, the cases were divided into 4 groups: control group (+1.00/-1.00 D; n=70), Group 1 (-1.00/-3.00 D; n=50), Group 2 (-3.00/-6.00 D; n=75), and Group 3 (>-6.00 D; n=50). Intra-group comparisons were performed in terms of superotemporal, superonasal, nasal, inferonasal, inferotemporal, temporal, and global RNFLT (Heidelberg Spectralis, Optic Coherence Tomography, Germany) and the color coding of these quadrants (green: within normal limits, yellow: borderline, red: outside normal limits). Results: All groups were similar in age and gender (p>0.05). As the degree of myopia increased, RNFLT became thinner in the upper and lower temporal and upper and lower nasal quadrants (p<0.01). The rate of measurements considered borderline and outside normal limit in at least 1 quadrant was higher in groups with higher myopia for all quadrants (p<0.05). This rate was found to be 8/70 (11.4%) for the control group, 9/50 (18.0%) for Group 1, 21/75 (28.0%) for Group 2, and 33/50 (66.0%) for Group 3 (p<0.01). Conclusion: The high rate of RNFLT classified as borderline or outside normal limits in myopic patients is a finding to which clinicians should pay attention in order not to make a misdiagnosis, especially in cases of suspected glaucoma.
