Purpose:  To determine the difference between mean retinal nerve fiber layer (RNFL) thickness in myopic eyes (up to -6.00D) and normal eyes. Study Design:  Descriptive observational study. Place and Duration of the Study:  Eye department of Mayo hospital Lahore, from February 2019 to April 2019. Methods:  We compared the mean RNFL between 58 myopic eyes (up to -6.00 D) and age matched 60 normal eyes. The age of the participants was between 12 to 42 years. Complete ocular examination was done and RNFL thickness was measured by using Optical coherence tomography (NIDEX RS-33.0, software-ex 1.5.2).Data was analyzed by independent sample t-test by using SPSS; with P < .05 as significant. Results:  The mean difference among these groups was 5.852 µm with (SE: 1.929). Mean RNFL thickness in myopic group was (95.93 ± 10.158µm) with (SE: 1.334). The result for mean RNFL thickness in myopic eyes was distributed normally as P < .03. Mean RNFL in normal group was (101.78 ± 10.774 µm) with (SE: 1.391), and the result of mean RNFL thickness measured in normal eyes was not distributed normally as P < .20. The results showed that there is a statistically significant difference between mean RNFL thickness measured in normal versus myopic eyes as (P < .003). Conclusion:  There is a significance difference between mean RNFL thickness between myopic eyes and normal eyes as measured by OCT. Careful interpretation of RNFL data in myopic eyes is recommended to avoid misdiagnosis with glaucoma. Key Words:  Retinal Nerve Fiber Layer thickness, Myopia, Optical Coherence Tomography.

Purpose: The purpose of this study is to investigate the relationship between macular and peripapillary retinal nerve fiber layer thickness and amblyopia. Methods: A total of 56 pediatric patients with hyperopic anisometropic amblyopia were evaluated in this study. As the control group, we used the patients’ fellow eyes. A comprehensive eye examination was performed, including best-corrected visual acuity with Snellen charts (converted to logMAR for analysis), slit-lamp examination, fundus examination, cover and, cover-uncover testing, and ocular motility testing. The macular thickness, retinal nerve fiber layer thickness, axial length and optic disc area of both eyes were measured. Results: The mean age was 7.25±1.89 years. For the amblyopic and fellow eyes, the mean best-corrected visual acuity was 0.33± 0.20 logMAR and 0.0± 0.0 logMAR, respectively. Macular center thicknesses were 225,55±18,86 µm and 215,7±12,96 µm in amblyopic and fellow eyes, respectively. Macular 6mm ring thicknesses were 281,32±33,51 µm and 256,07±28,91 µm in amblyopic and fellow eyes, respectively. RNFLT were 108,39±11,59 µm and 104,61±8,43 µm in amblyopic and fellow eyes, respectively There was a statistically significant difference in the macular center thickness, in macular 6-mm ring area thickness and in RNFLT (p<0.05). There was a positive correlation between visual acuity of amblyopic eyes and macular thickness and RNFLT. Conclusions: This study explored objectively measured retinal changes in amblyopia and found a slightly thicker central macular region and 6-mm ring area thicknesses and RNFLT in amblyopic compared with normal eyes.
