Abstract

Objective: This study aimed to evaluate retinal nerve fiber layer (RNFL) thickness in healthy individuals with
myopic and hypermetropic eyes, using optical coherence tomography (OCT).
Study Design: A cross-sectional study.
Place and Duration of Study: The study was carried out at the Department of Ophthalmology, Dr. Akil bin
Abdul Qadir Institute of Ophthalmology, Karachi, Pakistan from January 2015 to June 2015.
Methods: In this study, 300 eyes were included were examined using standard protocols by a single examiner.
Subjects with a history of diabetic or hypertensive retinopathy, raised intraocular pressure (> 21mmHg), and
previous intraocular or laser surgery were excluded from the study. The mean retinal nerve fiber layer thickness
was calculated in both myopic and hypermetropic eyes.
Results: The mean global retinal nerve fiber layer thickness (RNFLT) in myopic eyes was found to be 93.98 ± 8.57 μm. In hypermetropic eyes, it was found to be 101.00 ± 6.58. This variation was found to be statistically
significant with p-value of 0.001.
Conclusion: We concluded that individuals with myopic eyes had significantly reduced retinal nerve fiber layer
thickness whereas those with hypermetropic eyes showed an insignificant increase in RNFLT compared to
emmetropic eyes.
