Abstract

Validate the Correlation between Macular Thickness and Temporal Retinal Nerve Fiber Layer Thickness in Normal Eyes with Age and Refractive Status Using Stratus Optical Coherence Tomography

Highlights

  • Macula is an oval yellowish area in the retina that surrounds the fovea and has the highest visual acuity due to the presence of cones

  • The purpose of this study is to look for any relation between the macular thickness and temporal retinal nerve fibre layer (RNFL) thickness

  • The average macular thickness showed a significant difference throughout the age group from 15 to 25 years (p=0.04) between the age group of 26-35 years (p=0.03) and those more than 45 years of age (p = 0.03)

Summary

Introduction

Macula is an oval yellowish area in the retina that surrounds the fovea and has the highest visual acuity due to the presence of cones. The retinal nerve fibre layer (RNFL) is a sensitive retinal structure, formed by the retinal ganglion axons. It is thickest near the optic disc ( known as porusopticus), gradually diminishing toward the oraserrata. Diseases affecting the retinal nerve fibre layer are like glaucoma, peri-papillary atrophy, optic nerve head atrophy, optic neuritis etc. Assessment of the macular and RNFL region is an important parameter for staging and monitoring of various diseases, this can be done by the optical coherence tomography (OCT) which is a non-invasive imaging test for the retina [1,2,3,4,5]. Optical coherence tomography (OCT) is a safe and reliable imaging test which uses light waves to take
