Correlation of peripapillary retinal nerve Fibre layer thickness and macular ganglion Cell layer- inner plexiform layer thickness With visual field changes in patients of Primary open angle glaucoma by spectral Domain optical coherence tomography.

Abstract

ABSTRACT Introduction Primary open-angle glaucoma (POAG) is a chronic optic neuropathy leading to progressive retinal ganglion cell (RGC) loss, retinal nerve fiber layer (RNFL) thinning, and visual field (VF) defects. Early detection and disease monitoring are critical in preventing irreversible blindness. Spectral-domain optical coherence tomography (SD-OCT) has emerged as a valuable imaging tool for assessing peripapillary RNFL and macular ganglion cell layer-inner plexiform layer (GC-IPL) thickness. This study aims to evaluate structural damage in POAG patients using SDOCT and correlate these findings with visual field changes determined by Humphrey Visual Field (HVF) analysis.
