Correlation of retinal nerve fiber layer thickness with perimetric staging in primary open-angle glaucoma - A cross-sectional study
Background: Glaucoma is a progressive optic neuropathy, characterized by structural optic nerve damage with corresponding field defects. Primary open-angle glaucoma (POAG) is the most common. Although perimetry is the gold standard, retinal nerve fiber layer (RNFL) thickness by spectral-domain optical coherence tomogra …
