Thin neuroretinal rim
WebJul 22, 2024 · 1. Introduction. Glaucoma is a progressive optic neuropathy accompanied by a deficit of the retinal nerve fiber layer (RNFL) with a corresponding thinning of neuroretinal rim (NRR) tissue that can lead to progressive visual field defect [1,2].Noticeable structural changes by current instruments may precede functional visual field loss in an early stage … WebPrecis: In open-angle glaucoma, when neuroretinal rim tissue measured by volumetric optical coherence tomography (OCT) scans is below a third of the normal value, visual field (VF) damage becomes detectable. Purpose: To determine the amount of neuroretinal rim tissue thickness below which VF damage becomes detectable. Methods: In a …
